The Northern Lights – or Aurora Borealis as the phenomenon is also known – actually occur all year round, but cannot be seen during the summer months in Greenland due to the light night skies and the Midnight Sun. The effect is often seen around midnight and is best experienced on a dark, clear night sky from September until April.

If you are travelling during this period, you can see the Northern Lights anywhere in the country, but in South Greenland the phenomenon can be seen from as early as the end of August.
A well-known Greenlandic saga recounts that the when the Northern Lights are dancing across the sky, it means that the spirits are playing football with a walrus skull.
