Northern lights Landmannalaugar tonight

7-day outlook for Landmannalaugar

Based on CME arrival predictions from NASA DONKI. Arrival times ±6 hours.

What Kp is needed here?

Landmannalaugar sits at a magnetic latitude of approximately 64°N. The Kp index - a global measure of geomagnetic activity on a scale from 0 (quiet) to 9 (extreme storm), updated every 3 hours - needs to reach Kp 3 before the auroral oval expands far enough south to be visible from here.

At Kp 3, visibility is possible from Landmannalaugar but skies need to be clear and dark. Cloud cover and light pollution remain the main obstacles even when Kp is high enough.

Light pollution is the biggest obstacle after cloud cover. These sites give you the best dark northern horizon within reach.

Best time to see the northern lights in Landmannalaugar

Landmannalaugar's aurora season runs from late September through to March, when nights are long enough for truly dark skies. The equinox months, September and March, bring a natural boost in geomagnetic activity, making them statistically the best of the season. Summer months bring too much twilight for aurora to be visible at this latitude.

Activity peaks around the September and March equinoxes, when Earth's magnetic field geometry is most favourable for coupling with the solar wind. Events during these two windows tend to produce the strongest displays of the year for observers at Landmannalaugar's latitude.

April through August brings persistent astronomical twilight that washes out aurora completely. Even strong events (Kp 6+) remain invisible during this period because the sky never gets dark enough.
