Vermont’s weather changes a lot from month to month. These shifts create four distinct seasons, each with its own vibe for residents and visitors.
Winters get cold and snowy, with temperatures often dipping below freezing. Summers, on the other hand, feel warm and comfortable—ideal for anyone who loves being outdoors.
Vermont’s monthly weather swings from frigid January averages around 14-29°F to warm July highs of 76-81°F. Significant snowfall hits between December and March, and the heaviest rainfall usually shows up in late spring and summer. If you know these monthly patterns, you can plan your trip better or just be ready for whatever the season throws at you.
Weather in the Green Mountain State doesn’t just change by month—it shifts by region too. Northern towns like Newport stay colder than southern spots like Bennington.
Every month brings something different. You might ski and snowshoe in winter or hike and leaf-peep in fall. Vermont really does have something for weather-conscious travelers all year.
Overview of Vermont’s Monthly Weather
Vermont gets four real-deal seasons, with wild temperature swings—from winter lows near 10°F to summer highs in the 80s. Precipitation stays pretty steady, but mountainous areas get hammered with snow in the winter.
Temperature Trends by Month
Vermont’s temperatures stick to a classic continental pattern. Winter months (December through February) get the coldest, with averages from 10°F up to 30°F.
January hits hardest, bringing the coldest stretch. Snow usually covers everything, making it peak season for winter sports.
Spring creeps in from March through May. Temperatures start in the 40s in March and climb to the 60s and 70s by late May.
Summer—June, July, and August—brings the warmest days. Highs usually hit the upper 70s to low 80s, while nights dip to the 50s and 60s.
Fall cools things down from September through November. Early fall stays pleasant, with highs in the 60s and 70s. By November, temperatures drop back into the 40s as winter edges closer.
Precipitation Patterns Throughout the Year
Vermont sees about 36-40 inches of precipitation each year. Rain and snow show up throughout the seasons.
Winter brings mainly snow, especially in the Green Mountains. These areas get the most accumulation, giving Vermont its iconic winter look.
Spring and summer bring regular rainfall. Thunderstorms pop up often in warmer months, keeping everything green.
Fall is a mixed bag—some rain and the first flurries of snow. Late fall usually brings those first snowflakes as temperatures slide below freezing.
Most months get 2-4 inches of moisture, whether it’s rain or snow.
Daylight Hours and Sun Exposure
Vermont’s northern location means daylight hours swing a lot by season. Winter days feel short—December only gets about 9 hours of daylight.
The sun hangs low in winter. Snow cover bounces light around, so some days seem bright even when daylight is limited.
Summer flips the script with the longest days. June can have nearly 15 hours of daylight. The sun sits high, giving you max solar energy.
Spring and fall sit in the middle. Daylight hours gradually rise or fall, and both September and March offer roughly 12 hours of light.
Clouds are pretty common, so Vermont often gets partly cloudy or overcast skies.
Monthly Breakdown: Weather in Each Month
Vermont cycles through four seasons, and each one brings its own temperature and precipitation changes. The state’s New England location means cold, snowy winters and warm, humid summers, while spring and fall feel milder but unpredictable.
Winter Months: December to February
Vermont’s winters can get rough, with heavy snow and freezing temperatures. December usually sees highs around 30°F and lows near 15°F. Snow starts falling regularly, and December alone can get 15-20 inches.
January is the coldest month. Highs drop to the mid-20s°F, and nighttime lows often sink below 10°F. Northern Vermont sometimes plunges well below zero. Snowfall peaks in January—20-25 inches is pretty normal.
February stays cold but begins to warm up a bit by the end. Highs average in the upper 20s°F to low 30s°F. The Green Mountains often get over 30 inches of snow in February.
Winter storms can dump 6-12 inches at once. Sometimes, warm air glides over cold ground and causes ice storms. These can make driving dangerous and knock out power.
Spring Months: March to May
Spring warms things up slowly, but weather stays unpredictable. March hangs onto the cold, with highs in the upper 30s°F to low 40s°F. Snow still falls, but rain starts to take over as it gets warmer. Maple syrup season kicks off when days get above freezing but nights stay cold.
April warms up more, with highs in the mid-50s°F. Most of the snow turns to rain, though late snowstorms can still surprise you. Melting snow makes dirt roads muddy.
May finally brings nicer weather. Highs hit the upper 60s°F to low 70s°F, and lows hover in the 40s°F to low 50s°F. Rain picks up, and thunderstorms start rolling through. Trees leaf out and wildflowers pop up everywhere.
