Winter is one of the four seasons: Spring, Summer, Autumn/Fall, and Winter. In the Northern Hemisphere, Winter is the coldest season. It spans from December to March each year. Most of our Magic SandBox friends live in the Northern Hemisphere in the United States and Canada. In the Southern Hemisphere, Winter is June, July, and August. That is when it is very cold there. The Southern Hemisphere is below the equator. This includes parts of Africa, Australia, South America, and Antarctica.
