Conditions for northern lights in Luleå

It has to be sufficient solar energy to create aurorae in the atmosphere combined with the  energy impacting the atmosphere at an angle that is suitable for our location. Clear skies or scattered clouds are required for the northern lights to be visible. You can see them dancing over the city of Luleå, but they will be shy and not as prominent. Therefore we recommend you choose an open and suitably dark place and avoid well-lit places to any extent possible. 

There is no ‘timetable’. Northern lights may occur at any point during the hours of darkness and vary in duration. Northern lights are visible in Luleå from late August until the first days of April. During the rest of the year, the skies are too bright for the phenomenon to be visible.
