When you ski downhill and get off a lift at top station, -30C (or close to it) is not that uncommon and in addition it might blow so that your head is about to fly off and maybe that head is not covered in any fashion because you did not take anything along, trusting some misguided forecast or not reading one. Some extreme weather people complain about in the flats can be bread and butter in skiing. Obviously those who do mountaineering encounter even harsher conditions, but they ask for it, while downhill skiing, at least in Europe where it is priced affordably, would be done by an average Joe.
