The 2021 Pacific hurricane season was a moderately active Pacific hurricane season, with above-average activity in terms of number of named storms, but below-average activity in terms of major hurricanes,{{#tag:ref|Hurricanes reaching Category 3 (1-minute sustained winds higher than {{convert|96|kn|mph km/h|order=out}}) on Saffir–Simpson scale are described as major hurricanes,{{cite web|title=Saffir-Simpson Hurricane Wind Scale|url=https://www.nhc.noaa.gov/aboutsshws.php|publisher=National Hurricane Center|location=Miami, Florida|access-date=July 17, 2023}}|group="nb"}} as 19 named storms, 8 hurricanes, and 2 major hurricanes formed in all.{{#tag:ref|The National Hurricane Center 1991-2020 seasonal averages for a Pacific hurricane season are 15 named storms, 8 hurricanes, and 4 major hurricanes.|group="nb"}}{{cite web|last1=Masters|first1=Jeff|last2=Hanson|first2=Bob|title=Category 1 Hurricane Rick poised for a Monday morning landfall in southwestern Mexico|date=October 24, 2021|url=https://yaleclimateconnections.org/2021/10/category-1-hurricane-rick-poised-for-a-monday-morning-landfall-in-southwestern-mexico/|publisher=Yale Climate Connections|location=New Haven, Connecticut|access-date=May 27, 2022}} It also had a near-normal accumulated cyclone energy (ACE). The season officially began on May 15, 2021 in the Eastern Pacific Ocean (east of from 140°W), and on June 1, 2021, in the Central Pacific (from 140°W to the International Date Line) in the Northern Hemisphere. The season ended in both regions on November 30, 2021. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention.{{cite web|date=June 1, 2018|title=Hurricane Season Information|url=https://www.aoml.noaa.gov/hrd-faq/#when-is-hurricane-season|access-date=May 28, 2022|work=Frequently Asked Questions About Hurricanes|publisher=NOAA Atlantic Oceanographic and Meteorological Laboratory|location=Miami, Florida|language=en-US}} However, the formation of tropical cyclones is possible at any time of the year, as illustrated by the formation of Tropical Storm Andres on May 9, which was the earliest forming tropical storm on record in the Eastern Pacific. Conversely, 2021 was the second consecutive season in which no tropical cyclones formed in the Central Pacific.
In June, Tropical Storm Dolores made landfall near the border of the Mexican states of Colima and Michoacán, killing three people and resulting in US$50 million{{refn|All damage totals are valued as of 2021 and in United States dollars, unless otherwise noted.|group="nb"}} in insured losses. Just a week later, Hurricane Enrique paralleled the west coast of Mexico, causing an additional two fatalities and a similar amount of damage. In August, Hurricane Nora made landfall on the state of Jalisco and paralleled the Pacific coast of Mexico until dissipating, resulting in an estimated $100 million in damage and three more deaths. Less than two weeks later, Hurricane Olaf made landfall on Baja California Sur as a Category 2 hurricane. In October, Hurricane Pamela struck Nayarit at Category 1 intensity, leaving four people missing and severe flooding. Later that month, Hurricane Rick struck near the Michoacán-Guerrero border at peak intensity as a strong Category 2 hurricane. Altogether, five systems made landfall in Mexico in 2021, the greatest number since 2018.

Seasonal forecasts
Forecasts include weekly and monthly changes in important factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. According to the National Oceanic and Atmospheric Administration (NOAA), the average hurricane season in the Eastern and Central Pacific between 1991 and 2020 contained approximately 15 tropical storms, 8 hurricanes, and 4 major hurricanes. The NOAA generally classifies a season as above average, average, or below average based on the cumulative ACE index, but occasionally the number of tropical storms, hurricanes, and major hurricanes within a hurricane season is also considered. Factors they expected to reduce activity were near- or below-average sea surface temperatures across the eastern Pacific and the El Niño–Southern Oscillation remaining in the neutral phase, with the possibility of a La Niña developing.
On May 12, 2021, the Servicio Meteorológico Nacional issued its forecast for the season, predicting a total of 14–20 named storms, 7–10 hurricanes, and 4–5 major hurricanes to develop. On May 20, 2021, the National Oceanic and Atmospheric Administration (NOAA) issued their outlook, calling for a below-normal to near-normal season with 12–18 named storms, 5–10 hurricanes, 2–5 major hurricanes, and an accumulated cyclone energy index of 65% to 120% of the median.

