These final averages use quality controlled data from the UK climate network of observing stations. They show the Met Office's best assessment of the weather that was experienced across the UK during May 1999 and how it compares with the 1961 to 1990 average.

The columns headed 'Anom' (anomaly) show the difference from or percent of the 1961-90 long term average.
