How accurate is the Iceland aurora forecast?
The forecast hasn't been tested against aurora cameras here, because no public labelled camera data exists for this region. It runs at medium confidence, and we make no accuracy claim for it.
Tips for seeing the aurora in Iceland
- Darkness is the first limit: about 8 dark hours in mid-September, 15 in mid-December and 9 in mid-March.
- Clouds are the second. October had the fewest nights free of low cloud at the airport (41%), 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.
