Monthly Report for May 2005 at Pollard's Hill Weather Station, Surrey

It was the driest May in Pollards Hill history (However, If I'd been here in 1989 that particular May I very much suspect would have been drier)

I also registered my hottest May maximum temperature ever on the 27th. The warm weather came too late to prevent temperatures over the 31 days being a little down on May's average.

The cool spell continued well into the 2nd and 3rd weeks of the month, but saw some pleasant sunshine despite struggling temperatures. There were a few wintry showers on the 16th as northerly winds brought Arctic air and a maxima of only 11.6°C along with some damaging ground frosts. From the 18th it turned warmer; everyday from the 18th - 31st had a maxima above 17.3°C, reaching above 20°C on the 5 days from the 24th to 28th.
