Weather and climate

Contrary to popular belief, Norway is not “in the freezer” throughout the year. The Golf stream, a warm sea current originating from the Caribbean Sea and ending up to Barents Sea, is primarily responsible for Norway’s rather mild climate, at least compared to other countries of the same latitude.

Summers in Norway can be pleasantly warm, with the average high temperature in Oslo exceeding 20 degrees Celsius. Oslo’s record high is 35 degrees, though temperatures above 30 are far from a frequent phenomenon.

Oslo has a stable climate, compared to the coast of Norway, with more sunny days. It’s common to enjoy the beaches along the fjord, go sailing or do sports outside in the spring and summer season.

The fall can be similar to the North East of the US with cooling temperatures and colorful leaves. The Norwegians love their mountains, and the fall is a popular time to take mountain walks while picking an abundance of berries and mushrooms that are free for all.


This is not to say that it cannot get cold in Norway. Winters in Oslo and adjacent areas are marked by average temperatures between -10 and 0 degrees, with temperatures around -15 degrees being the norm for a few days every year. Snowfalls can occur between October and April, but they are most frequent in January, February and March. In the recent years the climate changes have been very visible in the Oslo region with more rain and less snow. Those who love to ski are therefore going off to the mountains to look for good snow conditions whenever they can.

“There is no such thing as bad weather, only bad clothes”, according to a popular Norwegian saying.  Winter clothes are best purchased in Norway or in countries with similar cold climate zones and wool is recommended during the days of winter.
