Frequently asked questions
What is the UV index in Tromsø today?
Today’s UV index in Tromsø is shown at the top of this page using forecast data from the Norwegian Meteorological Institute.
Is the UV index high in Tromsø?
Tromsø is well north of the Arctic Circle, so the sun stays low in the sky for much of the year. In summer, however, the midnight sun produces continuous daylight, and snow reflection in spring can lead to significant UV exposure.
Do I need sun protection for Northern Lights trips?
The Northern Lights season runs through the polar night, when there is little or no direct sunlight, so UV exposure is typically very low. The picture is different in spring and summer, when long daylight hours and snow reflection can push UV higher.
Is UV reflected from snow in the Arctic?
Yes. Snow reflects a large share of UV radiation. In spring, when sunlight returns and snow still covers the ground, UV exposure can be higher than the air temperature suggests.
