A look at local east London stats shows that six of the last 10 Junes have been warmer than average while half have been much drier than average.
I’ve put together a few top 10s of stats for Wanstead, St James’s Park and Heathrow for the month of June.
Probably most notable from the below values is that recent Junes have been devoid of extreme cool temperatures and rainfall.
Snow has been known to fall in June, in 1975.
Rain is usually most frequent in the last week of the month.
The 10 driest Junes were:
Some UK May values according to TORRO
Hottest: 29th 1957: 35.6C at Camden Square, London. Also Southampton 28th 1976
Coldest: 9th 1955: -5.6C at Dalwhinnie, Highland. Also June 1st and 3rd 1962: Santon Downham, Norfolk
Wettest: 28th 1917: 242.8mm at Bruton, Somerset
In terms of climatology June maxima, considering the 1981-2010 average, shows a gradual increase through the month, though around the 19th to the 21st there is often a dip before a warm end. This would reflect the June Monsoon which occurs every year at 77 per cent probability.
The average rainfall graphic reflects this, showing a four-day wetter spell after the 20th.
