Monthly summary April 2009

The start to April was dry and warm but by the 6th pressure was dropping and there followed cloudy and wet days, particularly over the Easter weekend, excepting the Monday, which was glorious. The 15th gave us the warmest day with a maximum of 19.2°C but the following day gave us the wettest with a total of 21.5mm – a third of the rainfall for the whole month. However, as an anticyclone settled over the country we then experienced a dry and very warm period from the 18th to the 23rd. The remainder of the month was cloudy and wet, daytime maxima were close to or above the average but followed by cool nights with air frost on the 28th (-1.1°C) and 28th (-0.9°C).

The rainfall of 68.5mm was 112% of the long-term average. This was the third warmest April I have recorded with a mean of 9.72°C, which is 1.4°C above the long-term average – 1987 was 9.73°C and 2007 was 11.41°C.
