I'm sure Kev B will have the stats, but I reckon in July we had at least 20 days that saw some rainfall at some point.
Broken record, sure, but all I ask for is the sort of few-week dry & mainly sunny spell with temps into the mid-20's.
My England and Wales summer index (normalised temp, rainfall and sunshine since 1970) shows the following:
April: 120.91 (third highest in series)
May: 153.22 (highest in series)
June: 124.93 (just above average)
July: 126.15 (well below average)
E&W rainfall was 130% of 1971-00 average, and sunshine was 84% of average.
So it was a pretty disappointing July, but mainly in the Midlands, North and West.
