Since a lot of houses in the town are painted blue, Sortland is sometimes referred to as "the blue city". The Midnight Sun occurs from May 23 to July 23. Great places to observe the Midnight Sun includes the Sortland Bridge, Ramnflauget, Godfjorden, Holm and Skytterhaugen in the Vestmarka residential area. Because of Sortland's high latitude, there is no real darkness between late April and mid-August. From November 30 to January 12 the sun remains below the horizon and is not visible. The return of the sun is an occasion for celebration. The Polar Night does not mean that it becomes totally dark. The experience of the winter with the uniqueness of the light, the northern lights and snow is fantastic. Especially beautiful is the blue light southwards where the sky can also be coloured in pink, just before it becomes dark.
