Climate averages
Long-term averages
The World Meteorological Organization (WMO) requires the calculation of averages for consecutive periods of 30 years, with the latest covering the 1961–1990 period. However, many WMO members, including the UK, update their averages at the completion of each decade. Thirty years was chosen as a period long enough to eliminate year-to-year variations.
These averages help to describe the climate and are used as a base to which current conditions can be compared. Use the links below to see a selection of station, district and regional averages or UK and regional maps for a wide range of weather elements.
