Stockholm Weather Overview:
Although you may not think it if you’re there in January, Stockholm has a relatively mild climate compared to other cities at or near the same latitude. It’s quite warm in summer when the temperature can touch 80f occasionally but February only manages an average of -3C.
All Time Highs and Lows:
The highest temperature ever recorded in Stockholm was 36C on 3rd July 1811 whilst the lowest ever temperature was recorded just three years later when, on the 20th January, the city suffered -25.1C.
Stockholm’s climate is described as hemiboreal humid continental by the Koppen climate classification system although it does have influences from the Baltic Sea although not as pronounced as it is away from the North Sea/Atlantic influence.
Spring: Spring can seem a long time coming as temperatures, even into April, often struggle to get above 10C. However, with the lengthening days, sunshine hours double over the course of the season and by the time May is over, summer has truly arrived and temperatures nudge the 70s.Rainfall is still low and the number of rainy days means you’re only likely to suffer rain on one day out of three.
Summer: Stockholm’s summers are idyllic with temperatures in the low to mid seventies and nearly nine hours of sunshine a day. Strangely, July has twice as much precipitation as January but most of this comes as heavy downpours accompanying thunderstorms as the temperature rises. Not infrequently you’ll find temperatures in the eighties and occasionally touching ninety so be prepared for some heat!
Autumn: It’s not long before the heat of summer is a distant memory. September temperatures drop away sharply but then so does the amount of rain. Sadly too the amount of daylight and sunshine dips dramatically and by the end of September you’re lucky to see an average of four hours a day of sun.
Winter: Temperatures in winter are almost always below zero but depending on how severe the winters are you’ll find either lots of snow or plenty of rain. Snowfall can be expected at any time from December through to March and you may even experience fog banks rolling in off the Baltic, especially on some of the more outlying of Stockholm’s islands.
Best Time of Year to Visit:
Early summer is the best time for a trip to Stockholm as the weather hasn’t yet got hot and sticky, the school holiday crowds haven’t appeared yet and you’re visiting close to the time of the summer solstice so there’s plenty of daylight in which to see the sights.
