Climate and climate change

UK actual and anomaly maps

The actual and anomaly maps are based on 5 km grid-point data sets, with the anomaly information referring to the 30-year averaging periods, 1961-1990 and 1971-2000, and 1981-2010.

Maps for the most recent five to six months (including monthly, seasonal and annual maps) are provisional. After six months, all maps are final. A timetable for publication of the climate summaries is available below.

Timing of summaries and statistics

Seasonal and annual maps are only available for: mean daily maximum temp.; mean daily minimum temp.; mean temperature; rainfall and sunshine.

Monthly maps of days of snow lying are available after approximately six months. Monthly maps of days of thunder are not available after December 2010.

Rainfall maps include all precipitation (rainfall, snow and hail).
