In general, May to September is the best time to visit Sweden – north or south. Summer weather in Sweden is similar to that in southern Britain, though there are more hours of sunshine and less rain. By the end of August, the leaves in northern Sweden start to change colour and night frosts are not uncommon; the first snows fall in September. In Stockholm, snow can fall in October but doesn’t generally settle; by November, though, the ground is usually covered in a blanket of snow, which will last until the following March or even April, when there can still be snow showers. Winters in the south of Sweden are often mild whilst in the north you’re likely to encounter snow until well into May and temperatures can fall to -30C.
