With a CET of 16.1C, it was the warmest June since 1976 (and only 1970, 1950, and 1940 have been warmer in the last century); it was also the sunniest since 1996. Because of a few heavy rainfall events it was slightly wetter than usual in the south, and drier in the NE. It was consistently warmer than average because a persistent region of low pressure over the north Atlantic, leading to frequently southerly winds. In the south there were only two days when the temperature failed to exceed the expected average (and at Heathrow the maximum failed to reach 21C/70F on only one day), but there were only 6 days above 25C. The month started hot, with 26.1C at Lossiemouth, Moray. Thunderstorms during the night of the 1-2 led to local flooding: 60 mm fell at Hastings. The highest temperature was a maximum of 30.5C near Loughborough on the 22nd.
