The 2018 Pacific hurricane season was one of the most active Pacific hurricane seasons on record, producing the highest accumulated cyclone energy value on record in the basin. The season had the fourth-highest number of named storms{{snd}}23, tied with 1982.{{#tag:ref|An average Pacific hurricane season, as defined by the National Oceanic and Atmospheric Administration, has fifteen tropical storms, seven hurricanes and three major hurricanes.|group="nb"}} The season also featured eight landfalls, six of which occurred in Mexico. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, tropical cyclone formation is possible at any time of the year, as illustrated when the first tropical depression formed on May 10, five days prior to the official start of the season.

The second named storm of the season, Hurricane Bud, struck Baja California Sur in mid-June, causing minor damage. Tropical Storm Carlotta stalled offshore of the Mexican coastline, where it also caused minor damage. In early August, Hurricane Hector became one of the few tropical cyclones to cross into the Western Pacific from the Eastern Pacific, while also affecting Hawaii. Tropical Storm Ileana brought torrential rainfall to southwestern Mexico during early August, causing relatively minor damage. A few weeks later, Hurricane Lane obtained Category 5{{#tag:ref|Hurricanes reaching Category 3 ({{convert|111|mph|km/h|disp=or|sp=us}}) and higher on the five-level Saffir–Simpson wind speed scale are considered major hurricanes.|group="nb"}} intensity while also becoming Hawaii's wettest tropical cyclone on record and the second wettest tropical cyclone in United States history, only behind Hurricane Harvey of the previous year. Hurricane Olivia also struck Hawaii, resulting in relatively minor damage.

In late September, Hurricanes Rosa and Sergio formed, both of which eventually brought thunderstorms and flash flooding to the Baja California Peninsula and the Southwestern United States. Tropical Depression Nineteen-E became the first tropical cyclone to form in the Gulf of California before it brought severe flooding to Sinaloa, Mexico, causing significant damage. Meanwhile, Hurricane Walaka attained Category 5 intensity before causing disruptions in the Northwestern Hawaiian Islands. In late October, Hurricane Willa became the record-tying third Category 5 hurricane of the season (tied with the 1994 and 2002 seasons) before striking Sinaloa as a major hurricane, causing severe damage. Tropical Storm Vicente simultaneously affected the region just south of where Willa made landfall, causing severe flooding and dozens of landslides. Altogether, six systems made landfall this season. Damage across the basin reached $1.64 billion (2018 USD),{{refn|All damage totals are valued as of 2018 and in United States dollars, unless otherwise noted.|group="nb"}} while 57 people were killed by the various storms.

The National Oceanic and Atmospheric Administration (NOAA) released its annual forecast on May 24, 2018, predicting an 80% chance of a near- to above-average season in both the Eastern and Central Pacific basins, with a total of 14–20 named storms, 7–12 hurricanes, and 3–7 major hurricanes. The reason for their outlook was the possible development of an El Niño, which reduces vertical wind shear across the basin and increases sea surface temperatures. In addition, many global computer models expected a positive Pacific decadal oscillation (PDO) that had been ongoing since 2014 to continue. PDO is a phase of a multi-decade cycle that favors much warmer than average sea surface temperatures, which is in contrast to the 1995–2013 period, which featured below-normal activity.{{Cite web | title=NOAA: 2018 Eastern Pacific Hurricane Season Outlook | url=http://www.cpc.ncep.noaa.gov/products/Epac_hurr/Epac_hurricane.html | date=24 May 2018 | publisher=National Oceanic and Atmospheric Administration | work=Climate Prediction Center | access-date=27 October 2018 | archive-url=https://web.archive.org/web/20090614024616/http://www.cpc.ncep.noaa.gov/products/Epac_hurr/Epac_hurricane.html | archive-date=14 June 2009 | url-status=live }} The Servicio Meteorológico Nacional (SMN) issued its first forecast for the season on May 25, predicting a total of 18 named storms, 6 hurricanes, and 4 major hurricanes to develop.

A well-defined tropical wave departed from the western coast of Africa during the middle of June 14. It moved across the Atlantic Ocean without development, and the wave entered the Pacific Ocean on June 24. There, its convection increased as it interacted with the Pacific monsoon trough. The system continued to organize over the next couple of days as it moved north of west, developing into a tropical depression on June 27 at 18:00 UTC, while about {{convert|470|mi|km|abbr=on|round=5}} southwest of Manzanillo, Mexico. The depression slowly intensified, becoming Tropical Storm Emilia around 12:00 UTC on June 28. Despite moderate wind shear, Emilia attained peak winds of {{convert|50|kn|mph km/h|abbr=on|round=5|sortable=on|order=out}} on June 29 about {{convert|600|mi|km|abbr=on|round=5}} southwest of the southern tip of the Baja California peninsula. The storm briefly maintained this intensity before a combination of shear, mid-level dry air, and cooling sea surface temperatures caused it to weaken. By 12:00 UTC on June 30, Emila had weakened into a tropical depression. The system decayed into a remnant low by 00:00 UTC on July 2 as it continued west-northwest. The remnants of Emilia dissipated around 54 hours later while over {{convert|1,495|mi|km|abbr=on}} west of Baja California.{{cite report |last1=Stewart |first1=Stacy |title=Tropical Cyclone Report: Tropical Storm Emilia |url=https://www.nhc.noaa.gov/data/tcr/EP062018_Emilia.pdf |publisher=National Hurricane Center |access-date=16 June 2020 |date=7 August 2019 |archive-url=https://web.archive.org/web/20180828071331/https://www.nhc.noaa.gov/data/tcr/EP062018_Emilia.pdf |archive-date=28 August 2018 |url-status=live }}

