Winter in the GH & PT

Can't find a contour map but Google tells me I'm about 77 ft above sea level. I can see Salisbury cathedral to the SE about 6 miles away, I can hear the planes from Boscombe Down airfield and Porton Down, where they do the microbiological research, is about 2 miles away. It's some 25 miles to the coast. Notwithstanding all that I still think you have a less frosty early season in sunshiny south Wales
