Sweden enjoys a generally temperate climate, thanks to the Gulf Stream. Above the Arctic Circle, winter can be crisp and invigorating. In the south, winter is generally mild with an average of temperature above 0C/32F degrees, but temperatures can vary markedly in different parts of the country.
Sweden's northerly position has a definite summer advantage in that temperatures are rarely extreme and humidity levels are not high.
To describe the weather in Sweden, the country can be divided into three regions; central and southern Sweden, the northeast, and the northwest or far north.
In central and southern Sweden the winters are short and quite cold, and summer temperatures are similar to those in southern England, but with a lot more hours of sunshine and daylight. In the northeast meanwhile the winters are severe, the more so as you travel further north, while the summers can be surprisingly warm. In the far north the winters are also severe, with snow lying the year-round on elevated areas, and the summers are short and changeable. And because Sweden lies at a high latitude much of the country has very long hours of daylight in summer and very long nights in winter.
So, no Polar bears were afraid, just the wonderful Swedish weather and all the fantastic things you can do in it.
