Sweden's weather has many faces. The country enjoys a mostly temperate climate despite its northern latitude, mainly because of the Gulf Stream. Stockholm is warmer and milder, while in the mountains of northern Sweden, a sub-Arctic climate predominates.
North of the Arctic Circle, the sun never sets for part of each summer during June and July, which is called the Midnight Sun, one of Scandinavia's natural phenomena. The opposite occurs in the winter when the night is unending for a corresponding period. These are the Polar Nights (another one of Scandinavia's natural phenomena).
There is an important weather divergence between northern and southern Sweden: The north has a long winter of more than seven months. The south, on the other hand, has winter weather for only two months and a summer of more than four.
Annual rainfall averages 24 inches and the maximum rainfall occurs in late summer. Sweden boasts considerable snowfall, and in Sweden's north snow remains on the ground for six months each year.

No matter where you go, you'll experience long, mostly sunny days that are perfect for being outside.
What to pack: Nights are quite cold, especially in the northern part of the country and along the coast, so you'll still want to pack warm layers. Otherwise, during the day in Stockholm and other major cities, you'll likely be comfortable in jeans and a long-sleeved shirt or sweatshirt.
