When to go
From our 2026 climate study, not the live forecast.A Bohuslän spa-and-fishing town right on the Norwegian border — 19–22°C, the car-free Koster islands (Sweden's only marine national park) a short ferry out, and the cold-clear Skagerrak for the brave. Most Oslo visitors drive (under two hours); the nearest airport is Gothenburg. The quietest, most niche pick on the list — that is the point.
