June 20th, 2021, is the summer solstice, the longest day of the year, and the official start of summer in the Northern Hemisphere. This means that the start of winter is only six months away, December 21st, 2020, and daylight today is 5h28m longer than then. Ski season is even closer as it usually starts in November.
Of course, in the Southern Hemisphere, the day is the shortest day of the year and the beginning of winter. Southern Hemisphere skiing and riding has already begun.
