Yet people seem to think that it's going to be very temperate once you get away from the areas of mountains, like New York, Canada, or England, and I don't exactly see why since I haven't seen any sources (besides people's speculation) saying that Skyrim will not be very cold and very snowy almost all over. Even everyone's favorite myth about the vampires living under frozen lakes take place in East Skyrim. Mountain lakes, are ironically usually formed by Glaciers so that would probably mean that the were from melted glaciers, and melted glaciers usually don't freeze over permanently, and if they're not in the mountains, then they've gotta be cold. Since what I've read talks about snowy valleys and mountains alike, it seems more likely that it would be at a lower altitude where it would be warmer, but if the lake is frozen over year-round... it's under 32 degrees there year round... which would mean... it snows there year round.
Anyway, that's just the Mountainous East, there's gotta be some foresty-places. The Mountainous South where Bruma's located where there's snow year-round? Well then it's gotta be the North that's warm, except that lore has stated that the seas to Atmora were ice-choked, and if there are snowy mountains and valleys in the East, how could it possibly be warm in the north if Tamriel's in the Northern Hemisphere? And, I'd like to note, that Black Marsh and Elsweyr are Warm Desert/Tropcial climates, which would mean they're probably close to the Tamrielic Equator, and Atmora's to the north, which means that Tamriel's in the Northern Hemisphere, and you'd get colder as you go further north. Bruma's high up, but so are the other mountains to the south that aren't cold. There's also the original Elven inhabitants of Skyrim, the Falmer, who had a coat of white-blue ice over their skin and would obviously need temperatures below the freezing point to keep frozen.
I'm just wondering where people got the idea that most of it isn't snowy and cold, because I haven't found anything to back it up. :shrug:
