Very wet first two weeks in the south and east. Some severe thunderstorms at the end of the month, and some flooding in central Scotland. There were 113 mm of rain in 24 hours at Penistone (near Barnsley) on the 30th. Hence although it was a very wet month, most of the rain fell in the first 12 and last 2 days; hence parts of the SE had no rain at all in between these dates. Mean temperatures were slightly beneath average. The beginning of the month was quite cool, but there was a short heatwave near the end of the month before the thundery breakdown right at the end. In this heatwave, 32.6C was reached at Northolt in London on the 29th (the highest July temperature for 6 years). With such disturbed weather overall it was quite a dull month (the dullest for 10 years, in fact). Coltishall (Norfolk) had only 13 hours sunshine up to the 10th.
