Hot. When winter comes where I live, the wilds are numb, the days are darkest cold seeps into your very bones no matter what you wear, and every action you make is resisted by frigid needles even indoors. You don't want to take showers even with boiling hot water, because afterwards your wet hair and body feel even worse the moment you step out. The outdoor wind leaves your ears numb, forces your eyes shut and sometimes blows strongly enough to push bikes around, not to mention how it messes with cars.
If I were in a game, ice or possibly wind would be my elemental weakness. Being too hot to me feels closer to simply being tired. You can fix it with a swim, a shower, stripping down to a T-shirt and shorts, or just going to the basement.
