After months of darkness, it starts to get brighter.
It is still dark, the snow lies deep, and the lakes are frozen, but the days will be longer and longer. We see blue sky most days. Life returns.
If you are going to visit Norrbotten so wait a month. We think mid-March to mid-April is best when it is beautiful weather, it is possible to do lots of outdoor activities, and it can be a little warmer than in February.