A tropical wave emerged from the western coast of Africa on June 16, and ten days later it crossed Central America into the Eastern Pacific Ocean. Convection increased markedly thereafter as the wave continued westward for the next couple of days, developing a low-pressure area on June 28. A tropical depression developed at 18:00 UTC on June 30, while approximately {{convert|575|mi|km|abbr=on|round=5}} south of Manzanillo, Mexico. A mid-level ridge located over central Mexico steered the nascent depression towards the west-northwest as the storm continued to intensify. The depression strengthened into Tropical Storm Fabio around 06:00 UTC on July 1. Located within a favorable environment of warm sea surface temperatures, moist air, and low wind shear, Fabio continued to consolidate over the next couple of days. Fabio became a Category 1 hurricane around 12:00 UTC on July 2. The storm peaked at 18:00 UTC on the next day as a high-end Category 2 hurricane with winds of {{convert|95|kn|mph km/h|round=5|order=out|abbr=on|sortable=on}} and a pressure of {{convert|964|mbar|inHg|abbr=on|sigfig=4}}, while located {{convert|645|mi|km|abbr=on}} southwest of the southern tip of the Baja California peninsula.

A tropical wave exited the western coast of Africa on July 13, and moved across the Atlantic, eventually entering the Pacific Ocean on July 22. Over the next couple of days, the wave continued westward with its convection pulsing intermittently. The low-level center and the convection organized into a tropical depression by 12:00 UTC on July 26, approximately {{convert|1,035|mi|km|abbr=on}} southwest of the southern tip of the Baja California peninsula. Over the next 12 hours, the nascent depression traveled northwest along the south-southwestern edge of a mid-level ridge while intensifying; the system became Tropical Storm Gilma six hours after formation. Gilma reached its peak intensity of {{convert|40|kn|mph km/h|abbr=on|round=5|sortable=on|order=out}} winds and a pressure of {{convert|1005|mbar|inHg|abbr=on|sigfig=4}} at 06:00 UTC on July 27, while located {{convert|1,210|mi|km|abbr=on}} west-southwest of the southern tip of the Baja California peninsula. The tropical storm began to succumb to increasing northwesterly wind shear soon after, resulting in the degradation of its convection; Gilma weakened into a tropical depression by 18:00 UTC on the same day. The depression had limited thunderstorm activity over the next couple of days before weakening into a remnant low around 12:00 UTC on July 29. The remnants crossed into the Central Pacific basin and dissipated two days later, around {{convert|405|mi|km|abbr=on|round=5}} southeast of Hilo,

A passing Kelvin wave and a tropical wave increased convection within the ITCZ; after this increase, a low-pressure trough spawned within the monsoon trough on July 21, approximately {{convert|635|mi|km|abbr=on}} south-southwest of Manzanillo, Mexico. Over the next several days, the system moved westward while experiencing northeasterly wind shear, which was imparted by an upper-level trough. The aforementioned combined with a moderately dry environment prevented the low-pressure trough from organizing further. The system generated some convection on July 23, but increasing wind shear prevented significant organization until July 26. The system reached a col or neutral point between the upper-level trough to the east and an upper-level ridge to the west. This allowed a tropical depression to form around 18:00 UTC on that day, approximately {{convert|1,440|mi|km|abbr=on}} east-southeast of Hilo, Hawaii. The depression's convection was quickly removed to the south and west of its center as it entered a region of higher wind shear. This caused the depression to decay into a trough of low-pressure by 00:00 UTC on July 28, located about {{convert|1,210|mi|km|abbr=on}} southeast of Hilo, Hawaii. The remnants produced sporadic convection as they continued westward over the Central Pacific during the next few days before dissipating.{{cite report |last1=Zelinsky |first1=David |title=Tropical Cyclone Report: Tropical Depression Nine-E |url=https://www.nhc.noaa.gov/data/tcr/EP092018_Nine-E.pdf |publisher=National Hurricane Center |access-date=26 June 2020 |date=24 August 2018 |archive-url=https://web.archive.org/web/20181006235553/https://www.nhc.noaa.gov/data/tcr/EP092018_Nine-E.pdf |archive-date=6 October 2018 |url-status=live }}

A disturbance began generating thunderstorms as it traveled across northern South America. The system entered the Eastern Pacific Ocean on July 25, and a low-pressure trough formed on the next day to the south of Central America and Mexico. The trough moved westward for several days before a passing Kelvin wave improved the environment; this allowed the trough's convection to gradually become more organized. A tropical depression spawned by 12:00 UTC on July 31, about {{convert|805|mi|km|abbr=on}} south-southwest of the southern tip of the Baja California peninsula. The depression strengthened into Tropical Storm Hector about 12 hours later, at 00:00 UTC on August 1.{{cite report |last1=Berg |first1=Robbie |last2=Houston |first2=Sam |last3=Birchard |first3=Thomas |title=Tropical Cyclone Report: Hurricane Hector |url=https://www.nhc.noaa.gov/data/tcr/EP102018_Hector.pdf |publisher=National Hurricane Center and Central Pacific Hurricane Center |access-date=6 July 2020 |date=1 July 2019 |archive-url=https://web.archive.org/web/20181028225606/https://www.nhc.noaa.gov/data/tcr/EP102018_Hector.pdf |archive-date=28 October 2018 |url-status=live }}

