The climate of Ireland is mild, humid and changeable with abundant rainfall and a lack of temperature extremes. Ireland's climate is defined as a temperate oceanic climate, or Cfb on the Köppen climate classification system, a classification it shares with most of northwest Europe.{{cite journal |author1=Peel, M.

As Ireland is downwind of a large ocean, it is considerably milder in winter than other locations at the same latitude, for example Newfoundland in Canada or Sakhalin in Russia. The Atlantic [[Thermohaline circulation|
overturning circulation]], which includes ocean currents such as the North Atlantic Current and Gulf Stream, releases additional heat over the Atlantic, which is then carried by the prevailing winds towards Ireland giving, for example, Dublin a milder winter climate than other temperate oceanic climates in similar locations.McCarthy, G. D., Gleeson, E. and Walsh, S. (2015) The influence of the Ocean on the Climate of Ireland. Weather. 70, 8, 242–245, http://onlinelibrary.wiley.com/doi/10.1002/wea.2543/abstract
The prevailing wind blows from the southwest, breaking on the high mountains of the west coast. Rainfall is therefore a particularly prominent part of western Irish life, with Valentia Island, off the west coast of County Kerry, getting almost twice as much annual rainfall as Dublin on the east ({{convert|1400|mm|in|1|abbr=on|disp=or}} vs. {{convert|714|mm|in|1|abbr=on|disp=or}}).
January and February are the coldest months of the year, and mean daily air temperatures fall between {{convert|4|and|7|C|F|1}} during these months. July and August are the warmest, with mean daily temperatures of {{convert|14|to|16|C|F|1}}, whilst mean daily maximums in July and August vary from {{convert|17|to|18|C|F|1}} near the coast, to {{convert|19|to|20|C|F|1}} inland. The sunniest months are May and June, with an average of five to seven hours sunshine per day.{{cite web|url=http://www.met.ie/climate/sunshine.asp|title=Sunshine in Ireland|access-date=23 January 2008|publisher=Met Éireann|archive-url=https://web.archive.org/web/20171218093952/https://www.met.ie/climate/sunshine.asp|archive-date=18 December 2017}} Though extreme weather events in Ireland are comparatively rare when compared with other countries in the European continent, they do occur. Atlantic depressions, occurring mainly in the months of December, January and February, can occasionally bring winds of up to {{convert|160|km/h|mph|0|abbr=on|disp=or}} to Western coastal counties, with the winter of 2013/14 being the stormiest on record.Matthews, T., C.

Temperature
Ireland experiences a lack of temperature extremes compared to other areas at similar latitudes. There is regional variation, with inland areas being cooler in winter and warmer in summer than their coastal counterparts.
The warmest areas are found along the southwest coast. Valentia Island has the highest average temperature, at 10.9 °C.
The coldest areas are found inland. Mullingar has the lowest average temperature, at 9.3 °C.
The highest temperature ever recorded in Ireland was 33.3 °C at Kilkenny Castle, on 26 June 1887. The lowest temperature was –19.1 °C at Markree Castle on 16 January 1881.
Six of the warmest ten years in Ireland have occurred since 1990.{{Cite web|url=http://www.epa.ie/climate/communicatingclimatescience/whatisclimatechange/whatimpactwillclimatechangehaveforireland/|title=What impact will climate change have for Ireland|last=Environmental Protection Agency|date=2017|website=EPA}} Due to climate change, it is estimated that the temperatures will rise everywhere by up to 3.4 degrees by the end of the century.{{cite journal|last1=Murphy|first1=Conor|last2=Fealy|first2=Rowan|date=2010|title=Climate Change Impacts for Ireland Part 2: Changes in Key Climatic Variables|url=http://eprints.maynoothuniversity.ie/2671/1/CM_Climate_Impacts_Pt2.pdf|journal=Geographical Viewpoint|volume=38|page=31|access-date=11 January 2018}}
Extreme heat and cold are both rare throughout the country. Summer temperatures exceeding 30 °C are rare, usually only occurring every few years (2022, 2021, 2018, 2016, 2013, 2006, 2005, 2003, 1995, 1990, 1989, 1983, 1976 and 1975 are recent examples), although they commonly reach the high 20s most summers. Severe freezes occur only occasionally in winter, with temperatures below –10 °C being very uncommon in the lowlands and temperatures below freezing uncommon in many coastal areas. However, temperatures in the Wicklow Mountains are said to reach –10 °C annually.{{citation needed|date=June 2015}}

=Frost=
Air frost occurs frequently in the winter, with most areas seeing over 40 days of air frost every year. In northern areas, air frost occurs on average 10.2 days every January, the month in which air frost occurs most frequently.{{cite web|url=http://www.metoffice.gov.uk/climate/uk/averages/19712000/areal/n_ireland.html|title=N Ireland 1971-2000 averages|access-date=17 May 2008|publisher=Meteorological Office|url-status=dead|archive-url=https://web.archive.org/web/20070927031233/http://www.metoffice.gov.uk/climate/uk/averages/19712000/areal/n_ireland.html|archive-date=27 September 2007}} In the Sperrins and the Glens of Antrim air frost occurs around 80 days a year.{{cite web|url=http://www.metoffice.gov.uk/climate/uk/averages/19712000/daf/17.gif |title=Days of Air Frost 1971-2000 |publisher=Meteorological Office |access-date=18 May 2008 |url-status=dead |archive-url=https://web.archive.org/web/20070705082009/http://www.metoffice.gov.uk/climate/uk/averages/19712000/daf/17.gif |archive-date= 5 July 2007 }} The pattern is similar with ground frost, with on average around 100 days of ground frost in the lowlands and over 140 in the mountains.{{cite web|url=http://www.metoffice.gov.uk/climate/uk/averages/19712000/dgf/17.gif|title=Days of Ground Frost 1971-2000|publisher=Meteorological Office|access-date=18 May 2008|url-status=dead|archive-url=https://web.archive.org/web/20070109064830/http://www.metoffice.gov.uk/climate/uk/averages/19712000/dgf/17.gif|archive-date=9 January 2007}} The number of frost days in Ireland have declined massively over the past decade. The largest season decrease has been known to take place in winter.
Frost is rarer along the coast, in urban areas and also in western and southern areas.
Roches Point, County Cork receives the fewest days with air frost, with an average of 7.0 days with air frost recorded annually.{{Cite web|url=http://www.met.ie/climate/rochespoint.asp|title=Met Éireann - Roches Point (30 Year Averages)|access-date=14 December 2019}}

Sunshine
File:SummerCloud (Cropped).JPG
The sunniest months are May and June. During these months sunshine duration averages between 5 and 6½ hours per day over most of the country. The southeast gets the most sunshine, averaging over 7 hours a day in early summer. December is the most overcast month, with average daily sunshine ranging from about 1 hour in the north to almost 2 hours in the southeast. Over the year as a whole, most areas get an average of between 3¼ and 3¾ hours of sunshine each day. Irish skies are completely covered by cloud roughly half of the time.
The sunniest part of the island is the southeast coast. Rosslare, County Wexford was historically the sunniest area, however, the station was closed by Met Éireann in 2007.{{Cite web |date= |title=Climatology details for station Rosslare, IRELAND and index SS: Sunshine duration |url=http://eca.knmi.nl/utils/calcdetail.php?seasonid=0&periodid=1981-2010&indexid=SS&stationid=2137 |archive-url=https://web.archive.org/web/20200211224335/http://eca.knmi.nl/utils/calcdetail.php?seasonid=0&periodid=1981-2010&indexid=SS&stationid=2137 |archive-date=2020-02-11 |access-date=2024-06-19 |website=eca.knmi.nl}} The sunniest station throughout the 1981 to 2010 period was Ballyrichard HSE in Arklow, County Wicklow, which received an average of 4.41 hours of sunshine per day.

The cloudiest (i.e. least sunny) parts of the island are generally the west and northwest of the country. Over the 1971-2000 averaging period, Claremorris, County Mayo was the cloudiest station, receiving just 1,072 hours of sunshine per year. From 1981 to 2010, Birr, County Offaly, in the Midlands, was the most cloudy (overcast) station, receiving on average 3.2 hours of sunshine per day, considerably less than the stations at Malin Head in the north or Belmullet in the west.{{Cite web |date= |title=Climatology details for station Birr, IRELAND and index SS: Sunshine duration |url=http://eca.knmi.nl/utils/calcdetail.php?seasonid=0&periodid=1981-2010&indexid=SS&stationid=120 |archive-url=https://web.archive.org/web/20200130104037/http://eca.knmi.nl/utils/calcdetail.php?seasonid=0&periodid=1981-2010&indexid=SS&stationid=120 |archive-date=2020-01-30 |access-date= |website=eca.knmi.nl}}
Inland areas tend to receive less sunshine than coastal areas due to the convective development of clouds over land. Cloud develops because of vertical air currents caused by thermal heating of the ground.{{cite web | url = http://www.met.ie/climate-ireland/sunshine.asp | title = Sunshine and Solar Radiation | publisher = Met Éireann | archive-url = https://web.archive.org/web/20180217071303/http://www.met.ie:80/climate-ireland/sunshine.asp | archive-date = 17 February 2018}}

