Oslo Weather in August
Norway · late summer in Northern Hemisphere
Oslo sits at the head of the Oslofjord, a 62-mile-long fjord that acts as a natural wind and temperature corridor into the heart of the city. The surrounding Nordmarka forest to the north and Ekebergåsen hills to the southeast create topographic sheltering that keeps Oslo significantly warmer than Norway's coastal cities. Oslo has Scandinavia's warmest summers (average 72°F in July) but winters are cold and snowy (average 28°F in January). The fjord moderates temperatures in coastal districts while inland forest districts see greater extremes.
Hot in many cities. Beach and outdoor destinations are at their peak.
