When is the best time of year to see the northern lights?

The aurora borealis are potentially visible under dark skies from late August to mid-April preferably under a clear, cloudless sky. While they occur year round they are weaker than sunlight and therefore sightings aren’t possible from May to July and for most of August. Spring and autumn generally provide more stable weather conditions and milder temperatures plus there is greater aurora activity around the equinoxes. November through to February offer the darkest skies and longer evenings for maximum sky-gazing. The strongest lights tend to appear between 9pm and 2am, though the best sightings often occur between 11pm and midnight. Between 4am and 5pm there is generally too much daylight to see the aurora – exceptions are the darkest months of the year and higher latitudes such Svalbard, where it is dark 24/7 from mid-Nov to end of Jan.
