Northern lights in Kiruna in March
One of the best months of the year — 46% of March nights offer a real window.
The numbers behind it: March nights in Kiruna average about 9 dark hours, geomagnetic activity reaches local viewing levels on 85% of days, and 55% of nights offer at least one reasonably clear hour after dark.
Neither clouds nor solar activity dominates — March failures are usually bad single-night luck. Several nights in a row is the honest insurance policy.
March also benefits from the equinox effect: around the equinoxes the Earth's magnetic field couples more efficiently with the solar wind (the Russell-McPherron effect), and 30 years of records show measurably more active days than in midwinter.
Numbers come from 1996–2025 Kp records (GFZ Potsdam) and 2015–2024 hourly cloud history for Kiruna itself — the full method is on the methodology page. Travelling soon? Check tonight's live Kiruna forecast.
