Sapporo Weather

Sapporo has a humid continental climate , with a wide range of temperature between the summer and winter. Summers are generally warm and humid, but not oppressively hot, and winters are cold and very snowy, with an average snowfall of 5.96 m (19 ft 7 in) per year. Sapporo is one of few metropolises in the world with such heavy snowfall, enabling it to hold events and festivals with snow statues. The heavy snowfall is due to the Siberian High developing over the Eurasian land mass and the Aleutian Low developing over the northern Pacific Ocean, resulting in a flow of cold air southeastward across Tsushima Current and to western Hokkaido. The city’s annual average precipitation is around 1,100 mm (43.3 in), and the mean annual temperature is 8.5 °C (47.3 °F).
