Northern lights are formed when electronically charged particles from the sun collide with atoms and particles within the earth's atmosphere. The northern lights season in Iceland is from September to mid-April each year, and all months are as good as the other to see the lights. It depends on the aurora activity and the weather conditions each day as they are very unpredictable, which is a part of their charm. Iceland is an ideal place to view the lights due to its location near the Arctic Circle and its scarce population, i.e., it is easy to find a place with no light pollution.
Ölfus municipality is one of the most popular viewing points for the Northern Lights in the south due to little to no light pollution and panoramic views.
