This is the second consecutive day with an identifiable Heat Low over southern England. Yesterday's (Sat.) produced a marked westerly here which died out early evening. Today's low is somewhat less marked and there is a light N'ly but I wouldn't bet against a sea breeze from the south coast penetrating as far as here temporarily (40 miles). It does happen from time to time. Max temps on both days 31°C.

Tudor, unless my ageing eyes are deceiving me, a tiny heat low formed
over Exeter this afternoon. I was looking at the satellite images and
you can detect an anti-clockwise rotation to the clump of cloud stuck
over the city.

We're right on the edge of it here and the sky all around is clear. If
it wasn't a heat low then maybe sea breezes were responsible for the
rotation?
