Coming up to 10 years since this absolute awful summer month. The worst feature of this month was the lack of sunshine, for England, Wales and Northern Ireland, as a whole, it was duller than February of the same year. February 2018 was exceptionally sunny granted but August was so dull it was the 9th sunniest month of the year!
February, March, April, September and October were all sunnier than August 2008.
For northern Scotland, it wasn't as bad as the rest of the country, sunshine wise.
Some of the sunshine figures are shocking for a summer month
Hampstead: 97hrs
Wittering: 116hrs
Ross-on-Wye: 126hrs
St Mawgan: 118hrs
Edgbaston: 101hrs
Valley: 86hrs
Woodford: 79hrs

For parts of Scotland Northern Ireland, to add to the extreme dullness, it was also exceptionally wet.

The cloud amounts meant that maxima were suppressed but minima held up. The highest maximum recorded in the UK for the month was 27.5C on the 6th at Faversham
For me, it was a month to forget!