In early May, the passage of a convectively-coupled kelvin wave (CCKW) enhanced the eastern Pacific monsoon trough, leading to an area of disturbed weather. This disturbance interacted with a Gulf of Tehuantepec gap wind event, which led to the formation of an ill-defined low-pressure area. Despite a marginal environment of wind shear and dry air, the system slowly organized and developed into a tropical depression around 06:00 UTC on May 9. Six hours later, it intensified into Tropical Storm Andres, becoming the earliest tropical storm on record in the East Pacific basin. Andres maintained peak winds of 40 mph (65 km/h) as it curved north-northwest, and the compounded effects of colder waters and drier air atop moderate wind shear instead caused the system to begin weakening. All associated convective activity dissipated by 06:00 UTC on May 11, when Andres was downgraded to a remnant area of low pressure. The low curved west on May 12 and dissipated later that day.
There are no reports of damage or casualties directly associated with Tropical Storm Andres; however, some other rainstorms associated with Andres produced heavy rainfall in Southwestern Mexico.{{cite web|url=https://www.debate.com.mx/estados/Pronostico-del-clima-de-hoy-se-esperan-lluvias-por-depresion-tropical-UNO-E-del-Pacifico-20210509-0013.html|title=Pronóstico del clima de hoy: se esperan lluvias por depresión tropical UNO-E del Pacífico|author=Óscar Barrón|website=Debate|date=May 9, 2021|access-date=May 9, 2021|language=Spanish}}{{cite web|date=May 9, 2021|title=SE FORMA ANDRES!|url=https://vadenuez.info/wp/se-forma-andres/|access-date=May 9, 2021|website=Noticias Va de Nuez|language=es}} Moisture from the storm caused intense rain and even a hailstorm as far east as the State of Mexico, including in the state's capital, Toluca.

Blanca originated from a tropical wave that crossed Central America on May 27. Shower and thunderstorm activity increased ahead of the wave axis, followed by the formation of a low-pressure area. After further organization, the developed into a tropical depression around 18:00 UTC on May 30. It intensified into Tropical Storm Blanca around 12:00 UTC the next day. Favorable environmental conditions allowed the cyclone to intensify, and it attained peak winds of 60 mph (95 km/h) on June 1 when prominent rainbands wrapped into the center. Thereafter, an upper-level trough off the southwestern United States increased shear over Blanca and injected dry air into the core, resulting in a weakening trend. The storm's low-level circulation became separated from convection, and it degenerated to a remnant low by 00:00 UTC on June 4. The remnants of Blanca, which were previously tracking west-northwest, curved toward the west before dissipating later the next day.{{cite report|author=Brad J.

A trough developed within the Intertropical Convergence Zone (ITCZ) on June 1. It moved west across the eastern Pacific for several days but failed to develop into a tropical cyclone on several occasions, either because it lacked a coherent circulation or because it lacked sustained convection. A burst of thunderstorms resulted in the formation of a well-defined center on June 12, and the system steadily organized over ensuing hours, finally resulting in the formation of a tropical depression by 12:00 UTC that day. Six hours later, the depression intensified into Tropical Storm Carlos to the southwest of Baja California Sur. The surrounding environment was initially favorable for development and allowed the system to reach peak winds of 50 mph (85 km/h) as it curves west-southwest. However, increasing dry air around the storm caused Carlos to gradually lose its convection, which ultimately resulted in its degradation to a remnant low by 12:00 UTC on June 16. The remnant system was reabsorbed into the ITCZ the following day.{{cite report|author=Daniel P.

