It was however slightly drier than average in Scotland. Quite wet and cool in the first half, warmer and sunnier in the second. A strong depression early brought north-easterly gales and then heavy rain to the south on the 7-8th. Indeed, in much of the south more than half the month's total; rainfall fell on just the 7th, with up to 30 mm in less than 24 hours across much of the south. This was followed by severe thunderstorms. Wittering, near Peterborough, saw 109 mm in just over 24 hours. It was followed by northerly winds; at Sennybridge the maximum on the 8th did not exceed 10C. There was a warmer spell at the end of the month, with 30C being reached at Heathrow on the 29th. However, the period from the middle of June to the middle of Jully was the worst summer spell since 1981.
