Something I mentioned to my Wife who was getting fed up with the cool
and wet weather of this spring was that it's a good sign for a better
summer. I then just stumbled across this from Philip Eden quoting
similar years which include 1975, 1976 and 1987 which I think were
probably some of the warmest summer months this century in the UK

Keith 1975, 1976 I agree but 1987 I'm not so sure, certainly wasn't
here!