The Green Mountains run cooler and wetter than the valleys. Spring usually arrives 1-2 weeks later up high compared to lower spots.
Summer Months: June to August
Summer in Vermont means warm, humid days and plenty of thunderstorms. June feels comfortable, with highs in the mid-70s°F to near 80°F. Humidity makes it feel even warmer, and late afternoon storms are common.
July gets the hottest, with highs in the upper 70s°F to low 80s°F. Some days spike into the upper 80s°F or low 90s°F. Nights stay in the 50s°F to low 60s°F. Rain totals about 3-4 inches a month.
August keeps the heat going but starts to cool off by the end. Thunderstorms still happen a lot, and heavy rain can lead to some local flooding. Some summers get dry enough for mild droughts.
The Green Mountains give you a break from the heat, with temps 5-10 degrees cooler than the valleys. Mornings can be foggy, and storms hit the peaks more often.
Autumn Months: September to November
Fall is famous for Vermont’s foliage, and the weather gets crisp. September stays warm, with highs in the low 70s°F, but nights drop into the 40s°F. That swing helps bring out the fall colors. Rain falls less than in summer.
October is peak foliage time. Highs drop to the upper 50s°F to low 60s°F. Morning frost shows up by late October. Some days are sunny and clear, while others turn cloudy or rainy.
November signals winter’s return. Highs fall to the mid-40s°F, and the first snow usually shows up—though it doesn’t always stick. Leaves are gone, and people start prepping for winter.
The Green Mountains get frost and snow earlier than the valleys. Fall colors peak first at higher elevations before moving down.
Regional Weather Variations in Vermont
Weather in Vermont jumps around depending on where you are. Mountains, valleys, and big lakes all play a part. The Green Mountains bring cooler temps and more snow, but Lake Champlain keeps nearby spots warmer in winter and cooler in summer.
Green Mountains Climate
The Green Mountains see Vermont’s wildest weather. These peaks make their own patterns, which can be totally different from the valleys.
Temperatures can drop 20-30 degrees lower in the mountains during winter. In summer, highs rarely get above 70°F up high.
Snow piles up in the Green Mountains. Some spots get 150-200 inches each winter, and snow sticks around from November through April.
Precipitation increases with elevation. Mountains catch more rain and snow than lowlands. Storms usually hit the western slopes first, dumping heavier precipitation there.
Winds pick up at higher elevations. Peaks can see gusts over 40 mph during storms, which makes for some brutal wind chills in winter.
Lake Champlain Valley Weather
Lake Champlain shapes a unique climate in western Vermont. The big lake keeps temperatures more moderate all year.
Winter stays warmer near the lake. The water rarely freezes solid, so air temperatures run 5-10 degrees higher than spots just a few miles inland.
Summer feels cooler along the shoreline. Breezes off the lake help take the edge off hot days. The water keeps heat waves from getting too out of hand.
Growing seasons stretch longer in the Champlain Valley. Spring shows up earlier, and fall frost comes later near the lake, which helps local farms.
Precipitation is different here too. The valley gets less snow but more freezing rain during winter storms. Spring and summer bring lots of thunderstorms that start over the warm lake water.
Green Mountain National Forest Conditions
The Green Mountain National Forest covers a mix of elevations and microclimates. Weather changes a lot across this protected area.
Elevation shapes climate zones within the forest. Valley floors get regular Vermont weather, but peaks can feel almost alpine. For every 1,000 feet you climb, temperatures drop about 3 degrees.
Dense trees keep things cooler in summer and block the wind. Snow builds up differently under the canopy than in open spots.
Seasonal swings are big here. Winter brings heavy snow loads that can snap branches and block trails. In spring, melting snow can flood lower areas.
Weather stations scattered through the forest track conditions at different heights. This info helps predict avalanche risk and trail safety. Mountain weather can change fast, so visitors need to stay alert.
Seasonal Highlights and Outdoor Activities
Vermont’s four seasons open up all kinds of outdoor fun. Each season brings its own weather, making some activities just right—like winter skiing in the mountains or summer adventures on the lake.
Winter Sports and Skiing Destinations
When snow covers the Green Mountains from December through March, Vermont turns into a winter sports hotspot. The state gets steady snowfall, and February often takes the prize for most snow.
