Very similar here in Warlingham, not surprisingly, but the overnight max
was even higher, at 16.8°C. This was higher than yesterday's daytime max of
16.4°C but on my 08/20 (clock time) system it won't count. Too bad - one must
stick to the system.
Today's max was(!) 19.8°C at 1245Z but it is now down below 15°C. Nothing
more than windy drizzle and light rain on the front, though. To the lee of
hedges and large trees the ground is dry.
