Temperature Climate of Ireland

Temperature is a key indicator of changes in the climate, measurements and analysis are essential for assessing the affects of climate change. The value of high quality observations to the meteorological and climatological scientific communities cannot be overstated. Historical observations are of particular value since an observation once made in time cannot be retaken, and if observations are not taken we have no way of directly knowing what the past weather and climate were like.

Met Éireann has recorded and stored nearly 9.5 million individual hourly temperature measurements into the National Climate Database between 1939 and 2017. From this observational dataset, and others, analysis is completed to give details of the Rainfall Climate of Ireland.

The moderating influence of the Atlantic on temperatures is felt throughout Ireland. Because of this the country does not experience the same range of temperature extremes that more continental countries achieve throughout the year, with relatively mild winters and cool summers.
