It's odd isn't it. Presumably the difference is due to topography? I am surrounded to some extent or another by highish hills (>300m) all around, Clee Hill, the south Shropshire hills, Welsh hills and the Malverns. I'm not especially high at 93asl. I'm about a mile outside of the village proper, and that is a frost hollow too. Anyway, whatever the reason I am very hapy about it