Hector was steered westward during the next several days. The storm was located over warm sea surface temperatures, fueling a 30-hour period of rapid intensification. Hector reached its initial peak on August 2 at 18:00 UTC as a {{convert|90|kn|mph km/h|abbr=on|round=5|sortable=on|order=out}} Category 2 hurricane. Shortly after, northerly shear abraded the northern eyewall of the hurricane before intensification resumed later on August 3. While about {{convert|1,680|mi|km|abbr=on}} west-southwest of the southern tip of the Baja California peninsula, Hector became a Category 3 major hurricane around 00:00 UTC on August 4. After entering the Central Pacific Ocean, Hector tracked west-northwest. Hector peaked on August 6 at 18:00 UTC as a high-end Category 4 hurricane with winds of {{convert|135|kn|mph km/h|abbr=on|round=5|sortable=on|order=out}} and a pressure of {{convert|936|mbar|inHg|abbr=on|sigfig=4}}. The storm's movement gradually shifted westward over the next few days. During this time, lower sea surface temperatures and ocean heat content as well as mid-level dry air caused Hector to gradually weaken into a low-end Category 3 storm. The storm began to intensify again on the next day as a result of improving environmental conditions. Hector reached its secondary peak as a {{convert|120|kn|mph km/h|abbr=on|sortable=on|round=5|order=out}} Category 4 hurricane at 18:00 UTC on August 10. Afterward, Hector tracked towards the west-northwest and later northwest. Southerly shear imparted by an upper-level low caused gradual weakening over the next few days. Hector weakened into a tropical storm around 00:00 UTC on August 13. The storm crossed the International Date Line over 12 hours later, entering the western Pacific Ocean.

Hector approached several islands on its journey through the Central Pacific Ocean, prompting the issuance of tropical storm watches and warnings for islands in Papahānaumokuākea Marine National Monument as well as Johnston Atoll. Overall, the impact to land was minimal; high surf was reported along the southern shores of Hawaii's Big Island and several dozen people were rescued on Oahu.{{cite news |title=Hurricane Hector Passing Hundreds of Miles South of Hawaiian Islands |url=http://www.staradvertiser.com/2018/08/08/weather-updates/hector-passing-south-of-hawaii-island-as-it-tracks-westward/ |work=Star Advertiser |access-date=12 August 2018 |date=8 August 2018 |archive-url=https://web.archive.org/web/20180812114549/http://www.staradvertiser.com/2018/08/08/weather-updates/hector-passing-south-of-hawaii-island-as-it-tracks-westward/ |archive-date=12 August 2018 |url-status=live }}{{cite news |title=Dozens Rescued from South Shore Waters as Hector Kicks Up Surf |url=http://www.hawaiinewsnow.com/story/38852194/hector-pushes-south-shore-surf-to-advisory-levels |work=Hawaii News Now |date=9 August 2018 |access-date=12 August 2018 |archive-url=https://web.archive.org/web/20180812083123/http://www.hawaiinewsnow.com/story/38852194/hector-pushes-south-shore-surf-to-advisory-levels |archive-date=12 August 2018 |url-status=live }} During Hector's track across the Eastern Pacific, it spent more consecutive days as a major hurricane than any other storm.{{cite tweet|title=Philip Klotzbach on Twitter|website=Twitter|date=11 August 2018|access-date=11 August 2018|user=philklotzbach|number=1028117823069900800|author=Philip Klotzbach}}

A tropical wave left the western coast of Africa on July 26 with minimal convection. The wave moved across the tropics and the Caribbean Sea before traversing Central America and entering the Eastern Pacific Ocean on August 4. Despite its close proximity to the larger disturbance which later became Hurricane John, the system rapidly organized into a tropical depression by 18:00 UTC, {{convert|230|mi|km|abbr=on|round=5}} south-southeast of Puerto Ángel, Mexico. The larger disturbance imparted northwesterly wind shear, uncovering the low-level center and preventing further intensification for multiple hours. Despite the shear, a central dense overcast soon developed near the depression's center. The system was upgraded into Tropical Storm Ileana around 12:00 UTC on August 5. Warm sea surface temperatures allowed Ileana to strengthen further as it tracked west-northwest, just off the southwestern coast of Mexico. Ileana reached its peak intensity at 12:00 UTC on August 6 with winds of {{convert|65|mph|km/h}} and a pressure of {{convert|998|mbar|inHg|abbr=on|sigfig=4}}, while located {{convert|115|mi|km|abbr=on|round=5}} southwest of Acapulco. A combination of disruption from Hurricane John located to the west, as well as the Sierra Madre mountains, caused the storm's structure to decay over the next day. Ileana was absorbed into John's outer bands around 12:00 UTC on August 7, just off the coast from Cabo Corrientes, Mexico.{{cite report |last1=Avila |first1=Lixion |title=Tropical Cyclone Report: Tropical Storm Ileana |url=https://www.nhc.noaa.gov/data/tcr/EP112018_Ileana.pdf |publisher=National Hurricane Center |access-date=8 July 2020 |date=9 November 2018 |archive-url=https://web.archive.org/web/20190329025230/https://www.nhc.noaa.gov/data/tcr/EP112018_Ileana.pdf |archive-date=29 March 2019 |url-status=live }}

Tropical Storm Ileana's close proximity to the Mexican coast prompted the issuance of tropical cyclone watches and warnings. Ileana impacted multiple states, causing damaging floods and eight deaths.