Precipitation
=Precipitation=
Rainfall is the most common form of precipitation on the island, and is extremely common throughout Ireland, although some parts of the west coast receive twice as much rain as the east coast. Rainfall in Ireland normally comes from Atlantic frontal systems which travel northeast over the island, bringing cloud and rain. Most of the eastern half of the country has between {{convert|750|and|1000|mm|in|1|abbr=on}} of rainfall in the year. Rainfall in the west generally averages between {{convert|1000|and|1250|mm|in|1|abbr=on}}. In many mountainous districts rainfall exceeds {{convert|3000|mm|in|1|abbr=on}} per year. The wettest months almost everywhere are December and January. April is the driest month generally, but in many southern parts, June is the driest.
The average number of "wet days" (days with more than {{convert|1|mm|in|3|abbr=on}} of rain) ranges from about 151 days a year along the east and southeast coasts, to about 225 days a year in parts of the west.
The wettest weather station is Glanagimla, Leenane, Co. Galway, which averages {{convert|2874.59|mm|in|2|abbr=on}} rain per year.{{Cite web|url=https://www.met.ie/climate/available-data/historical-data|title=Historical Data|publisher=Met Éireann|access-date=11 November 2020}}{{nonspecific|date=November 2020}} The wettest synoptic weather station is Valentia Island, which receives {{convert|1430.1|mm|in|2|abbr=on}} of rain per year, on average.{{Cite web|url=https://www.met.ie/climate-ireland/1981-2010/valentia.html|title=Valentia 1981–2010 averages|website=www.met.ie|access-date=14 December 2019}}
The driest weather station is at Ringsend, Co. Dublin, which receives {{convert|683|mm|in|2|abbr=on}} of rain per year, on average.
The weather station with the highest number of "wet days" is Belmullet, with 193 days per year,{{Cite web|url=http://www.met.ie/climate/belmullet.asp|title=Met Éireann - Belmullet (30 Year Averages)|access-date=14 December 2019}} while the station with the lowest number of "wet days" is Dublin Airport, with 128 days per year.
==Rainfall records==
- The driest year recorded in Ireland was 1887, with {{convert|356.6|mm|in|2|abbr=on}} of rain recorded at Glasnevin, County Dublin.
- The longest drought in Ireland occurred in Limerick between 3 April 1938 and 10 May 1938 (37 days).
- The greatest monthly total was {{convert|790.0|mm|in|2|abbr=on}}; recorded at the Cummeragh Mountains, County Kerry, in October 1996.
- The greatest annual total was {{convert|3964.9|mm|in|2|abbr=on}}; recorded at Ballaghbeena Gap in 1960.
- The greatest daily total was {{convert|243.5|mm|in|2|abbr=on}}; recorded at Cloone Lake, County Kerry, on 18 September 1993.
=Snowfall=
Severe cold weather is uncommon in Ireland with the majority of winter precipitation coming in the form of rain, although hills and mountainous regions in the country can commonly see up to 30 days of snowfall annually: the Wicklow Mountains region sometimes experiences 50 or more days of snowfall each year. Most low-lying regions of the island only see a few days of lying snow per year (from December to March inclusive), or may see no snow at all during some winters.
However, there are preparations for snow and ice, including the distribution of grit, salt, and other snow-treatable minerals. In late 2011, the Irish Government set up "Winter-Ready", in order to prepare the country for such severe weather.{{cite web|title=News|url=http://www.merrionstreet.ie/index.php/2011/11/shatter-launches-winter-ready-campaign/?cat=3|work=Shatter launches Winter Ready campaign|publisher=Irish Government News Service|access-date=1 December 2011}}
Due to its variability (which is mainly because of the influence of the Atlantic Ocean, Gulf Stream and North Atlantic Drift, as well as Ireland's northerly latitude and vulnerability to Siberian/Arctic winds) Ireland's weather during the winter months is difficult to predict. The aforementioned factors make both extremely low temperatures and relatively mild temperatures possible.
The snowiest weather station is Clones, County Monaghan, which receives, on average, 18 days of snow and/or sleet per year. Of these, 6.2 days have snow lying at 09:00.{{Cite web|url=https://www.met.ie/climate-ireland/1981-2010/clones.html|title=Clones 1978–2007 averages|website=www.met.ie|access-date=4 December 2020}} The least snowy weather station is Valentia Island, County Kerry; which receives, on average, 5.6 days of snow and/or sleet per year. Of these, 0.8 days have snow lying at 09:00.
=Hail=
Hail, like snow and sleet, is also rare in Ireland; however, it can occur at any time of the year. It is most common in spring during thunderstorms.
Malin Head, County Donegal receives the most hail, with an average of 48.4 days per year.{{Cite web |url=http://www.met.ie/climate/malinhead.asp |title=Met Éireann - Malin Head (30 Year Averages) |access-date=8 May 2008 |archive-url=https://web.archive.org/web/20111009104715/http://met.ie/climate/malinhead.asp |archive-date=9 October 2011 |url-status=dead }}

