February offers near-peak conditions for aurora across the northern hemisphere's high and mid-latitude zones. Nights remain long - averaging 14 to 16 hours at 60°N - and skies tend to be clearer than in the deep winter months at some Scandinavian inland locations where persistent cloud is less common. The Kp index (a global measure of geomagnetic activity, 0 to 9) needs to reach Kp 1-2 for Arctic sites and Kp 3-4 for mid-latitude locations across Scotland, Norway's southern coast, and Canada's populated south.
February excludes the lowest-latitude northern sites - those that need a major geomagnetic storm at Kp 5 or above to see aurora. At these southern fringes of the auroral zone, nights are shortening as winter gives way to spring, and the geometry of the auroral oval becomes less favourable. Locations like London, the Netherlands, and central Germany have a narrower window in February than they do in December or January.
In the southern hemisphere, February marks the very start of the aurora australis season at the highest-latitude sites. Darkness is beginning to return to locations like Ushuaia in Patagonia and Stewart Island in New Zealand's far south. Conditions are marginal rather than reliable this early in the season - any clear, dark night with elevated Kp is worth watching, but consecutive good nights are rare until March.
Planning your trip in February
Cold but often more settled than January in the Scandinavian interior. Inland Lapland and Abisko in Sweden frequently benefit from stable high-pressure systems in February, bringing clear skies for several nights at a stretch. Coastal Norway and Iceland remain variable. Temperatures range from -10°C to -20°C in Finnish and Swedish Lapland.
Still long nights. Tromsø has around 14 hours of darkness. Iceland gets 8 to 9 hours of daylight, leaving 15 or more hours of night. Scotland and the Baltic states have around 10 hours of darkness. The second half of February brings incrementally shorter nights, but all high-latitude sites remain well within their prime season.
February is still peak season but slightly less crowded than January after the post-Christmas rush. Some destinations see a dip in the first two weeks before Valentine's Day demand pushes prices back up. Book ahead, particularly for Abisko where capacity is limited.