An enervated tropical wave departed from the western coast of Africa on July 25. It then traveled westward across the tropical Atlantic, with most of its convection located within the ITCZ until it arrived at South America on July 30. The wave entered the Eastern Pacific two days later and convection drastically increased as a result of the active portion of the Madden–Julian oscillation. An area of low pressure formed on August 4 and became more organized over the day. A tropical depression formed around 12:00 UTC on August 5, about {{convert|335|mi|km|abbr=on|round=5}} south-southwest of Manzanillo, Mexico. The depression then strengthened into Tropical Storm John about 12 hours later as it traveled along the edge of a mid-level ridge, which was located over Mexico. A period of rapid intensification ensued as a result of John being located in a favorable environment of low wind shear, warm sea surface temperatures, and a high quantity of mid-level moisture. John peaked on August 7 at 18:00 UTC as a Category 2 hurricane with winds of {{convert|95|kn|mph km/h|abbr=on|round=5|sortable=on|order=out}} and a pressure of {{convert|964|mbar|inHg|abbr=on|sigfig=4}}, while it approached Socorro Island. A combination of increasing northwesterly wind shear and cooling sea surface temperatures caused John to fall below hurricane strength on August 9. Convection quickly dissipated near the center of the cyclone, causing it to be downgraded to a post-tropical system by 12:00 UTC on August 10, approximately {{convert|345|mi|km|abbr=on|round=5}} west-southwest of Punta Eugenia, Mexico. The remnants continued northwestward and later eastward, before opening into a trough of low-pressure around 18:00 UTC on August 13, about {{convert|405|mi|km|abbr=on|round=5}} west of Punta Eugenia.{{cite report |last1=Blake |first1=Eric |title=Tropical Cyclone Report: Hurricane John |url=https://www.nhc.noaa.gov/data/tcr/EP122018_John.pdf |publisher=National Hurricane Center |access-date=26 June 2020 |date=20 November 2018 |archive-url=https://web.archive.org/web/20190115075747/https://www.nhc.noaa.gov/data/tcr/EP122018_John.pdf |archive-date=15 January 2019 |url-status=live }}

A tropical wave departed from the western coast of Africa on July 22 and traveled quickly across the Atlantic Ocean and the Caribbean Sea. The wave remained without convection until it entered the Caribbean Sea and moved over South America from July 27–29. Convection began to increase overland before the wave crossed into the Eastern Pacific on July 29–30. Continuing westward, the system slowly organized over the next several days, exhibiting intermittent convection and improving cloud cover. Deep convection increased near the system's center on August 6, resulting in the formation of a tropical depression by 18:00 UTC. The depression strengthened into Tropical Storm Kristy six hours later, approximately {{convert|1,035|mi|km|abbr=on}} west-southwest of the southern tip of the Baja California peninsula. During August 7, Kristy became embedded within deep-layer easterlies affiliated with a subtropical ridge which was located to the northeast; this steered the storm westward. The storm continued to increase in organization because it was located within a favorable environment of warm sea surface temperatures and low wind shear. An upper-level low located to the northwest imparted northwesterly wind shear and dry air, causing Kristy to weaken slightly late on August 7.

Hurricane John eroded the subtropical ridge on August 8, causing Kristy to track towards the northwest. The storm resumed strengthening on the same day as wind shear decreased. Kristy peaked on August 10 at 06:00 UTC with {{convert|60|kn|mph km/h|abbr=on|round=5|sortable=on|order=out}} winds and a pressure of {{convert|991|mbar|inHg|abbr=on|sigfig=4}}. The cyclone maintained this intensity for around 12 hours before wind shear increased once more and sea surface temperatures cooled. This caused Kristy to rapidly weaken to a tropical depression by 12:00 UTC on August 11. While the storm lost most of its convection as it weakened, it still produced bursts of convection. Kristy was downgraded to a remnant low on August 12 at 12:00 UTC after having been devoid of convection. The remnants then traveled westward as a swirl of low-level clouds before dissipating on August 13.{{cite report |last1=Latto |first1=Andrew |last2=Pasch |first2=Richard |title=Tropical Cyclone Report: Tropical Storm Kristy |url=https://www.nhc.noaa.gov/data/tcr/EP132018_Kristy.pdf |publisher=National Hurricane Center |access-date=26 June 2020 |date=6 March 2019 |archive-url=https://web.archive.org/web/20190508201132/https://www.nhc.noaa.gov/data/tcr/EP132018_Kristy.pdf |archive-date=8 May 2019 |url-status=live }}

A tropical wave departed from the western coast of Africa on July 31 and traveled westward across the Atlantic Ocean with limited thunderstorm activity. The wave entered the Pacific Ocean on August 8 and became more organized by August 11, however, development was significantly impeded after convection became sporadic. A low-pressure area developed on August 13 and gained banding features as it strengthened. A tropical depression spawned around 00:00 UTC on August 15, about {{convert|1,075|mi|km|abbr=on}} southwest of the southern tip of the Baja California peninsula. At that time, the depression was tracking west-southwest under the influence of a subtropical ridge, which was located to the north. Over the next few days, the ridge weakened, allowing for a westward and later west-northwestward movement. The depression strengthened into Tropical Storm Lane by 12:00 UTC on August 15.{{cite report |last1=Beven |first1=John |last2=Wroe |first2=Derek |title=Tropical Cyclone Report: Hurricane Lane |url=https://www.nhc.noaa.gov/data/tcr/EP142018_Lane.pdf |publisher=National Hurricane Center and Central Pacific Hurricane Center |access-date=8 July 2020 |date=16 December 2019 |archive-url=https://web.archive.org/web/20191215115624/https://www.nhc.noaa.gov/data/tcr/EP142018_Lane.pdf |archive-date=15 December 2019 |url-status=live }}

Soon after, a period of rapid intensification commenced as Lane entered a favorable environment of warm sea surface temperatures, low wind shear, and moist air. Lane became a hurricane by 00:00 UTC on August 17 and reached its initial peak as a {{convert|140|mph|km/h}} Category 4 major hurricane by 12:00 UTC on the next day. The cyclone began to weaken after entering the Central Pacific due to moderate southwesterly wind shear imparted by an upper-level trough located near the Hawaiian Islands. Lane continued slightly north of west after it bottomed out as a Category 3 storm on August 19. Wind shear decreased by midday August 20, allowing Lane to intensify once more. The storm peaked around 06:00 UTC on August 22 as a Category 5 hurricane with winds of {{convert|160|mph|km/h}} and a pressure of {{convert|926|mbar|inHg|abbr=on|sigfig=4}}; this intensity made Lane the fifth storm to achieve Category 5 status in the Central Pacific in recorded history. Over the next few days, Lane weakened as it tracked north-northwest into a region of high wind shear. The cyclone moved around the western edge of a mid-level ridge, shifting its track northward; at its closest point to the state of Hawaii, Lane was about {{convert|150|mi|km|abbr=on|round=5}} away from most islands. The cyclone weakened below Category 3 status early on August 24 and then rapidly weakened into a tropical storm by 06:00 UTC on August 25. The storm then turned westward, away from the Hawaiian Islands, while continuing to weaken. Lane fell to tropical depression status by 12:00 UTC on August 26, and became a tropical storm again a day later despite the shear. Lane weakened into a remnant low by 00:00 UTC on August 29, while {{convert|185|mi|km|abbr=on|round=5}} north-northeast of Johnston Atoll. The remnants traveled northward and dispersed 12 hours later.