{{Main|Tropical Storm Dolores (2021)}}
A broad cyclonic gyre over Central America, spawned from the interaction of the monsoon trough and a tropical wave, led to the formation of an area of low pressure south of Mexico on June 16. The low gradually organized and became a tropical depression around 18:00 UTC on June 17 while located about {{convert|195|mi|km|abbr=on|round=5}} south-southwest of Acapulco. The depression became Tropical Storm Dolores within six hours. Ridging over Mexico shifted east as Dolores developed, causing the cyclone to curve to the north-northwest. A favorable environment facilitated its development, and the storm reached peak winds of 70 mph (110 km/h) as it made landfall near San Juan de Alima, Michoacán, around 15:00 UTC on June 19. It harbored a well-defined eyewall at the time, and it is possible that Dolores temporarily surpassed tropical storm intensity. Once inland, though, the system quickly weakened over the high terrain of southwestern Mexico, dissipating around 06:00 UTC on June 20.{{cite report|author=Philippe P. Papin|title=Tropical Cyclone Report: Tropical Storm Dolores|url=https://www.nhc.noaa.gov/data/tcr/EP042021_Dolores.pdf|publisher=National Hurricane Center|date=January 5, 2022|accessdate=January 14, 2022|location=Miami, Florida}}
Dolores produced a wide expanse of {{convert|5|in|mm|abbr=on}} or greater rainfall across southwestern Mexico, including a peak accumulation of {{convert|17.31|in|mm|abbr=on}} in Callejones, Colima. At least 20 municipalities in Michoacán were affected by flooding or uprooted trees, blocking many routes through these communities. In Jalisco, the Marabasco River overflowed its banks, briefly isolating 80 homes. Throughout Guerrero, Michoacán, Colima, and Jalisco, more than 50,000 customers lost power. Overall damage to more than 1,000 structures totaled in excess of $50 million. Three people were killed by lightning, two in Oaxaca and one in Jalisco.

{{main article|Hurricane Enrique (2021)}}
A tropical wave left Africa on June 14 and crossed Central America a week later. The system coalesced as it moved south of Mexico, becoming Tropical Storm Enrique by 12:00 UTC on June 25 since the incipient system was already producing gale-force winds at the time of development. Moderate wind shear initially inhibited the cyclone, but these unfavorable winds slackened late on June 25, allowing the cyclone to begin a 24-hour period of rapid intensification. Enrique intensified into a hurricane around 12:00 UTC on June 26 and reached peak winds of 90 mph (150 km/h) the next morning as it was characterized by a cloud-filled eye. The storm curved north and then bent back northwest, passing within 45 miles (75 km) of the Mexico coastline.

A disturbance of unclear origin was identified over Central America and the far eastern Pacific on July 9. The system progressed westward over the open ocean during the following days, developing into a tropical depression around 00:00 UTC on July 14 and becoming Tropical Storm Felicia six hours later. Felicia immediately underwent rapid intensification, becoming a hurricane by 06:00 UTC on July 15 and a major hurricane 24 hours later. Early on July 17, the system attained peak winds of 145 mph (235 km/h).{{cite report|author=John P.

The cyclone rapidly weakened and degenerated to a remnant low by 18:00 UTC on July 20 while located well east of Hawaii. Low-level wind flow steered the remnant low of Felicia to the west-southwest, and it opened into a trough two days later.

A tropical wave moved off the coast of Africa on July 6 and emerged into the eastern Pacific basin a week later, where the background environment already favored cyclonic spin. Consequently, a disturbance spawned along the wave axis developed into a tropical depression by 00:00 UTC on July 17 and further into Tropical Storm Guillermo within twelve hours. A potent ridge pushed the cyclone west-northwest, while a favorable combination of low wind shear and very warm ocean temperatures allowed it to intensify. Guillermo reached peak winds of 60 mph (95 km/h) on July 18 despite a slightly less organized satellite appearance. Around this time, the storm produced tropical storm-force gusts on Socorro and Clarion islands. After its peak, Guillermo encountered cooler waters and higher wind shear, which ultimately caused it to degenerate to a remnant low by 00:00 UTC on July 20. The low moved faster to the west-southwest before it was absorbed by a trough a day later far away from land.{{Cite report|author=Stacy R.

A parade of tropical waves entered the eastern Pacific in late July. By 12:00 UTC on August 1, one wave spawned a disturbance that had gained sufficient organization to be designated a tropical depression. Moderately wind shear inhibited the newly formed system, and though it intensified into Tropical Storm Ignacio a day later, the system failed to organize beyond that strength as its low-level circulation became separated from associated convective activity. Around this time, the system produced tropical storm-force gusts on Socorro Island. Later on August 2, Ignacio began to succumb to increasingly dry air and cooler waters. It degenerated to a remnant low around 00:00 UTC on August 4, which moved erratically until it dissipated southwest of Baja California twelve hours later.{{cite report|author=John L.