Killington Resort is a top pick for skiing. It usually opens in mid-November—earlier than most—and sometimes stays open into late spring. Killington gets reliable snow and has plenty of snowmaking.
Jay Peak stands out for natural snow, averaging over 350 inches a year up in the Northeast Kingdom.
Other winter activities are just as popular:
- Cross-country skiing on groomed trails
- Snowshoeing through forest paths
- Ice fishing on frozen lakes
- Winter hiking (if you’re geared up for it)
Winter temperatures run from 10°F to 33°F. If you’re visiting, you’ll want to pack warm layers and waterproof gear.
Spring Outdoor Adventures
Spring runs from March through May and brings some unique outdoor options. March signals the start of maple sugaring, with nights below freezing and warmer days.
Mud season hits in early spring, turning trails and dirt roads messy as snow melts. Many hiking trails close for a while.
By May, things dry out and outdoor activities pick up:
- Waterfall viewing—Spring snowmelt fills up waterfalls
- Fishing—Lakes and streams get stocked with trout in April
- Early hiking—Trails become accessible again
- Wildlife watching—Migrating birds return and baby animals show up
Spring temperatures go from 35°F to 67°F by May. Weather changes fast, so bring layers.
Summer Recreation in Vermont
Summer brings Vermont’s warmest weather from June to August. Highs reach the upper 70s to low 80s, which is about perfect for all kinds of outdoor fun.
Lake activities are a summer staple. Lake Champlain and smaller lakes offer swimming, kayaking, and boating. By July, the water’s warm enough for a swim.
Mountain activities include:
- Hiking in the Green Mountains
- Mountain biking on forest trails
- Rock climbing and bouldering
- Scenic chairlift rides at ski resorts
Summer also means farmers markets, outdoor concerts, and plenty of festivals. Long daylight hours let you keep going well into the evening.
Black flies can get annoying in June, so you’ll want to pack some bug spray for your adventures.
Autumn Foliage and Fall Colors
When fall rolls in, Vermont’s most famous attraction jumps front and center: those jaw-dropping fall colors that sweep across the landscape from late September to mid-October. The Green Mountains burst into a wild mix of red, orange, and yellow.
Peak foliage timing really depends on where you are and how high up you get:
| Region | Peak Timing |
|---|---|
| Northern mountains | Late September |
| Central Vermont | Early October |
| Southern valleys | Mid-October |
People love to get outside and soak up the scenery when the temperatures hover in the 50s to 70s°F. The list of fall activities is pretty irresistible:
- Scenic drives along winding mountain roads
- Snapping photos of all that color
- Apple picking at local orchards
- Hikes with sweeping autumn views
- Covered bridge tours through the backroads
October gets crazy busy with leaf-peepers flocking in. Hotels fill up fast, and prices jump during those peak weeks.
The season gives you the best weather for being outdoors before winter sets in. Cool nights and warm days mean you can spend more time outside without freezing or overheating.
Monthly Travel Tips and Packing Advice
Vermont’s wild seasonal swings mean you have to change up your wardrobe throughout the year. If you want to stay comfortable—whether you’re dealing with winter’s bite, spring’s surprises, or summer’s heat—packing smart is a must.
Winter Clothing Essentials
Vermont winters are no joke, and you’ll need proper cold-weather gear from December to March. Temperatures often dip below 15°F, and snow piles up fast.
Start with base layers. Go for thermal underwear made from merino wool or synthetics—they wick moisture away from your skin. Skip cotton, since it’s useless when wet.
Add insulation layers to trap heat. Fleece jackets or down vests are solid choices. Down is especially good for Vermont’s dry cold, since it’s so warm and light.
Top it off with outer shells that block wind and snow. Choose waterproof, breathable jackets with sealed seams and vents. You’ll want to keep out the wet and let sweat escape.
Extremities need extra care in these temperatures. Wear insulated, waterproof boots rated to -20°F to handle deep snow. Wool socks help prevent blisters and keep your feet warm, even if they get a little damp.
Don’t forget these essential accessories:
- Insulated gloves or mittens
- A warm hat that covers your ears
- Neck gaiter or scarf
- Hand and foot warmers if you plan to be outside for a while
Spring and Fall Layering Recommendations
Spring and fall in Vermont are unpredictable. In May, temperatures can swing from 32°F to 68°F. September and October can range from 71°F down to 36°F.
Layering systems are your best friend. Start with a base layer that wicks moisture—synthetic or merino wool is the way to go.
