Monthly Summary
 
A very settled, sunny and warm month. The average temperature was 3.6º above the 71-00
Durham mean. In fact, April 2007 was warmer than an average May. Certainly the warmest
April that I have recorded by far. Also the hottest April temperature was recorded with
23.4ºC on 15th, far warmer than the previous record of 20.9ºC, which was set in 2004.
 
Not only was April excessively warm compared to the average, it was also very dry, with
just 9mm rain recorded during the month, less than 20% of what you would expect. This is
also yet another record set during this month, as it is the driest month that I have ever
recorded.
