Best time to visit Stockholm: month-by-month weather (2026)

The best months to visit are June, July, August, and September, when daytime highs reach into the high teens and low twenties Celsius, including 21.0C in June, 21.9C in July, 20.4C in August, and 18.3C in September, alongside sunshine totals of 14.5, 13.4, 10.8, and 8.7 hours a day respectively. These months combine the warmest weather with the longest daylight hours of the year.

The trade-off is that July, the sunniest and warmest peak month, is also the wettest of the summer stretch with 110mm of rain, compared with 59mm in June and 75mm in August. Travelers who prefer fewer crowds and somewhat drier conditions might look at the shoulder months just before or after the June-through-September peak, while accepting cooler temperatures and less daylight.
