What's the Midnight Sun?:
The midnight sun is a natural phenomenon found in latitudes north of the Arctic Circle (as well as south of the Antarctic Circle), where the sun is visible at the local midnight. With adequate weather conditions, the sun is visible for full 24 hours a day. This is great for travelers planning long days outdoors, as there will be sufficient light for outdoor activities around the clock!
The Midnight Sun's Best Location:
The most popular Scandinavian location for travelers to experience the natural phenomenon of the Midnight Sun is in Norway at the North Cape (Nordkapp). Known as the northermost point in Europe, at the North Cape there are 76 days (from May 14 - July 30) of proper midnight sun and an additional few days with partial sun before and after.

If You Can't Sleep...:
In Norway and Greenland, locals often adjust to these changes naturally and require less sleep. If you have problems sleeping due to the daylight during Midnight Sun, try to darken the room by covering the window. If this does not help, ask for assistance - you won't be the first. Scandinavians will understand and will do their best to help eliminate light from your room.
A Scientific Explanation of the Midnight Sun:
The Earth orbits the Sun on a plane called the ecliptic. The Earth's Equator is inclined with the ecliptic by 23°26'. As a result, the North and South poles are in turn inclined toward the Sun for 6 months. Close to the summer solstice, on June 21, the Northern Hemisphere reaches its maximum inclination toward the Sun and the Sun illuminates all the polar area down to latitude +66°34'. As seen from the polar area, the Sun does not set, but only reaches its lowest altitude at midnight. Latitude +66°34' defines the Arctic Circle (southernmost latitude in the Northern Hemisphere where the midnight sun can be seen).