A tropical wave entered the eastern Pacific on August 1, and the resultant disturbance organized into a tropical depression around 12:00 UTC on August 7. The newly formed cyclone swiftly intensified amid very high mid-level moisture and ocean temperatures, becoming Tropical Storm Kevin six hours later and reaching peak winds of 65 mph (100 km/h) on August 8.

Kevin passed near Clarion Island on August 10 as it moved west then west-northwest, producing tropical storm-force gusts there.

A tropical wave moved into the eastern Pacific on August 6, spawning an area of disturbed weather that subsequently became a tropical depression around 06:00 UTC on August 10. It moved generally westward, intensifying into Tropical Storm Linda six hours later and organizing further beyond that point, but temporarily succumbing to some dry air and wind shear. As those factors subsided, Linda strengthened into a hurricane on August 12 and soon began rapidly intensifying over warm ocean waters, a process that culminated in it becoming the season's second and final major hurricane by 18:00 UTC on August 13. The next day, Linda peaked as a Category 4 cyclone with winds of 130 mph (215 km/h). Between August 14–15, the storm underwent an eyewall replacement cycle. Much like Hurricane Felicia, Linda soon acquired characteristics of an annular hurricane, with a 45 mi (75 km) wide eye surrounded by deep, symmetric convection and little additional banding. The hurricane fluctuated in intensity over the next few days as it moved over varying ocean temperatures and through drier air. Late on August 18, Linda progressed over ocean waters cooler than {{convert|26|C|F|abbr=on}}, which led to rapid weakening.

The Atlantic Hurricane Grace struck mainland Mexico as a Category 3 hurricane on August 21. Although that storm's low-level center dissipated over the mountainous terrain of Mexico, its mid-level circulation emerged into the eastern Pacific and soon became encompassed by deep convection. That thunderstorm activity spawned a new surface center separate from Grace's previous one, and further organization of the disturbance led to the formation of Tropical Storm Marty by 00:00 UTC on August 23. The newly christened tropical storm reached peak winds of 45 mph (75 km/h) early on August 23, but it began to weaken shortly thereafter as wind shear increased. Marty moved west as it encountered an increasingly hostile environment of dry air and cooler waters, resulting its degeneration to a remnant low by 06:00 UTC on August 24. Three days later, it dissipated into a trough well to the west-southwest of Baja California Sur.{{cite report|author=Daniel P.

{{main article|Hurricane Olaf (2021)}}
A tropical wave moved off Africa on August 22. It fractured twice over subsequent days, with portions of the original wave axis spawning tropical storms Kate and Mindy in the Atlantic. The southern piece of the wave continued into the East Pacific on September 2, where it led to the formation of a new tropical depression around 18:00 UTC on September 7 about {{convert|230|mi|km|abbr=on}} west-southwest of Manzanillo, Colima. The system drifted toward the northwest in weak steering currents, while favorable environmental parameters allowed it to intensify. The depression became Tropical Storm Olaf around 12:00 UTC on September 8, and Olaf became a hurricane 24 hours later. The cyclone's eye and overall presentation continued to improve into September 10, and Olaf reached its peak as a Category 2 hurricane with winds of 105 mph (165 km/h) at 02:50 UTC that day. It concurrently made landfall near San Jose del Cabo, Baja California Sur. The storm only slowly weakened over land, but this process accelerated as it continued into stable air offshore. It curved west and degenerated to a remnant low around 06:00 UTC on September 11. The low continued in that direction for another day before dissipating.{{cite report|author=Andy S. Latto|title=Tropical Cyclone Report: Hurricane Otto|url=https://www.nhc.noaa.gov/data/tcr/EP152021_Olaf.pdf|publisher=National Hurricane Center|date=January 10, 2022|accessdate=January 10, 2022|location=Miami, Florida}}
As Olaf paralleled the Mexico coastline, it produced rainfall totals up to 4 in (100 mm) across Jalisco, which resulted in localized flooding. One man died there following a mudslide. Rainfall accumulations were generally similar across the Baja California Peninsula, though a peak value of {{convert|9.27|in|mm|abbr=on}} was observed in El Triunfo. Many weather stations near Olaf's landfall location lost power upon the storm's final approach, but widespread tropical storm-force winds were nevertheless recorded. The strong winds damaged hotels, uprooted trees, and downed power lines. More than 190,000 customers across the Baja California Peninsula were without power at the height of the storm. Total damage was estimated at $10 million, primarily focused in La Paz and Los Cabos.

