Often enough that when people go skiing in the mountains around there, they bring along suntan lotion.
How about in winter? :-)
I'd say skiing is predominantly a winter activity...
Hey, we're talking about Norway - it's pretty far north - I wasn't 100% sure :-)
The sun doesn't mind the northerly location. It's only 0.01% extra distance from its point of view ;)
Seriously, you can get a terrible sunburn if you don't take care of your face. A couple of days of direct sun plus reflections via the snow surface, and boom.
The cold, dry wind rushing past your face can't help either. Rough conditions for skin.
I have gotten the worst sunburns of my life while skiing. North does not equal not sunny. :)
Well, here in North Dakota you get sunny weather quite a lot in the winter and in Manitoba it is about the same. In fact, the local sunglass stores do more business in winter than in summer. It looks like their weather would be fine for this.
