The best time to go to Sørstraumen depends on whether you're seeking the Midnight Sun or the Northern Lights.
For those keen to experience the Midnight Sun, the period from late May to late July offers continuous daylight. During this time, the sun remains visible above the horizon 24 hours a day, providing ample opportunity for activities like fishing, hiking, and exploring the stunning fjords at any hour. This is ideal for travellers who want to maximise their daylight hours for outdoor pursuits.
If catching the Northern Lights is your primary goal, the best time to visit is between September and March. The long, dark nights of the Arctic winter provide a great backdrop for this natural phenomenon. While temperatures are colder, this period also offers opportunities for winter activities like dog sledding and snowmobiling.
