Thanks to the Gulf Stream Sweden has a higher temperature than would be expected from a country in its geographical position. The climate is temperate with large differences between summer and winter temperatures and a considerable difference between the North and South of the country with the North obviously tending to be colder (especially in winter).
Summer temperatures in the southern cities of Sweden average out around 18°C and winter temperatures around -2°C. The east coast tends to be colder with many parts of the Baltic Sea freezing over in the winter months.
Due to Sweden’s high geographical latitude the country experiences near complete 24 hours of day time in the summer and near 24 hours of night in the winter.
