Mean temperatures were between 0.5 °C and 1.5 °C above the 1971-2000
normal throughout the UK, with increasing warmth toward the east coast of
England. Rainfall was above normal in north-west England, Northern Ireland
and much of Scotland, with most of north-west Scotland receiving more than
160% of the long-term May average. By contrast, it was drier in southern
England, with East Anglia and the south-east receiving less than 75%. Elsewhere,
rainfall was mostly close to average. Sunshine was generally around normal
in the south-west, Wales, Northern Ireland and parts of northern England
but above average elsewhere; indeed, May was a notably sunny month across
the north and east of Scotland with 150% of normal sunshine in a few spots.
