Dublin is in a maritime [[temperate]] [[oceanic climate|oceanic]] region according to [[Köppen climate classification]]. Its climate is characterised by cool winters, mild humid summers, and a lack of temperature extremes. [[Met Éireann]] have a number of weather stations in the county, with its two primary stations at [[Dublin Airport]] and [[Casement Aerodrome]].

Annual temperatures typically fall within a narrow range. In [[Merrion Square]], the coldest month is February, with an average minimum temperature of {{convert|4.1|C|F|abbr=on}}, and the warmest month is July, with an average maximum temperature of {{convert|20.1|C|F|abbr=on}}. Due to the [[urban heat island]] effect, Dublin city has the warmest summertime nights in Ireland. The average minimum temperature at Merrion Square in July is {{convert|13.5|C|F|abbr=on}}, similar to [[London]] and [[Berlin]], and the lowest July temperature ever recorded at the station was {{convert|7.8|C|F|abbr=on}} on 3 July 1974.<ref>{{cite web|url=https://www.met.ie/climate/available-data/historical-data|title=Historical Data: DUBLIN (MERRION SQUARE) – Station No. 3923|publisher=Met Éireann|access-date=9 June 2022|archive-date=24 June 2021|archive-url=https://web.archive.org/web/20210624195529/https://www.met.ie/climate/available-data/historical-data|url-status=live}}</ref><ref>{{cite web|url=http://eca.knmi.nl/utils/mapserver/climatology.php#bottom|title=Climatological Information for Merrion Square, Ireland|publisher=European Climate Assessment & Dataset|access-date=8 November 2020|archive-date=30 August 2012|archive-url=https://web.archive.org/web/20120830134927/http://eca.knmi.nl/utils/mapserver/climatology.php#bottom|url-status=live}}</ref> At Dublin Airport, the driest month is February with {{convert|48.8|mm|0|abbr=on}} of rainfall, and the wettest month is November, with {{convert|79.0|mm|0|abbr=on}} of rain on average.

As the prevailing wind direction in Ireland is from the south and west, the Wicklow Mountains create a [[rain shadow]] over much of the county. Dublin's sheltered location makes it the driest place in Ireland, receiving only about half the rainfall of the west coast. [[Ringsend]] in the south of Dublin city records the lowest rainfall in the country, with an average annual precipitation of {{convert|683|mm|0|abbr=on}}. The wettest area of the county is the [[Glenasmole|Glenasmole Valley]], which receives {{convert|1,159|mm|0|abbr=on}} of rainfall per year. As a temperate coastal county, snow is relatively uncommon in lowland areas; however, Dublin is particularly vulnerable to heavy snowfall on rare occasions where cold, dry easterly winds dominate during the winter.<ref>{{cite web |url=http://www.met.ie/climate/temperature.asp |title=Temperature – Climate |publisher=Met Éireann – The Irish Meteorological Service Online |date=2 January 1979 |access-date=20 August 2010 |archive-date=7 January 2019 |archive-url=https://web.archive.org/web/20190107003129/https://www.met.ie/climate/temperature.asp%20 |url-status=live }}</ref>

During the late summer and early autumn, Dublin can experience Atlantic storms, which bring strong winds and torrential rain to Ireland. Dublin was the county worst-affected by [[Hurricane Charley (1986)|Hurricane Charley]] in 1986. It caused severe flooding, especially along the River Dodder, and is reputed to be the worst flood event in Dublin's history. Rainfall records were shattered across the county. Kippure recorded {{convert|280|mm|0|abbr=on}} of rain over a 24-hour period, the greatest daily rainfall total ever recorded in Ireland. The government allocated [[Irish pound|IR£]]6,449,000 (equivalent to US$20.5 million in 2020) to repair the damage wrought by Charley.<ref>{{cite web|date=8 March 1990 |title=Storm and Flood Damage: Motion – Seanad Éireann |publisher=Office of the Houses of the Oireachtas |access-date=26 October 2008 |url=http://historical-debates.oireachtas.ie/S/0124/S.0124.199003080005.html |url-status=dead |archive-url=https://web.archive.org/web/20110607120811/http://historical-debates.oireachtas.ie/S/0124/S.0124.199003080005.html |archive-date=7 June 2011 }}</ref> The two reservoirs at Bohernabreena in the Dublin Mountains were upgraded in 2006 after a study into the impact of Hurricane Charley concluded that a slightly larger storm would have caused the reservoir dams to burst, which would have resulted in catastrophic damage and significant loss of life.
