Oslo Weather

Despite its location in the northern latitudes, Oslo is blessed with a relatively temperate climate due to the current of warm air which moves across the Atlantic from the Gulf Stream. Even in summer, the temperatures remain cool and a brisk wind and sudden rain showers can happen at anytime. Rainfall is spread throughout the year, with August being the rainiest month. Winter brings plenty of snow, but the weather never gets too bitter.

Long summer days

Summer is simply wonderful in Oslo. The weather is mild and pleasant, with temperatures mainly in the low 20s and only rarely heating up to 30°C. The best part of the weather here, however, are the incredibly long sunny days, when you can wander around late into the evening under a magical pale twilight. Even during peak  summer, nights can be a bit chilly, so always bring a sweater when you head out after dark.

Long winter nights

At the other end of the spectrum is Oslo’s winter. The temperatures hover around freezing and snow is plentiful, making the city an incredible winter sports venue. This winter wonderland can be a bit dreary, however, due to the extremely short days. It seems perpetually dark from November to February, which can dampen many people’s spirits.

To make up for it, Oslo has the surreal and spectacular Northern Lights. There are very few tourists during the winter, and many attractions are closed during the cold winter months. But the locals don’t sit around and brood over the long dark winters; they get out and enjoy every minute of sunshine and keep the pubs warm and festive the rest of the time.
