Precipitation in Ireland decreased to 1172.22 mm in 2024 from 1405.51 mm in 2023. This dataset includes a chart with historical data for Ireland Average Precipitation.

The amount of monthly rainfall in Northern Ireland varies from year to year. During the period in consideration, the lowest rainfall levels were recorded in April 2021 at just **** millimeters. Meanwhile, the most rainfall occurred in February 2020, when ***** millimeters fell. In that same month, there were **** rain days recorded, an unusually high number for February. A rain day is when there is a total of 1 mm or more of rain in a day. Seasonal rainfallSince 2010,********has been on average the wettest season in Northern Ireland. In 2023, however, ****** was the wettest season, with roughly *** mm of rainfall. That year, winter was the driest season, with *** mm of rainfall. Regional rainfallWhen compared to the rest of the UK, Northern Ireland receives less rain than both Scotland and Wales, but more than England. In 2024, the country experienced****** mm of rainfall. In comparison, Scotland and Wales received ***** and ******mm, respectively. This is due to the Scottish Highlands high levels of rain and Wales’ location in comparison to the Atlantic Ocean.

On average, autumn and winter are the wettest seasons in Northern Ireland. During the period in consideration, rainfall peaked at****** millimeters in the winter of 2016. In 2025, winter rainfall totals came to ***** millimeters, far below the annual average rainfall in winter since 2011.

Ireland IE: Average Precipitation in Depth data was reported at 1,118.000 mm/Year in 2014. This stayed constant from the previous number of 1,118.000 mm/Year for 2012. Ireland IE: Average Precipitation in Depth data is updated yearly, averaging 1,118.000 mm/Year from Dec 1962 (Median) to 2014, with 12 observations. The data reached an all-time high of 1,118.000 mm/Year in 2014 and a record low of 1,118.000 mm/Year in 2014. Ireland IE: Average Precipitation in Depth data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Ireland – Table IE.World Bank: Land Use, Protected Areas and National Wealth. Average precipitation is the long-term average in depth (over space and time) of annual precipitation in the country. Precipitation is defined as any kind of water that falls from clouds as a liquid or a solid.; ; Food and Agriculture Organization, electronic files and web site.; ;

Ireland: Precipitation, mm per year: The latest value from 2021 is 1118 mm per year, unchanged from 1118 mm per year in 2020. In comparison, the world average is 1168 mm per year, based on data from 178 countries. Historically, the average for Ireland from 1961 to 2021 is 1118 mm per year. The minimum value, 1118 mm per year, was reached in 1961 while the maximum of 1118 mm per year was recorded in 1961.

This factor takes into account the amount and frequency of precipitation in the study area. Annual average precipitation is fairly uniform across the pilot area and was assigned a value of 0.2. The average number of rainy days for this pilot is 225, which results in a low intensity value for for precipitation and an overall low reduction of protection ‘P’ score overall

1 km gridded estimates of daily and monthly rainfall for Great-Britain and Northern Ireland (together with approximately 3000 km2 of catchment in the Republic of Ireland) from 1890 to 2019. The rainfall estimates are derived from the Met Office national database of observed precipitation. To derive the estimates, monthly and daily (when complete month available) precipitation totals from the UK rain gauge network are used. The natural neighbour interpolation methodology, including a normalisation step based on average annual rainfall, was used to generate the daily and monthly estimates. The estimated rainfall on a given day refers to the rainfall amount precipitated in 24 hours between 9am on that day until 9am on the following day. The CEH-GEAR dataset has been developed according to the guidance provided in BS 7843-4:2012.

This dataset provides a continuous monthly rainfall series for the Island of Ireland commencing in January 1711 and running to December 2016. It draws upon diverse sources including weather diaries and early observations. The early record has been quality assured (so far as is possible), through comparison with other long term observational records and climate reconstructions for the regions of the British Irish Isles.

Ireland IE: Droughts, Floods, Extreme Temperatures: Average 1990-2009: % of Population data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Ireland – Table IE.World Bank: Land Use, Protected Areas and National Wealth. Droughts, floods and extreme temperatures is the annual average percentage of the population that is affected by natural disasters classified as either droughts, floods, or extreme temperature events. A drought is an extended period of time characterized by a deficiency in a region's water supply that is the result of constantly below average precipitation. A drought can lead to losses to agriculture, affect inland navigation and hydropower plants, and cause a lack of drinking water and famine. A flood is a significant rise of water level in a stream, lake, reservoir or coastal region. Extreme temperature events are either cold waves or heat waves. A cold wave can be both a prolonged period of excessively cold weather and the sudden invasion of very cold air over a large area. Along with frost it can cause damage to agriculture, infrastructure, and property. A heat wave is a prolonged period of excessively hot and sometimes also humid weather relative to normal climate patterns of a certain region. Population affected is the number of people injured, left homeless or requiring immediate assistance during a period of emergency resulting from a natural disaster; it can also include displaced or evacuated people. Average percentage of population affected is calculated by dividing the sum of total affected for the period stated by the sum of the annual population figures for the period stated.; ; EM-DAT: The OFDA/CRED International Disaster Database: www.emdat.be, Université Catholique de Louvain, Brussels (Belgium), World Bank.; ;

The year with the greatest number of rain days was 2000 when ***** days had at least * mm of rain. England is the driest country in the UK England is on average the driest country in the United Kingdom. In 2024, the country recorded an annual rainfall of **** mm. After England, Northern Ireland is the country that receives the least amount of rainfall across the UK. Wettest regions in Britain Despite Cardiff being the wettest city in the United Kingdom according to the Met Office, Scotland had received on average the largest volume of annual rainfall in the past 10 years. The northern and western regions of the UK – where rainfall is arriving from the Atlantic – tend to be the wettest in the country.

Rainfall sensors are currently deployed around the Burrishoole catchment to ensure maximum spatial coverage of rainfall variation. Data measured are mm of rain. Data coverage is for Furnace Newport Co. Mayo. Rainfall data collected since 1996. Rainfall data has been collected via tipping buckets which are used for the observations and measurements of rainfall. Data collected supports Met Eireann climate and meteorology analysis of rain over time periods. Data collected by the Marine Institute Newport Facility team in association with Met Eireann, Irelands meteorological service. Data has been collected regularly (e.g. daily) and is 100% complete for the period since the rainfall gauges deployed.
