Weather in Oslo

Best time to visit

Oslo has a humid continental climate with sufficient precipitation to keep its surrounding hills green and lush. Its coastal position also helps to moderate its climate, especially given its northerly latitude.

Spring (March to May) sees the mercury climb rapidly. With temperatures averaging 2°C (35°F) in March and the days getting sunnier, March is often a good time to ski and the country plays host to the Norwegian Alpine Championship. By May, the averaging temperatures get to 12°C (57°F).

Summer (June to August) is lovely in Oslo. July is the warmest month with plenty of sunshine and temperatures range from 13°C (55°F) to 22°C (72°F). During the long summer days, when the sun drops only briefly below the horizon and it never gets truly dark, people in Oslo spend much of their time outdoors. This is the best season to join the locals exploring the parks and hiking paths, or simply relaxing on the beaches of the fjord.

Autumn (September to November) sees the temperatures drop quickly and the days shorten. By November, the average low is -1°C (30°F) while the average high is 4°C (39°F). Snow starts to fall to the delight of snow sports enthusiasts.

Winter (December to February) is dark with very few hours of daylight, and temperatures often fall well below freezing point. But the cold season does have its compensations, including plentiful opportunities to enjoy cross-country and downhill skiing. January is the coldest month, -7°C (19°F) is the average low while 1°C (34°F) the average high.