Hurricane Lane warranted the issuance of tropical cyclone watches and warnings for the Hawaiian Islands as it remained in close proximity to them for multiple days. Although the core of Lane remained off-shore, the hurricane dropped a record {{convert|58|inch|mm|abbr=on|sigfig=4}} in Akaka Falls State Park on Hawaii's Big Island.

A tropical wave departed from the western coast of Africa on August 17. It then moved westward across the Atlantic Ocean with minimal convection until it crossed over Central America, entering the Eastern Pacific Ocean. Convection began to increase during the next few days, but this trend was hampered by strong northeasterly wind shear. The system produced sporadic convection until September 8, when thunderstorm activity became continuous. A tropical depression formed around 06:00 UTC on September 8, approximately {{convert|680|mi|km|abbr=on}} south-southwest of the southern tip of the Baja California peninsula. The system intensified into Tropical Storm Paul by 00:00 UTC on September 9. The storm traveled westward before turning northwest as it rounded the southwestern edge of a mid-level ridge, which was located over Central Mexico. Paul intensified slightly, peaking at 18:00 UTC with winds of {{convert|45|mph|km/h}} and a pressure of {{convert|1002|mbar|inHg|abbr=on|sigfig=4}}.

By September 10, Paul began to be affected by an unfavorable environment of dry air, wind shear, and cooling sea surface temperatures. This caused the storm to weaken into a tropical depression by 06:00 UTC on September 11. The depression's convection dispersed later in the day, resulting in the system being downgraded to a remnant low around 00:00 UTC on September 12 while it was about {{convert|1,035|mi|km|abbr=on}} west of the southern tip of the Baja California peninsula. A low-level ridge located north of the remnants caused them to return to a westward motion for a couple of days, before a high-pressure system located over the Central Pacific caused them to quickly turn southwestward. The system became elongated and dissipated by 00:00 UTC on September 15.{{cite report |last1=Zelinsky |first1=David |title=Tropical Cyclone Report: Tropical Storm Paul |url=https://www.nhc.noaa.gov/data/tcr/EP182018_Paul.pdf |publisher=National Hurricane Center |access-date=30 June 2020 |date=4 October 2018 |archive-url=https://web.archive.org/web/20181116085405/https://www.nhc.noaa.gov/data/tcr/EP182018_Paul.pdf |archive-date=16 November 2018 |url-status=live }}

A tropical wave departed from the western coast of Africa on August 29 and traveled across the tropical Atlantic before reaching the Pacific Ocean around September 6–7. The wave then meandered south of Mexico for around a week. Around the same time, a mid-level trough, which was moving southward, sent moisture into the region. This allowed a surface trough to develop in a north to south orientation over Baja California Sur and the Gulf of California. Initially quite disorganized, thunderstorm activity gathered around a circulation center on September 19, causing a tropical depression to spawn around 12:00 UTC, just off the coast of Loreto, Mexico. This made the system the first tropical cyclone to form in the Gulf of California in recorded history. Tropical Depression Nineteen-E moved mainly northward and reached its peak intensity by 18:00 UTC with winds of {{convert|35|mph|km/h}} and a pressure of {{convert|1002|mbar|inHg|abbr=on|sigfig=4}}. Wind shear and land interaction inhibited further intensification before the cyclone made landfall between Guaymas and Ciudad Obregón on the Sonoran coast, around 03:00 UTC on September 20. The depression dissipated by 06:00 UTC, about {{convert|60|mi|km|abbr=on|round=5}} inland.{{cite report |last1=Berg |first1=Robbie |title=Tropical Cyclone Report: Tropical Depression Nineteen-E |url=https://www.nhc.noaa.gov/data/tcr/EP192018_Nineteen-E.pdf |publisher=National Hurricane Center |access-date=22 July 2020 |date=29 November 2018 |archive-url=https://web.archive.org/web/20181201005300/https://www.nhc.noaa.gov/data/tcr/EP192018_Nineteen-E.pdf |archive-date=1 December 2018 |url-status=live }}

A low-level gyre located over Central America, which was also associated with the formation of Hurricane Michael in the Caribbean Sea, contributed to the genesis of Tropical Storm Tara. During the period of October 7–10, the disturbance moved into the Gulf of Tehuantepec, after which convection increased. The system then traveled west-northwest over the next several days, parallel to the western coast of Mexico. The system's convection then increased in organization, resulting in the genesis of a tropical depression at approximately 12:00 UTC on October 14, around {{convert|185|mi|km|abbr=on|round=5}} southeast of Manzanillo, Mexico. The nascent depression turned from the west-northwest to the north-northwest as it tracked through a weakness in a trough located over northern Baja California and a mid-level high located over the Gulf of Mexico.