=Thunderstorms=
Thunderstorms are quite rare in Ireland.{{citation needed|date=February 2016}} They are more likely to happen in late spring, although they can occur at any time of the year.
Cork Airport, County Cork experiences the least thunder; receiving it 3.7 days per year on average.{{Cite web |url=http://www.met.ie/climate/corkairport.asp |title=Met Éireann - Cork Airport (30 Year Averages) |access-date=8 May 2008 |archive-url=https://web.archive.org/web/20080508021517/http://www.met.ie/climate/corkairport.asp |archive-date=8 May 2008 |url-status=dead }}
Valentia Island, County Kerry experiences the most thunder; receiving it 7.1 days per year on average.
Wind
Generally, the coast tends to be windier than inland areas, and the west tends to be windier than the east.
The station with the highest mean wind speed is Malin Head, County Donegal, averaging at {{convert|16.3|kn|km/h mph|abbr=on|lk=in}}. Malin Head also receives the most gale-force winds, recording them on average 66.0 days per year.
The station with the lowest mean wind speed is Kilkenny, County Kilkenny; averaging at {{convert|6.5|kn|km/h mph|abbr=on}}.
The station that records the lowest number of gale-force winds is Birr, County Offaly; recording them on average 1.2 days per year.{{Cite web|url=http://www.met.ie/climate/birr.asp|title=Met Éireann - Birr (30 Year Averages)|access-date=14 December 2019}}
The highest wind speed ever recorded in Ireland was {{convert|103|kn|km/h mph|0|abbr=on}} at Fastnet Lighthouse, County Cork on 16 October 2017.{{Failed verification|date=January 2018}}
Tornadoes are very rare in Ireland, with around less than ten reported every year - mostly in August.{{Cite web|url=https://www.breakingnews.ie/ireland/yesterdays-tornados-almost-unheard-of-372813.html|title=Yesterday's tornados 'almost unheard of'|date=7 August 2008|website=Breaking News|access-date=14 December 2019}}
Fog
Image:Olympus Jan 2003 377-2.jpg
Fog is more common inland and on higher altitudes; mainly during winter and during the morning at times of high pressure.
The foggiest station is that at Cork Airport, County Cork, which has 99.5 days of fog per year.
The least foggy station is that at Valentia Island, County Kerry, which has 8.9 days of fog per year.
Visibility
Visibility is generally very good, because of the proximity of industry to the coast, allowing breezes to disperse any smog.{{cite web|url=http://www.metoffice.gov.uk/climate/uk/location/nireland/index.html |title=Met Office:Northern Ireland climate |publisher=Meteorological Office |access-date=17 May 2008 |url-status=dead |archive-url=https://web.archive.org/web/20070929092850/http://www.metoffice.gov.uk/climate/uk/location/nireland/index.html |archive-date=29 September 2007 }} Mist and fog often occur, as well as coastal fog in the east,{{cite encyclopedia |url=http://www.britannica.com/eb/article-44640/Northern-Ireland|title=Northern Ireland: Climate |access-date=17 May 2008 |encyclopedia=Encyclopædia Britannica}} but it is generally not long-lasting. However, in winter, it can be slow to clear.
