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.

Vermont has warm and humid summers with average high temperatures of 75°F (23.9°C) to 82°F (27.8°C) in the peak of July. Summer nights are mild with average low temperatures of 55°F (12.8°C) to 60°F (15.6°C). Winters are extremely cold and snowy, and average low temperatures during January are in the cold 2°F (-16.7°C) to 12°F (-11.1°C) range across the different regions in the state. Winters are sometimes too cold to receive either snow or rain. Spring is a little muddy in April, while the autumn is colorful with mild temperatures. Although it rains throughout the year, spring and early summer tend to receive more rainfall. The annual precipitation averages 50" (1270mm), and the average snowfall easily registers between 80" (2032mm) to 100" (2540mm) during the winter. Humidity rises to 70% during the summer. Sunshine in January is short of 5 hours a day, while the average annual sunshine is 2295 hours.

Vermont experiences many thunderstorms during late spring and early summer. Snowstorms are frequent during the winter - the intensity of these storms varies, but many are strong enough to deposit large quantities of snow and often create deep snow packs. Vernon recorded Vermont's highest ever temperature of 105°F (40.6°C) on July 4, 1911, while Bloomfield recorded the coldest temperature of -50°F (-45.6°C) on December 30, 1933.

The worst time to visit Vermont

The worst time to visit Vermont is the winter season, from December to February, as the extreme cold weather descends from the Canadian North.
Vast amounts of snow accumulate in the mountains, and many highlands register more than 120" (3048mm). Vermont experiences icy conditions with many days when the sun is barely above the horizon.
The season is generally slow for tourists, but many ski-resorts are open during the winter and see enthusiastic visitors. Weather-wise, it is a time to avoid Vermont as the temperatures seldom rise above freezing and are not comfortable to anybody except to those people who are accustomed to it.

Weather hazards

Vermont is prone to thunderstorms in spring and early summer. They take the form of lightning and rain and can take severe form in the highlands and mountains.
Snowstorms and blizzards are frequent during the winter. These take violent turns in a few cases, last for a, while and create icy conditions, large snow deposits, and a severe drop in visibility. Many times visibility restricts to a few meters, and it is extremely difficult to maneuver through the snowy roads.
Vermont has few large cities, and the capital at Montpelier is the least populous of all state capitals in the United States - so the stall due to the storms is not as huge as in some of the other cities of America.
