The country is much further away from the equator than Central Europe. This means that the winter days in Norway are much darker, colder and also shorter. The country is under cold polar climate. Depending on the season, the average daytime temperatures range between -1 and 19 degrees. In some parts of the country the temperature raises up to 23 °C. In the colder months and depending in the region, the temperature lowers down to -6°C in a month's average.
