Winter officially begins at the winter solstice (December 21 or 22) and ends at the spring equinox (March 21 or 22). However, the cold weather and snow can arrive sooner and stay much later. The amount of snow Vermont receives varies from winter to winter and from one region of the state to another. The lower elevations near Lake Champlain receive about 60 inches of snow each year. Up to 120 inches of snow may fall each year in the southern Green Mountains. The average temperature for the winter season is 22 degrees F. The cold weather is broken up by thaws when temperatures reach 40 or 50 degrees F. and the snow melts. Toward the end of March, the grip of winter begins to weaken.
