In many places it was the sunniest December recorded, with many places having twice the average (with more sumshine than some very dull Augusts). The south coast did best for sunshine; totals included 119.8 hours at St. Helier (Jersey) , 118.9 at Weymouth, 115.3 at Torquay, and 115.1 at Bognor Regis. It was the driest December since 1991, with the England and Wales total only about half the expected total. After a mild start, with 16.1C at Nantmor on the 11th, becoming very anticyclonic, with pressure peaking at 1046 mbars over Scotland around the 16th. A cold end.
