Weather statistics for June show it was a relatively warm but wet start to summer 2019.

Scientists from Rothamsted Research, who collate the data, found rainfall was above average with 70.8mm throughout the month and on one day, 22mm of water came down.

There were 17 days with a spattering of 0.22mm or more, and five days with showers of 5mm or more.

It was also less sunny than expected, with only 92.8 hours of rays recorded from June 1 to 19. Due to a fault, the equipment has not been able to measure sunlight since June 19.

Despite all this, it was warmer than expected. The mean maximum was 19.3C and the mean minimum was 10.2C - above average by 0.16C and 0.41C respectively.

By reaching 32.7C, scorching June 29 can be crowned the hottest day of the month. This is the second warmest day in June since 1878.

The coolest night dropped to 4.9C on June 9 and there were three ground or air frosts.
