The Sweden weather you experience depends on where you are. It is actually possible to have snow in summer, but also sunbathe at midnight - all in the same country. The southernmost tip of the country is around 55 degrees latitude north and the northernmost tip around 69 degrees north, inside the Arctic Circle.
The Sweden weather in winter ranges from around -40 degrees Celsius to 2 degrees Celsius. In summer it tends to be from around 15 degrees Celsius to 32 degrees Celsius - sometimes even hotter.
January through to March is when snow can be expected, though in the far north this is more variable and less contained. It can rain at any time, and rather unfairly, it is the warmest months of July and August that gets the most rain.
The Sweden weather is mostly temperate. This is mainly because of the Gulf Stream waters that lap its shores and bring temperate winds from the west. Southern Sweden can be surprisingly warm and a lot less cold than many would expect for its northern position. In the mountains of the north, however, a bitterly cold sub-Arctic climate prevails most of the time.
Some 15 percent of the country is within the Arctic Circle. This means that from around the end of May until the middle of July that part has no night. This is the Midnight Sun. Any traveler who is not used with this amount of continuous daylight will most likely have difficulty in sleeping in the north of Sweden during the summer months.
The converse is true for the northern 15 percent; in winter they have perpetual darkness from the middle of December until the end of the first week of January. During this time, Stockholm, the capital to the south, has only five and a half hours of daylight.
The Sweden weather is enhanced by two major factors. One we have touched on already; the effects of the Gulf Stream, which brings pre-warmed winds over the land providing a temperate climate. The other factor is the continental high pressures that develop to the east. These create Sweden weather that is sunny, often quite hot in summer, and while cold in winter, they do relieve a dark days considerably.
In winter in the far north, the average Sweden weather temperatures can plunge to -40 degrees Celsius. In summer in the southern parts it can exceed 32 degrees Celsius on occasion. This is a vast temperature range that few countries can equal, and it aptly demonstrates the great diversity of weather to be found within Sweden.
The Sweden weather has a lot of precipitation throughout the year. The rainiest season is during late summer, especially in the southeast where they get around 24 inches of rainfall a year. By contrast, in Lappland in the north the annual rainfall is only half that amount.
