Tips for seeing the aurora in Tromsø
- Darkness is the first limit: about 6 dark hours in mid-September, 16 in mid-December and 8 in mid-March.
- Clouds are the second. September had the fewest nights free of low cloud at the airport (45%), so plan a few nights, not one.
- A bright moon washes out faint aurora; strong displays still show. Use the calendar above to find the moon-free stretches.
- Get away from street lights and give your eyes 15 minutes to adjust. A phone camera often shows more colour than the eye.