Despite the presence of easterly wind shear, the system became a tropical storm around 06:00 UTC on October 15, while located about {{convert|110|mi|km|abbr=on|round=5}} south-southeast of Manzanillo, Mexico. The cyclone continued to intensify and peaked at 00:00 UTC on October 16 with winds of {{convert|65|mph|km/h}} and a pressure of {{convert|995|mbar|inHg|abbr=on|sigfig=4}}. Steering currents around Tara significantly weakened, almost halting the cyclone's forward motion. A combination of land interaction and increasing southeasterly wind shear caused weakening to commence. Tara opened into a trough just west of Manzanillo around 00:00 on October 17 and dissipated soon after.{{cite report |last1=Pasch |first1=Richard |title=Tropical Cyclone Report: Tropical Storm Tara |url=https://www.nhc.noaa.gov/data/tcr/EP222018_Tara.pdf |publisher=National Hurricane Center |access-date=1 July 2020 |date=28 March 2019 |archive-url=https://web.archive.org/web/20190507030447/https://www.nhc.noaa.gov/data/tcr/EP222018_Tara.pdf |archive-date=7 May 2019 |url-status=live }}

A tropical wave departed from the western coast of Africa on October 6 and traveled westward, arriving at Central America on October 16. Soon after, convection formed along the monsoon trough near the wave. Convection increased and gradually organized over the next few days. A tropical depression formed on October 19 around 06:00 UTC, around {{convert|90|mi|km|abbr=on|round=5}} west-southwest of Puerto San José, Guatemala. Located within a favorable environment, the nascent depression quickly became better organized, developing banding features around its center. This led to the development of Tropical Storm Vicente by 18:00 UTC on the same day. During the course of the day, the cyclone tracked northwestward at around {{convert|6|mph|km/h|abbr=on}}, while it was also very close to the Guatemalan shore. Vicente began traveling west-northwest on October 20, just off the coast of southeastern Mexico. Vicente peaked at 18:00 UTC with winds of {{convert|50|mph|km/h}} and a pressure of {{convert|1002|mbar|inHg|abbr=on|sigfig=4}}, while less than {{convert|115|mi|km|abbr=on|round=5}} off the Mexican coast.{{cite report |last1=Latto |first1=Andrew |last2=Beven |first2=John |title=Tropical Cyclone Report: Tropical Storm Vicente |url=https://www.nhc.noaa.gov/data/tcr/EP232018_Vicente.pdf |publisher=National Hurricane Center |access-date=23 July 2020 |date=10 April 2019 |archive-url=https://web.archive.org/web/20190420033856/https://www.nhc.noaa.gov/data/tcr/EP232018_Vicente.pdf |archive-date=20 April 2019 |url-status=live }}

During the overnight, Vicente began tracking westward. Dry air intrusion caused the tropical storm to weaken on October 21 as it traveled south of west. The dry air abated on October 22, allowing for some re-intensification. Outflow from Hurricane Willa, which was located to the northwest, produced northerly wind shear, which caused Vicente to weaken to a tropical depression by 06:00 UTC on October 23. Vicente made landfall near Playa Azul in Michoacán around 13:30 UTC and dissipated by 18:00 UTC after interacting with land.

