July did not prove to be the summer month to which we all looked forward. With the mean temperature 2.0C below the long-term average, it was a cool month. This was principally due to depressed daytime temperatures as the nights were close to the long-term average. The mean maximum temperature was not equalled until the 22nd when we experienced a brief spell of days with much sunshine and high temperatures. The hottest day was the 22nd when the thermometer peaked at 28.8C. In contrast, the coldest day was the 2nd when a maximum of only 15.3C was reached.
It was also a very wet month with the total rainfall of 91.6mm being 155% of the long-term average. The wettest day was the 6th with 20.5mm but substantial falls were recorded on the 3rd, 7th and 12th with 11.2mm, 10.6mm and 12.1mm respectively. There were only eleven dry days.
Winds were generally light with the highest gust of 26mph recorded on the 2nd.
Compared with recent years the sunshine was only 95% of the average and solar energy 93%.
There were two days when thunder was heard, on the 6th and 11th. A funnel cloud was observed for quite a time to the north of the town on the 5th.