Add mid-layers for warmth. Lightweight fleece jackets, wool sweaters, or synthetic puffers all work. Make sure they zip or button so you can cool off if you need to.
You’ll need outer layers for all the rain Vermont throws at you. Packable rain jackets fit in your bag, and water-resistant soft shells are great for staying active outside.
Footwear should handle mud and water. Waterproof hiking boots give you traction and ankle support. Gaiters help keep out debris if you’re hitting the trails.
Here’s some smart packing advice:
- Rain gear like a lightweight poncho or umbrella
- Extra socks—wool or synthetic, since they dry fast
- Versatile pants—quick-dry hiking pants work in most situations
Summer Gear and Sun Protection
Summers in Vermont usually sit between 57°F and 82°F. July is the hottest, with humidity and the occasional thunderstorm thrown in.
Wear lightweight clothing to stay cool. Shirts made from synthetic fabrics or merino wool wick away sweat. Light colors reflect heat better—so ditch the black T-shirts.
Sun protection is a must at Vermont’s higher elevations. UV rays get stronger up there, so sunburn sneaks up fast. Wide-brimmed hats keep your face and neck from frying.
Don’t leave these sun essentials behind:
- SPF 30+ sunscreen—reapply every couple of hours
- Sunglasses with UV protection
- Long-sleeve shirts—pick lightweight ones for extra sun coverage
Rain can pop up out of nowhere in summer. Pack a light rain jacket or poncho for those sudden downpours. Quick-dry shorts and pants save you from soggy misery.
Footwear options depend on what you’re up to. Breathable hiking shoes are solid for trails, sandals are perfect for town, and water shoes come in handy at the lake.
Best Times to Visit Vermont Based on Weather
Vermont’s seasons each have their own highlights. Fall delivers peak foliage from late September to mid-October. Winter is prime for skiing from December through March. Summer brings great hiking and lake days from June to August.
When to See Fall Colors
Vermont’s fall foliage usually shows off from late September to mid-October, but the timing shifts depending on elevation and location. If you’re up in the northern mountains near Stowe, expect peak colors from late September into early October.
Southern Vermont and the Lake Champlain Valley hit their stride in the first half of October. The Connecticut River Valley isn’t far behind.
Peak Foliage Timeline:
- Late September: Northern mountains and higher elevations
- Early October: Central Vermont and mid-elevations
- Mid-October: Southern valleys and lower elevations
Weather really shapes the season. Cool nights below 45°F and sunny days in the 60s make the colors pop. Warm falls push the peak later, but an early frost can cut the show short.
If you want the best chance, plan your visit between September 25 and October 15. Keep an eye on local foliage reports, since the peak can shift by almost a week depending on the weather.
Ideal Months for Skiing and Snowboarding
Vermont’s ski season usually runs from mid-December to late March. February stands out for the most reliable snow and deepest powder.
Killington Resort often opens first—sometimes even in mid-November—and keeps lifts spinning into April or May. Most other ski areas stick to December through March.
Monthly Skiing Conditions:
- December: Early season, not all terrain is open yet
- January: Cold temps bring good snow buildup
- February: Best snowfall and deepest bases
- March: Longer days and spring skiing vibes
January averages 27°F during the day and drops to 10°F at night, which keeps the snow in great shape. February brings the most snow, but it’s still cold.
March is all about spring skiing. Days hit 40°F, so it’s a lot more comfortable—especially for beginners and families.
Top Months for Hiking and Lake Activities
June through August brings the best weather for hiking and hanging out on Lake Champlain. Highs usually land between 76°F and 81°F. Honestly, July feels like the sweet spot if you want the warmest water for swimming or water sports.
June kicks off the stretch of reliably warm days, but the lake water still feels a bit chilly if you’re thinking about taking a dip. Trails finally dry out after the muddy spring wraps up in May.
Summer Activity Conditions:
- June: Warm days (76°F), cool water, and plenty of daylight.
- July: Hottest month (81°F), probably your best bet for swimming.
- August: Still warm (79°F), and the lake hits its peak temperatures.
Lake Champlain usually feels its warmest in late July and August. If you love swimming, boating, or any water sports, these months are hard to beat. The lake’s size means it takes a while to warm up, but once it does, it stays nice for longer than you’d expect.
May works well for hiking, especially if you want to catch waterfalls at their best after all that snow melts. Swimming? Still too cold for most folks. September keeps things going with comfortable 70°F days, and you’ll notice the crowds thin out.
