Sunniest week in Bariloche and Chalten

Hello... on average, which is the sunniest week of the year in Bariloche and Chalten? Thanks

In Bariloche, the first two weeks on January are more likely to be sunny... maybe the whole of January on a good Summer... though with the weather down in Patagonia, YOU NEVER KNOW! It can snow, rain, be sunny all in a day...
