Here are the reports for 2010 for the Copley sites.
(Averages refer to 1971-2000)

Copley Lead Mill 218metres asl
Temperature °C
Mean maximum 10.9 High 27.2 on 22/05 Low -4.2 on 20/12
Mean minimum 2.7 Low -11.8 on 21/12 High 14.6 on 27/07
Mean screen 6.8

That figure caught my eye. The coldest year in the whole CET record was
1740, with almost exactly that mean: 6.84C. Your figure for Copley shows
the effect that going one or two hundred miles north and a couple of
hundred metres higher has.
