The mean for July in east London was 18.4C, 0.1C below the 1981-2010 average and the coolest for 12 years.

Rainfall of 67.1mm was 154% of average, 3mm less than last July. Sunshine at 177.3 hours was 92% of average. Duller than average but not as dull as last July.

A largely uneventful month with an absence of thunder and lightning.

As thought months ago with ENSO moving toward neutral August should be the month with the best chance of any heat records being broken.

A look at the mean temperature shows how much the climate has warmed since the period 1961-90. Though the mean last month was 1.3C down on the previous 10 years it was actually 0.7C warmer than 1961-90.

9am air pressure was largely below average until the final third of the month, coinciding with the arrival of more summer-like weather.

Here’s a few extremes for the month of August across the capital.