Vicente brought torrential rainfall to southern Mexico, peaking at over {{convert|300|mm|in|order=flip|abbr=on}} in the state of Oaxaca.{{cite map |title=Precipitación acumulada (mm) del 20 al 23 de octubre de 2018 por el tormenta tropical Vicente |url=https://smn.conagua.gob.mx/tools/RESOURCES/com_mapas_lluvias/Vicente-2018.png |website=gob.mx |publisher=Conagua |language=es |access-date=12 March 2019 |archive-date=19 August 2020 |archive-url=https://web.archive.org/web/20200819190751/https://smn.conagua.gob.mx/tools/RESOURCES/com_mapas_lluvias/Vicente-2018.png |url-status=live }} Twenty-seven neighborhoods were flooded in Morelia, Michoacán;{{cite news |last1=Tinoco |first1=Miguel Garcia |title=Inundan intensas lluvias 30 colonias de Morelia, Michoacán |url=https://www.excelsior.com.mx/nacional/inundan-intensas-lluvias-30-colonias-de-morelia-michoacan/1273243 |access-date=28 March 2020 |work=Excelsior |publisher=22 October 2018 |language=es |archive-url=https://web.archive.org/web/20200328210146/https://www.excelsior.com.mx/nacional/inundan-intensas-lluvias-30-colonias-de-morelia-michoacan/1273243 |archive-date=28 March 2020 |url-status=live }} hundreds of homes were inundated throughout several neighborhoods after flooding {{convert|1|m|ft|abbr=on|order=flip}} deep occurred.{{cite news |title=La tormenta tropical Vicente causa inundaciones en Morelia, Michoacán |url=https://psn.si/tormenta-tropical-michoacan/2018/10/ |publisher=PSN En Linea |access-date=28 March 2020 |language=es |date=22 October 2018 |archive-url=https://web.archive.org/web/20200328205123/https://psn.si/tormenta-tropical-michoacan/2018/10/ |archive-date=28 March 2020 |url-status=live }} Heavy rainfall caused flooding and landslides in Oaxaca, leaving 13 people dead.{{cite news|author=Jaque|language=es|newspaper=Regeneración|date=26 October 2018|access-date=26 October 2018|title=Aumenta cifra de muertos por lluvias en Oaxaca, suman 13|url=https://regeneracion.mx/aumenta-cifra-de-muertos-por-lluvias-en-oaxaca-suman-13/|archive-url=https://web.archive.org/web/20181101015349/https://regeneracion.mx/aumenta-cifra-de-muertos-por-lluvias-en-oaxaca-suman-13/|archive-date=1 November 2018|url-status=live}} Roadways in the state suffered severe damage after dozens of landslides occurred.{{cite news |author1=Government of Oaxaca |title=Atienden carreteras afectadas por la tormenta tropical Vicente |url=https://oaxaca.quadratin.com.mx/atienden-carreteras-afectadas-por-la-tormenta-tropical-vicente/ |publisher=Quadratin |access-date=31 March 2020 |language=es |date=27 October 2018 |archive-date=19 August 2020 |archive-url=https://web.archive.org/web/20200819190755/https://oaxaca.quadratin.com.mx/atienden-carreteras-afectadas-por-la-tormenta-tropical-vicente/ |url-status=live }}{{cite news |last1=Torres |first1=Humberto A. |title=Decenas de derrumbes impiden comunicación en comunidades de Oaxaca |url=https://imparcialoaxaca.mx/oaxaca/236860/decenas-de-derrumbes-impiden-comunicacion-en-comunidades-de-oaxaca/ |access-date=31 March 2020 |language=es |date=27 October 2018 |work=El Imparcial de Oaxaca |archive-url=https://web.archive.org/web/20190803232700/http://imparcialoaxaca.mx/oaxaca/236860/decenas-de-derrumbes-impiden-comunicacion-en-comunidades-de-oaxaca/ |archive-date=3 August 2019 |url-status=live }}{{cite news |last1=Hernandez |first1=Carlos Alberto |title=Trabaja SCT en 6 tramos carreteros y 30 caminos rurales de Oaxaca |url=https://imparcialoaxaca.mx/oaxaca/237126/trabaja-sct-en-6-tramos-carreteros-y-30-caminos-rurales-de-oaxaca/ |access-date=31 March 2020 |work=El Imparcial de Oaxaca |date=28 October 2018 |language=es |archive-url=https://web.archive.org/web/20190919021804/http://imparcialoaxaca.mx/oaxaca/237126/trabaja-sct-en-6-tramos-carreteros-y-30-caminos-rurales-de-oaxaca/ |archive-date=19 September 2019 |url-status=live }} Flood waters swept away cars, created a sinkhole,{{cite news |last1=Laguna |first1=Raul |title=Tormenta tropical golpea Huatulco y Pochutla en Oaxaca |url=https://imparcialoaxaca.mx/costa/233973/tormenta-tropical-vicente-golpea-huatulco-y-pochutla/ |access-date=31 March 2020 |language=es |date=21 October 2018 |work=El Imparcial de Oaxaca |archive-url=https://web.archive.org/web/20190601005054/http://imparcialoaxaca.mx/costa/233973/tormenta-tropical-vicente-golpea-huatulco-y-pochutla/ |archive-date=1 June 2019 |url-status=live }} and inundated dozens of homes and businesses.{{cite news |last1=Jimenez |first1=Elfego |title=Costa Chica de Oaxaca afectada por la Iluvia |url=https://imparcialoaxaca.mx/costa/233974/costa-chica-de-oaxaca-afectada-por-la-lluvia/ |access-date=31 March 2020 |work=El Imparcial de Oaxaca |date=21 October 2018 |language=es |archive-url=https://web.archive.org/web/20190601024240/http://imparcialoaxaca.mx/costa/233974/costa-chica-de-oaxaca-afectada-por-la-lluvia/ |archive-date=1 June 2019 |url-status=live }}{{cite news |title=Tormenta tropical 'Willa' se forma frente a Colima;

A tropical wave departed from the western coast of Africa on October 2 and moved across the tropical Atlantic with minimal convection. The wave arrived at Central America on October 15 and entered the Pacific Ocean on the next day. Convection formed around the wave on October 17; a low-pressure system developed in association with the wave early on October 18. Thunderstorm activity continued to coalesce, and a tropical depression formed by 00:00 UTC on October 20, approximately {{convert|265|mi|km|abbr=on|round=5}} south of Manzanillo, Mexico. The system tracked west-northwest and northwest as it continued to organize. An increase in convection and the formation of a central dense overcast resulted in the depression being upgraded to Tropical Storm Willa by 12:00 UTC on the same day, about {{convert|290|mi|km|abbr=on|round=5}} south-southwest of Manzanillo. A favorable environment along with Willa's smaller size allowed the cyclone to rapidly intensify for nearly two days. Willa reached hurricane intensity by 06:00 UTC on October 21 and became a major hurricane around 18:00 UTC. Willa peaked as a Category 5 hurricane on October 22 at 06:00 UTC with winds of {{convert|160|mph|km/h}} and a pressure of {{convert|925|mbar|inHg|abbr=on|sigfig=4}}, while located {{convert|195|mi|km|abbr=on|round=5}} south-southwest of Cabo Corrientes, Mexico.{{cite report |last1=Brennan |first1=Michael |title=Tropical Cyclone Report: Hurricane Willa |url=https://www.nhc.noaa.gov/data/tcr/EP242018_Willa.pdf |publisher=National Hurricane Center |access-date=24 July 2020 |date=2 April 2019 |archive-url=https://web.archive.org/web/20190410230420/https://www.nhc.noaa.gov/data/tcr/EP242018_Willa.pdf |archive-date=10 April 2019 |url-status=live }}

After peaking, a combination of cooling sea surface temperatures and an eyewall replacement cycle caused Willa to steadily weaken. The hurricane's eye increased sixfold in size between Willa's peak intensity and the start of October 23. After the replacement cycle ended later that day, the now-Category 3 hurricane tracked northeastward. Around 01:20 UTC on October 24, Willa made landfall near Palmito del Verde, Sinaloa with {{convert|115|mph|km/h}}. Strong southwesterly shear along with the mountainous terrain of Mexico caused Willa to rapidly decline in intensity; the cyclone was a mid-grade tropical storm around 06:00 UTC, while located only {{convert|10|mi|km|abbr=on|round=5}} southeast of Durango, Mexico. The storm dissipated six hours later and sent remnant moisture into southern Texas and Louisiana.

