Monthly summary September 2010

September was an unusual month.  I cannot remember when the mean temperatures and total rainfall were almost identical to the long-term averages. The mean maximum was identical at 18.7°C and the mean minimum just 0.2°C below. The total rainfall was 63.0mm compared with the long-term average of 63.6mm. The first 12 days often brought days with glorious sunshine, light breezes and above average maxima with a maximum of 22.6°C on the 10th. With winds veering into a more northerly direction in the middle of the month there were some very cool nights with a minimum of 2.6°C in the early hours of the 18th. The wettest day was the 22nd with 16.9mm. The latter part of September brought depressed maxima combined with windy and wet days.
