The climate in Sweden varies from north to south. Despite its northerly placement, the country is generally temperate due to the warm offshore Gulf Stream currents. There are three different climatic zones in Sweden: the south has an oceanic climate, the centre has a humid continental climate, and the north has a subarctic climate.Summers in the south and centre of Sweden are warm and pleasant, with average high temperatures ranging between 68°F and 77°F (20°C and 25°C). In the winter, temperatures in these regions average between 25°F and 36°F (-4°C and 2°C).In the north it is substantially colder, with short, cool summers and long, snowy winters, while temperatures frequently drop below freezing between September and May. Rain is possible in Sweden at any time of year, but is most common in late summer. The southwest of the country receives the most rain.The best time to visit Sweden is in the summer months from June to August, when the days are long and warm and the open-air museums and restaurants are open. As summer is the most busy and expensive time to visit Sweden, some travellers prefer to go in the spring or autumn, which are both very pleasant seasons and far less crowded.
