In general, Europe is not just colder towards the north compared to the south, but it also gets colder from the west towards the east. The climate is more oceanic in the west and less so in the east. This can be illustrated by the following table of average temperatures at locations roughly following the 64th, 60th, 55th, 50th, 45th and 40th latitudes. None of them is located at high altitude; most of them are close to the sea.