Hurricane Willa necessitated the issuance of tropical cyclone watches and warnings along the southwestern coast of Mexico. As a precautionary measure, over 200,000 people were evacuated from coastal regions in advance of the storm.{{cite news |title=Nayarit en alerta roja por huracán 'Willa' |url=https://www.diariodemexico.com/nayarit-en-alerta-roja-por-huracan-willa |work=Diario de México |access-date=1 August 2019 |language=es |date=23 October 2018 |archive-url=https://web.archive.org/web/20190801021847/https://www.diariodemexico.com/nayarit-en-alerta-roja-por-huracan-willa |archive-date=1 August 2019 |url-status=live }} Willa brought winds up to {{convert|115|mph|km/h}} to the region where it made landfall and torrential rainfall to multiple states; rainfall peaked at {{convert|15.39|in|mm|abbr=on|sigfig=3}} in San Andrés Milpillas, Nayarit.

A tropical wave moved off of the western coast of Africa on October 17 and traveled westward across the tropics and the Caribbean Sea with limited thunderstorm activity. The wave moved over Central America on October 26 and later into a cyclonic gyre that extended over a large portion of the Eastern Pacific on October 31. A passing Kelvin wave fueled an increase in convection along the wave, leading to the formation of a low-pressure system. Over the next couple of days, associated convection continued to increase and organize. A tropical depression spawned at 12:00 UTC on November 2, about {{convert|520|mi|km|abbr=on|round=5}} southwest of Manzanillo. The nascent depression tracked towards the east-northeast between a mid-level ridge which was located to the southeast and a mid- to upper-level trough which was located to the north and northwest. Despite being located in a region of high southwesterly wind shear, disparate upper-level flows allowed the depression to intensify into Tropical Storm Xavier by 00:00 UTC on November 3. The tropical storm continued to gradually strengthen over the next day and a half. Xavier reached its peak intensity at 12:00 UTC on November 4 with winds of {{convert|65|mph|km/h}} and a pressure of {{convert|995|mbar|inHg|sigfig=4|abbr=on}}, while around {{convert|130|mi|km|abbr=on|round=5}} southwest of Manzanillo.

At its closest position to the coast, Xavier was only {{convert|90|mi|km|abbr=on|round=5}} southwest of Manzanillo. Meanwhile, the storm turned northward and subsequently entered a region of dry mid-level air and more powerful southwesterly wind shear. This caused Xavier to quickly weaken; the low-level center completely detached from the storm's convection by 12:00 UTC on November 5. Xavier was downgraded to a post-tropical cyclone by 00:00 UTC on November 6. The remnants traveled west-northwest and later west-southwest while continuing to weaken. The post-tropical system opened up into a trough by 00:00 UTC on November 9, while located around {{convert|345|mi|km|abbr=on|round=5}} west-southwest of Socorro Island.{{cite report |last1=Brown |first1=Daniel |title=Tropical Cyclone Report: Tropical Storm Xavier |url=https://www.nhc.noaa.gov/data/tcr/EP252018_Xavier.pdf |publisher=National Hurricane Center |access-date=5 July 2020 |date=8 February 2019 |archive-url=https://web.archive.org/web/20190328164819/https://www.nhc.noaa.gov/data/tcr/EP252018_Xavier.pdf |archive-date=28 March 2019 |url-status=live }}

An upper-level low absorbed the remnants of Hurricane Lane to the west-northwest of Hawaii on August 29.{{cite tweet|author=National Weather Service Office in Honolulu, Hawaii|user=NWSHonolulu|date=31 August 2018|access-date=2 September 2018|title=Thanks for pointing this out.

Afterwards, 96C gradually began to weaken, while accelerating northward into colder waters. The system weakened into an extratropical low on September 3 and was absorbed by a larger extratropical storm in the Bering Sea the next day.

Storm names

The following list of names was used for named storms that formed in the North Pacific Ocean east of 140°W during 2018.{{cite web|archive-url=https://web.archive.org/web/20181127012731/https://www.nhc.noaa.gov/aboutnames.shtml|url=http://www.nhc.noaa.gov/aboutnames.shtml|title=Tropical Cyclone Names|publisher=National Hurricane Center|archive-date=November 27, 2018|access-date=November 27, 2018|url-status=deviated}} This was the same list used for the 2012 season, as no names were retired after that season.{{cite web|title=Tropical Cyclone Naming History and Retired Names|url=https://www.nhc.noaa.gov/aboutnames_history.shtml|publisher=National Hurricane Center|location=Miami, Florida|access-date=March 7, 2024}} The name Vicente was used for the first time in 2018. The name Willa had previously been used under the old naming convention. No names were retired from the list following that season, and it was used again for the 2024 season.

For storms that form in the North Pacific from 140°W to the International Date Line, the names come from a series of four rotating lists. Names are used one after the other without regard to year, and when the bottom of one list is reached, the next named storm receives the name at the top of the next list. One named storm, listed below, formed within the area in 2018. It was given the last name on List{{nbh}}4, completing the cycle begun 36 years earlier, when the first name on List{{nbh}}1 was used during the 1982 season.{{cite web|website=cyclingweather.org|title=Reaching the End of the List|date=September 27, 2018|url=http://cyclingweather.org/2018/09/reaching-the-end-of-the-list/|access-date=March 7, 2024}}{{cite news|last=Mattos|first=Shelby|title=Here are the possible hurricane names for the 2023 season in the Central North Pacific|date=June 13, 2023|url=https://www.kitv.com/weather/hurricane-center/here-are-the-possible-hurricane-names-for-the-2023-season-in-the-central-north-pacific/article_eef33bae-0a2f-11ee-b076-633172bb92f6.html|publisher=KITV|location=Honolulu, Hawaii|access-date=March 7, 2024}} Named storms in the table above that crossed into the area during the season are noted (*).

Season effects

This is a table of all of the tropical cyclones that formed in the 2018 Pacific hurricane season. It includes their name, duration (within the basin), peak classification and intensities, areas affected, damage, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2018 USD.
