The climate of Vermont

Vermont has a humid continental type of climate (Köppen climate classification Dfb) with warm and muggy summers and cold and snowy winters. New Hampshire in the east, Massachusetts in the south, New York in the west and the Canadian province of Quebec in the north, border the state. Vermont is cold, barring the summer months like the rest of the New England region in the northeastern part of the United States. The Green Mountains extend in the north-south direction and stretch up to the middle of the state - Lake Champlain lies in the west, while the Connecticut River Valley occupies the east of the mountains.

Vermont, the Maple state, has temperate broadleaf and mixed forests with a large cover of maple trees. New England-Acadian forests that consist of northern hardwood and conifers form a majority of the forests, while the northeastern coastal coasts that are of mixed oak adorn the southwest part of the state. Lowland forests of the Eastern Great Lakes constitute the western frontiers of Vermont. The mountains are alpine and have high peaks, and much of the terrain is a combination of mountains, highlands, rivers, and river valleys.
