I can hardly believe there can be such a difference over less than 200

I've seen 10C differences between the north & south coasts of Cornwall
on a number of occasions, even in west Cornwall where the distance is
10miles.

I will not allow folk to try and hi-jack this thread unless they can
give me examples of mid-July, no sea breeze and after a long spell of
high pressure.
