30 Year Averages

The World Meteorological Organization (WMO) recommends that climate averages are computed over a 30 year period of consecutive records. The period of 30 years is considered long enough to smooth out year to year variations. Henceforth Met Éireann will reference 1981 to 2010 as the baseline period for day-to-day weather and climate comparisons. The current WMO global baseline period for use in climate change research is 1961-1990.
