Depending on where the traveller goes concerning latitude and time of the year, the experience of contrasting phenomena of the Northern Lights or Midnight Sun can be seen. Between September and March, the short daylight hours are an ideal time to view the northern lights or aurora borealis-amazing displays of light within contrast.
In summer, the sun does not completely dip below the horizon- a polar phenomenon is known as the midnight sun. Depending on where you go, the Midnight Sun can be possible to see for a single day to more months. In Ilulissat, for example, the midnight sun appears from mid-May to late July.