{{main|Hurricane Pamela}}
A tropical wave emerged into the eastern Pacific on October 8, and it swiftly organized into a tropical depression by 06:00 UTC on October 10. The system moved west-northwest, tracking parallel to the Mexico coastline initially after formation, and intensified into Tropical Storm Pamela six hours later.{{cite report|author=John P. Cangialosi|title=Tropical Cyclone Report: Hurricane Pamela|url=https://www.nhc.noaa.gov/data/tcr/EP162021_Pamela.pdf|publisher=National Hurricane Center|date=November 29, 2021|accessdate=December 25, 2021|location=Miami, Florida}} Throughout Pamela's duration, the NHC highlighted the expectation of a potentially major hurricane rapidly intensifying up to the Mexico coastline.{{cite web|author=Stacy R.

It became a hurricane around 06:00 UTC on October 12, weakened thereafter, and regained hurricane strength early the next day. Pamela maintained winds of 75 mph (120 km/h) as it recurved northeast ahead of a broad upper-level trough, and it made landfall at that intensity just north of Mazatlán, Sinaloa, at 12:30 UTC on October 13. Topographical and environmental effects caused Pamela to rapidly dissipate shortly before 00:00 UTC on October 14 over northern Mexico.
Although Pamela made landfall in a remote location, its effects were spread across large portions of northwestern Mexico. Across Colima and Nayarit, widespread rainfall accumulations of {{convert|4|–|8|in|mm|abbr=on}} – with isolated totals up to {{convert|12|in|mm|abbr=on}} – caused widespread flooding.

{{main|Hurricane Rick (2021)}}
A collection of convection formed over Colombia, Panama, and adjacent waters of the Caribbean and East Pacific on October 16. The disturbance moved west without much change in organization until it developed into a tropical depression early on October 22. The system strengthened into Tropical Storm Rick within six hours of formation and continued to intensify amid very favorable environmental conditions as it moved generally north-northwest. Rick became a hurricane early on October 23, around which time the system developed a pinhole eye in microwave imagery. After reaching winds of 90 mph (150 km/h), the system abruptly weakened as its inner core structure eroded. However, the cyclone soon developed a large eye, and it reached a peak intensity of 105 mph (165 km/h) early on October 25. Rick maintained these winds as it made landfall in La Unión de Isidoro Montes de Oca, Guerrero, around 11:00 UTC. The storm weakened rapidly once inland and dissipated before 00:00 UTC on October 26.{{cite report|author=Robbie Berg|title=Tropical Cyclone Report: Hurricane Rick|url=https://www.nhc.noaa.gov/data/tcr/EP172021_Rick.pdf|publisher=National Hurricane Center|date=January 24, 2022|accessdate=January 25, 2022|location=Miami, Florida}}
Rick produced at least 4 in (100 mm) of rain across coastal sections of Guerrero and Michoacán, with a peak accumulation of 11.06 in (281 mm) in Petacalco and Coyuquilla in Guerrero. These rains prompted flash flooding that stranded cars and caused damage throughout the region, even well inland across the state of Morelos where one man was killed in Tepoztlán. Four rivers and streams overrun their banks across Zihuatanejo and Tecpan de Galeana, including the Petatlán River which cut off the Acapulco–Zihuatanejo federal highway. Many large trees were uprooted and some damage occurred to buildings between Ixtapa and Lázaro Cárdenas. Rick prompted the evacuation of 402 people and damaged 1,277 houses across 11 states and 700 municipalities. Nearly 184,000 homes lost power, especially concentrated in the states of Michoacán and Guerrero. Tens of millions worth in damage occurred.

For named storms that form in the Central Pacific Hurricane Center's area of responsibility, encompassing the North Pacific between 140°W and 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. No storms formed within the area in 2021. Named storms in the table above that crossed into the area during the season are noted (*).{{cite report|title=2021 Hurricane Season Summary for the Central Pacific Basin|date=November 28, 2021|url=https://www.weather.gov/media/hfo/2021_HurricaneSeasonSummary.pdf|publisher=NOAA|access-date=January 27, 2024}}
Season effects
This is a table of all of the storms that formed in the 2021 Pacific hurricane season. It includes their name, duration, 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 2021 USD.
