25°C here today. The average maximum for the month is now 18.8°C, which so far puts this April close to the average for June. The nights have generally been cooler than you'd expect for June, but even then the lowest I've recorded is 5.5°C. I've known Aprils since we lived here with inches of snow and minimum temps of about -6°C. When we did the Solstice Warty last June the temperature dropped to about 3°C where we were, on Salisbury Plain. It was bitter.
The Met Office gave the maximum in East England as 25.4, in Santon Downham, Norfolk. Having said that, twice in 3 days they've had Shoebury as the wettest, with 0.2mm rain. I'm bloody sure there hasn't been any. It's only 4 miles form here and we haven't had a cloud that I've noticed.
