Another very regionally unequal month. Here are the temp, rain and sun maps vs 1981-2010 mean:
Even vs 1961-90 averages large parts of the North and West were below normal
So a cool, wet and dull month for a large swathe of Britain, but a slightly warmer, drier and sunnier month than average across the far South and East, with Kent and Essex on balance the winners.
Considering how much worse the average weather is in the North and West anyway, this must have been a truly dire month there. Northern Ireland in particular seems to have been uniformly cool, wet and very dull. It felt meh enough in London to be honest. Here's the actual sunshine hours to illustrate the point:
