I experienced the winter in Sapporo for four days during December 2015
Sapporo, despite actually lying just south of Nice, France, can be a a city of cold and snowy winters. With the Siberian High front developing over Eastern Russia and the Aleutian Low front developing north in the Pacific Ocean, a cold flow of air comes from the north and down to West Hokkaido. The result is usually cold and snowy winters, almost six meters of snow on average. In Niseko, a few hours by car from Sapporo this results in a ski resort with some of the best powder snow in the world. In Sapporo this means freezing winters, much trepidation, but also warm periods melting the snow to water which becomes ice due to the Heave, the cold ground. A problem also known in Norway.
