There were over 300 mm of rain at Shap. As there was a heatwave at the start of the month, and some very warm nights, it was also, perhaps surprisingly, a hot month overall (17.7C CET). There were some heavy thunderstorms at the start of the month. 31.5C was then recorded on the 8th at Northolt. The 8-9th was very warm in the south; at Marham (Norfolk) the minimum was only 21.7C. The 9-11th saw some exceptionally heavy rain in central and southern Scotland and northern England. Aberfeldy saw nearly 150 mm in three days. We tried going to Edinburgh, but everywhere was flooded so we gave up. There was some excep[tionally heavy rain in Cornwall on the 16th (some parts saw 75 mm in 24 hours; and Otterham had 200.4 mm in 24 hours, with 197 mm in 4 hours and nearly 100 mm in an hour) led to exceptionally severe flash-flooding and destruction in the Boscastle region. Heavy rain in central Scotland led to a mudslip on the A85 and A84 near Lochearnhead on the 18th that buried several cars. Lancashire was affected by some very heavy rain on the 19-20th, with flooding: 23 mm fell in an hour early in the morning of the 20th at Hazelrigg. Overall it was the most thundery month since June 1982, and the most thundery August since 1960.
