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.

Summer sees a significant influx of tourists, especially in the Green Mountains and state parks.
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.
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.
Weather in January
January is the snowiest and coldest month of the year in Vermont. The New Year alternates between a few hours of daily sunshine, gloomy skies, and inclement weather. Temperatures drop even below -10°F (-23.3°C) in many places, while the average temperatures are between 2°F (-16.7°C) to 31°F (-0.6°C).

Snowstorms are frequent in January, and the roads and highways need regular snow removal measures such as cleaning and salting. Blizzards may cause even interstate highways to close down in many places! It is an excellent idea to change to snow tires on vehicles during the winter, and mountain roads may even need tire chains for safe driving on the slippery ice. Overall, out-of-state tourists with families avoid a visit to Vermont in January.
Weather in February
February is cold and icy in Vermont as the state experiences an average of 15" (381mm) to 18" (457.2mm) of snowfall. Bitterly cold nights see average temperatures in the 5°F (-15°C) to 15°F (-9.4°C), while the days have mostly freezing temperatures. The presence of wind makes the conditions feel chillier than the actual temperatures. Sunshine is not at its strongest, and the February sun finds it hard to break the cloud cover. Rain averages 2" (50.8mm) to 3" (76.2mm) and resembles more of ice than water drops. Rutland, along state highway 4 in Southern Vermont has average temperatures in the 9°F (-12.8°C) to 32°F (0°C), while Burlington in Northern Vermont averages between 13°F (-10.6°C) to 31°F (-0.6°C).
