This May will probably be most remembered for the number of thunderstorms affecting the area. I recorded an unprecedented (in my memory) four consecutive days of thunderstorms.
It was also warm with a couple of days making the top 10 of hottest days since 1959. The mean temperature finished 15.1C, 2C warmer than average, the warmest May for seven years and the 8th= warmest since 1797.
Rainfall at 65.5mm was 128 per cent of average and slightly drier than last year.
Some 244hrs of sunshine were recorded, 134 per cent of average, making it the sunniest May for 7 years, and the 11th sunniest since 1881.
Spring finished with a mean temp of 11C, 0.8C above average, 1C cooler than last year. Rainfall at 181.9mm, was 135 per cent of average, making it the wettest spring for 10 years. Sunshine of only 411.2 hours made it the dullest spring since 2006.
The warmest day occurred on the 7th with 28.1C.
The wettest day occurred on the 29th with 29.8mm falling during a prolonged thunderstorm.
Air frosts: 0, Ground frosts: 0
This summer in east London is looking average with little to write home about weatherwise.
