You’re standing on Duke of Gloucester Street. The clip-clop of horse-drawn carriages rings out against the brick. It feels like 1774. But then, a bead of sweat rolls down your neck, or perhaps a gust of wind nearly steals your tricorn hat. Suddenly, the 21st-century reality of colonial williamsburg va weather hits you.
Planning a trip here isn't just about booking a room at the Williamsburg Inn. It’s about outsmarting the Tidewater climate. Most folks assume Virginia is "mild." Honestly? That’s a bit of a stretch. Depending on the week, you might face oppressive humidity that feels like a wet wool blanket or a crisp, bone-chilling breeze coming off the York River.
I’ve seen tourists show up in July wearing heavy denim. Big mistake. Huge.

The Humidity Factor: Summer in the Tidewater
Summer in Williamsburg is legendary. Not always for the right reasons. Between June and August, the average highs hover around 85°F to 90°F. That doesn't sound too bad until you factor in the dew point.
The humidity here is "muggy" to "oppressive" for about 70% of the summer. Basically, you’re walking through soup.
July is the hottest month, often peaking at 91°F. If you’re visiting during this window, the shade of the massive oak trees is your best friend. August is actually the wettest month of the year, averaging over 5 inches of rain. These aren't usually day-long drizzles; they are violent, 20-minute afternoon thunderstorms that clear the streets and leave the air even steamier than before.
Pack linen. Seriously.
Survival Tips for the Heat
- The 10 AM Rule: Get to the historic area early. Most trade shops are small, and while some have modern HVAC tucked away, many rely on cross-breezes.
- Hydration Stations: There are water bottle refill stations near the Visitor Center and the Museums. Use them.
- The Art Museums: The DeWitt Wallace Decorative Arts Museum is underground. It is gloriously air-conditioned. Save it for 2:00 PM when the sun is at its most vengeful.
The "Secret" Seasons: Why Spring and Fall Win
If you ask any local when the best colonial williamsburg va weather occurs, they’ll point to two very specific windows.
First, there’s the late March to May stretch. April is a dream. The highs are around 70°F, and the gardens are exploding with tulips and apple blossoms. It’s the "Goldilocks" zone—not too hot, not too cold. You can walk the three-mile loop of the Historic Area without breaking a sweat.
Then there’s the "Second Spring." That’s what I call October.
October is statistically the clearest month of the year. The sky is a deep, piercing blue about 63% of the time. The humidity finally breaks, and the leaves on the maples start to turn. Highs sit right around 72°F. It’s perfect for the evening ghost tours because there’s just enough of a chill to make the stories feel real, but not enough to make your teeth chatter.
Winter: Does It Actually Snow in Williamsburg?
Short answer: sometimes.
Williamsburg averages about 5 inches of snow per year. It’s not a lot. When it does snow, the historic area looks like a literal Christmas card. The red brick buildings against the white powder? Incredible.
But usually, winter (December through February) is just cold and damp. January is the coldest month, with average lows hitting 32°F and highs struggling to reach 50°F. It feels colder than the thermometer says because of the moisture in the air. That "damp cold" sinks into your bones.
The Grand Illumination Weather
The biggest event of the year is the Grand Illumination in December. Thousands of people gather for fireworks and candles.
Check the forecast for wind. Because Williamsburg sits on a peninsula between the James and York Rivers, the wind can whip through the open pastures behind the Peyton Randolph House. If it’s 40°F with a 15 mph wind, you’ll want those hand warmers. Trust me.
A Quick Look at the Numbers (Averages)
To give you a better idea of what to pack, here’s how the year typically breaks down. These aren't just guesses; they’re the hard averages that define the region.
Winter (Dec–Feb): Highs of 50°F to 55°F. Lows of 32°F to 37°F. Expect about 3 inches of rain/sleet per month.

Spring (Mar–May): Highs jump from 60°F in March to 78°F in May. This is the windiest time, especially April, which sees gusts averaging 15 mph.
Summer (Jun–Aug): Highs of 85°F to 90°F. July and August are the "sweat months." Rainfall is highest here, often hitting 5 inches in August.
Fall (Sep–Nov): September starts warm (82°F) but drops fast. By November, you’re looking at a crisp 62°F. This is the driest season, which is great for outdoor dining at the taverns.
Historic Perspective: Jefferson’s Weather Logs
We actually know a lot about colonial williamsburg va weather because Thomas Jefferson was a total weather nerd. While he was a student at William & Mary in the 1760s, he started keeping meticulous logs.
He noted that the summers felt cooler back then, with highs rarely breaking 80°F. However, modern researchers at the William & Mary Keck Lab found a funny detail: Jefferson took his readings indoors in unheated rooms on the north side of buildings.
He wasn't recording the "real" temperature; he was recording how well-insulated 18th-century brick was.

Even back then, the weather dictated everything. It determined when the tobacco was planted and when the "Public Times" (court sessions) were held. If the roads were too muddy from a spring thaw, the lawyers and politicians couldn't make it to town.
What to Actually Pack
Forget the fashion show. You need utility.
- Footwear: Those cobblestones and gravel paths are brutal. Wear broken-in walking shoes. If it rains, the paths turn into a fine, sandy mud.
- Layers: Especially in the shoulder seasons. A 45°F morning can easily turn into a 70°F afternoon.
- The Umbrella vs. Poncho Debate: Go with a compact umbrella. A plastic poncho in Virginia humidity is just a portable sauna. You’ll be wetter from your own sweat than from the rain.
- Sunscreen: Even in the winter. The historic area is very open, and the sun reflects off the white-painted trim of the houses.
Actionable Insights for Your Trip
- Check the Dew Point: Don't just look at the temperature. If the dew point is over 65°F, it's going to feel sticky. If it's over 70°F, plan for indoor activities.
- Book Taverns Early for Summer: Places like King’s Arms or Chowning’s Tavern have thick brick walls and stay surprisingly cool, but they fill up fast when people are trying to escape the sun.
- Monitor the Tropics: September is peak hurricane season. While Williamsburg is inland, a tropical storm in the Atlantic can bring three days of non-stop rain and wind to the Peninsula.
- The "Slow" Season Advantage: If you don't mind the cold, late January and February have the lowest crowds. You’ll have the trade shops all to yourself, and the interpreters are often more chatty because they aren't rushed.
Before you head out, check the local National Weather Service office (Wakefield, VA) for the most accurate short-term forecast. They handle the specific micro-climate of the Virginia Peninsula much better than the generic national apps. If they mention a "Nor'easter," expect wind and flooding on the Colonial Parkway. Otherwise, just bring your walking shoes and a bit of patience for the Virginia humidity.
