The month had a cold start as Arctic air swept south, giving snow on the mountains of Scotland, settling above 1000 m. There were also some low temperatures and widespread ground frosts: -1.8C at Redhill (Surrey) early on the 9th, +0.3 and 0.4 C at Benson (Oxon) on the mornings of the 8th and 9th, and 3C at Hurn (Bournemouth) on the 9th. Dry but cloudy and cool first half. There were 54 mm of rain at Newquay on the 5th, with most of that in just three hours. There were some notable thunderstorms midmonth, with 58 mm at Leeming on the 15th (most of it in 3 hours), 4 cms hailstones in Luton, and 70 mm of rain at Coltishall (Norfolk), leading to flooding. There was a heatwave at the end, culminating in 32.2C (just 90F) at Northolt (London) on the 26th, and high temperatures widespread in the south. The minimum in Southampton on the night of the 25-26th was 21C (70F). There was a severe hailstorm in the evening of the 26th in west Kent; the streets looked as though they were covered in snow, and car bonnets were dented. Overall, slightly warmer than average in the SE, but slightly cooler in the NW. In England and Wales, it was the driest and sunniest June since 1996. It was however cloudier than average in the north.
