Honestly, if you're looking at the weather in Williamsburg Virginia and just seeing "subtropical," you're missing the real story. Most people pack for a trip to the Historic Triangle thinking it’s going to be a mild breeze because it’s "The South." Then they get here in July and realize the humidity doesn't just sit in the air—it tries to start a conversation with you. Or they show up in January expecting a light sweater day and end up shivering on Duke of Gloucester Street because the damp chill from the James River cuts right through denim.
Basically, Williamsburg has a bit of a personality disorder when it comes to the forecast. You’ve got four very distinct seasons, but they don't always play by the rules. It's a place where you can see the blacksmiths at Colonial Williamsburg moving their entire operation indoors because the heat index hit $104^\circ\text{F}$, only to have a dusting of snow turn the whole town into a literal Christmas card three months later.
Why the weather in Williamsburg Virginia is weirder than you think
It’s all about the water. You’re tucked right between the York and James rivers, and the Chesapeake Bay is basically your neighbor. This means the humidity stays high almost year-round. In the winter, that moisture makes $40^\circ\text{F}$ feel like $25^\circ\text{F}$. In the summer, it makes $90^\circ\text{F}$ feel like you’re walking through a warm soup.
Take today, for instance. It's Sunday, January 18, 2026. If you’re standing outside right now, it’s about $33^\circ\text{F}$, but with the wind coming out of the northwest at 9 mph, it "feels like" $25^\circ\text{F}$. It’s cloudy, and there’s a 100% chance of rain and snow throughout the day. That’s classic Williamsburg winter—damp, gray, and just cold enough to make you crave a hot cider from Chowning's Tavern.

Breaking down the seasons (The honest version)
The Summer "Steam Room" (June–August)
July is the hottest month, with average highs around $90^\circ\text{F}$. But averages are liars. You’ll regularly see days where the mercury pushes toward $98^\circ\text{F}$. If you’re heading to Busch Gardens, do yourself a favor: go early. By 2:00 PM, the pavement is a griddle. This is the wettest time of year, too. August actually leads the pack with over 5 inches of rain on average, usually delivered in those violent, 30-minute afternoon thunderstorms that come out of nowhere and disappear just as fast.
The Fall "Sweet Spot" (September–November)
This is when the weather in Williamsburg Virginia actually behaves. October is arguably the best month to visit. The humidity drops, the sky turns that specific shade of "Virginia Blue," and the highs hover around $72^\circ\text{F}$. It’s the clearest month of the year, with sunny skies about 63% of the time. If you want to see the leaves change, aim for the last week of October or the first week of November.
The Winter "Damp Chill" (December–February)
January is the coldest stretch. Highs usually hit about $50^\circ\text{F}$, and lows drop to $33^\circ\text{F}$. Snow isn't a constant, but when it happens, it's beautiful. Seeing the colonial architecture draped in white is worth the cold toes. Just know that the town basically pauses when more than two inches falls.

The Spring "Pollen Explosion" (March–May)
Spring is gorgeous but messy. Temperatures climb from the $60\text{s}$ in March to the high $70\text{s}$ by May. Everything blooms at once. If you have allergies, bring your meds—the yellow pine pollen covers every car in town for about three weeks.
Practical survival tips for the local climate
You’ve gotta layer. Even in the summer, the air conditioning in the museums and taverns is set to "Arctic." You'll be sweating outside and seeing your breath inside.
- Footwear matters: You’re going to be walking on brick paths and gravel. When it rains, those bricks get slick. When it’s hot, they radiate heat. Wear broken-in sneakers, not flip-flops.
- The Poncho Rule: Don't bother with an umbrella if you're at a theme park or walking the historic area. The wind will just flip it. Grab a cheap poncho. It's easier to stuff in a bag when the sun comes back out ten minutes later.
- Hydration isn't a suggestion: In the summer, the "feels like" temperature is the only number that matters. If the humidity is $80%$ and it's $90$ degrees, you are losing water faster than you think.
What’s happening right now?
If you're looking at the window today, Sunday, January 18, the high is $43^\circ\text{F}$ with a low of $26^\circ\text{F}$. The humidity is sitting heavy at $89%$. Tomorrow, Monday, things clear up significantly with a high of $44^\circ\text{F}$ and full sun, but that low is going to bite at $23^\circ\text{F}$. It’s a good week for indoor history.

Check the UV index even in winter. It’s a $0$ today because of the clouds, but it jumps to a $3$ tomorrow. You can still get a "windburn" or a light sun-kissed look if you’re out on the water or walking the battlefields all day without protection.
Actionable Next Steps
Check the "feels like" temp, not just the high. If the humidity is over $70%$, add 5 degrees to your mental forecast.
Pack a dedicated "rain kit" including a lightweight waterproof shell and extra socks. Nothing ruins a colonial tour faster than wet wool socks.
Book outdoor activities like carriage rides or the Jamestown ferry for the morning hours during summer months to avoid the $3\text{:00 PM}$ heat spike and thunderstorm window.
Watch the wind direction. A north wind in Williamsburg almost always brings a sharp drop in temperature within two hours, regardless of what the sun is doing.
