About the UV index in Tromsø
Tromsø sits at 69.7° N, in the northern hemisphere. Today's UV peaks at 3.1: the "moderate" band, which uvlevel.net treats as caution for unprotected skin at the worst hour.
This far from the equator, UV is only a real concern for a few months around June and July. For the rest of the year, especially around December and January, the sun stays too low in the sky to build meaningful UV even at solar noon.
