So it's not all snow because most of it looks like Cyrodiil? Since we've spent an entire thread congratulating ourselves for discovering this simple fact... what next?
No it isn't. The southern quarter is like Cyrodiil, which in proportions like that isn't going to get annoying as it was in Oblivion. The bigger western half is much like Hammerfell, which we haven't seen yet but for innacurate examples given in
Redguard. A tad more than half is snow and ice, which in and of itself isn't that bad. The Cyrodiil-like climate is the smallest part. Besides, whine enough and they will change the climate so when we play it we whine about how the climate isn't what it was supposed to be in lore so Beth can bang their heads against the wall :banghead: , as seen in Oblivion.
The climate is about 3/16 Cyrodiil-like, 5/16 Hammerfell-like, and 8/16, well, Skyrim-like.
