The rules are different above the Arctic Circle

Tromsø is at 69.6°N — 400 kilometers above the Arctic Circle. The sun does not set from late May to mid-July (midnight sun), and it does not rise from late November to mid-January (polar night). Between those extremes, the light is extraordinary: golden hour can last most of the waking day in autumn and spring, and the polar twilight in January — a soft blue-purple glow lasting only a few hours around noon — produces conditions impossible at lower latitudes. Northern lights are regularly visible from September through March when skies are clear. The Storsteinen cable car (421 meters, Fjellheisen) gives a panoramic view over the city and the Tromsø archipelago. The Arctic Cathedral (Ishavskatedralen) faces northwest over the sound toward the island of Tromsøya.
