Northern lights over Norway
Aurora forecast based on the Kp index — a measure of geomagnetic activity (scale 0–9). The higher the Kp, the further south the northern lights can be seen. Best chance with dark, clear skies and an open view to the north.

☀️ Light season. In May–July the nights are too light in Northern Norway (midnight sun) for the aurora to be seen — even at high Kp. The aurora season is normally September–March.

Tips for seeing the aurora
- Seek darkness — get away from city lights.
- Open view to the north.
- Clear sky: check the cloud forecast first.
- The best time is often 21:00–02:00.
- Let your eyes adjust to the dark for 15–20 min.
- A camera often sees faint aurora before the eye does.
What is the Kp index?
The Kp index measures disturbances in the Earth magnetic field on a scale of 0–9. At
Kp 3–4 the aurora can be seen in Northern Norway, at
Kp 5+ (geomagnetic storm) all the way down to Southern Norway. The values update every three hours.
