June 2018: driest on record since 1797

This June will probably be most remembered for the lack of rainfall throughout the month. I recorded just 0.7mm of rain over the 30 days – the driest June in a local record going back to 1797, 0.4mm less than the previous driest June in 1925.

A fire on Wanstead Flats on Friday 29th was quickly extinguished thanks to the fire brigade

As I write this the area is now experiencing its 24th day of ‘meteorological drought’ conditions with little prospect of anything heavy anytime soon. The month was in stark contrast to May which saw may downpours associated with thunderstorms.

It was a warm month. The mean temperature finished 18.1C, exactly 2C above average, though slightly down on last June and the 7th= warmest since 1797.

Some 231.4hrs of sunshine were recorded, 130 per cent of average, making it the sunniest May for 8 years, and the 30th sunniest since 1881.

The warmest day occurred on the 25th with 30C.

The wettest day occurred on the 9th with 0.4mm falling.

  1. As you know our fires up here have highlighted how dry it is. I was cycling up on the moors yesterday and I have never seen it so dry. A local quarry normally has a mud bath section even in the height of summer but now looks like a dust bowl. Not hurt my lap time though!
