It is very unusual - the dividing line temperature wise is very narrow, correlating closely with the wind direction.
Southend (14 miles away, or 10 miles further north) is reporting 23 with variable winds. Shoeburyness, closer still, 21. Yet here it's 18.6, and the high so far is only 18.8. Winds here are SW'ly, but light.
Meanwhile as with this morning, a few miles south there are more heavy downpours. I do wish some of them would edge just that bit further north, but it's unlikely - the centre of the shallow low is close by.
