So, you’re looking at your phone and wondering what's the weather in dc right now. Honestly, it depends on which five minutes you're asking about. If you are standing on the National Mall today, January 15, 2026, you’re probably feeling a pretty crisp bite in the air. We are looking at a high of 32°F and a low dipping down to 20°F tonight.
It’s sunny, which is a bit of a lie. The sun is out, but that wind coming from the west at 16 mph makes it feel more like the mid-20s.
Washington, D.C. has this reputation for being a swamp, and while that’s mostly a political metaphor, the humidity here is very real. Even in the dead of winter, the air isn't always "dry cold." It’s a damp, bone-chilling cold that makes you want to live inside a Smithsonian museum until April.
The Reality of What's the Weather in DC During Winter
If you were here yesterday, you saw a high of 53°F. Today? Barely freezing. That’s DC for you. The city is currently in a six-day stretch—the coldest of the year—where the average high usually bottoms out around 44°F.
People always ask me if it actually snows here. The short answer is: sometimes, but it’s usually a mess. We are currently watching a "conversational" snow chance for Saturday, January 17. By conversational, I mean the kind of flurries that make people post on Instagram but don't actually require a shovel.
The big "Snow potential index" is currently sitting at a 1 out of 10. Basically, don't buy out the milk and bread aisles at Harris Teeter just yet.

Why DC Weather Is So Unpredictable
The District sits in a weird geographical "Goldilocks zone" that isn't particularly just right. We’re tucked between the Appalachian Mountains to the west and the Atlantic Ocean to the east.
When a cold front hits those mountains, the air gets trapped. This is called "cold air damming." It’s why you might see rain in Alexandria but a full-blown ice storm in Bethesda.
- The Jet Stream factor: When the jet stream dips, we get that Arctic air from Canada.
- The Chesapeake Influence: The bay keeps us slightly warmer than the inland suburbs.
- Urban Heat Island: Downtown DC is often 3-5 degrees warmer than Dulles Airport because of all the concrete and traffic.
A Month-by-Month Cheat Sheet
If you’re planning a trip and trying to figure out what's the weather in dc later this year, here is the raw truth.
January is the coldest. Most of the "real" snow happens in February, though. February is actually the driest month, but when it does precipitate, it's often the white stuff.
March is a gamble. One day it’s 70 degrees and you’re walking the Tidal Basin in a t-shirt; the next day, a Nor'easter kills half the cherry blossom buds.

April and May are the "sweet spots." This is when the city looks like a movie set. Highs are in the 60s and 70s. Just bring an umbrella. May is historically one of the wettest months, often seeing over 4 inches of rain.
Survival Guide for DC Summers
July is, frankly, brutal.
The average high is 89°F, but the humidity can push the "feels like" temperature over 100°F.
I’ve seen tourists collapse near the Lincoln Memorial because they underestimated the swamp. You’ll see locals moving from one air-conditioned building to the next like they're navigating a minefield.
September is the comeback kid. The humidity breaks, the crowds thin out, and the evenings are perfect. If I were you, I’d visit in October. It’s dry, crisp, and the fall foliage along the Rock Creek Park trails is world-class.
What Most People Get Wrong About DC Weather
The biggest misconception? That DC is a "southern" city with mild winters.
Tell that to the people who lived through the "Knickerbocker Storm" of 1922 (28 inches of snow) or the 2010 "Snowmageddon."

We also get weird weather phenomena like "thundersnow." It’s rare, but it happens when the atmosphere is unstable enough during a massive blizzard.
Another thing: the rain here doesn't usually last all day. In the summer, we get these violent, 20-minute thunderstorms at 4:00 PM that feel like the end of the world, and then the sun comes back out like nothing happened.
Actionable Advice for Your Visit
- Layer like a pro: In the spring and fall, the temperature can swing 30 degrees between noon and 8:00 PM.
- Check the Capital Weather Gang: If you want the real scoop, skip the generic apps and read the Washington Post’s weather blog. They understand the local microclimates better than anyone.
- Hydrate in the Summer: This sounds like "mom advice," but the DC humidity will drain you faster than you think.
- Museums are your friend: If the weather turns, the Smithsonian museums are free and climate-controlled. Use them as "weather shelters."
Looking at the forecast for the rest of this week, Friday will stay chilly in the mid-30s. If you’re heading out tonight, bundle up. That 20°F low is going to feel every bit as cold as it sounds once that sun goes down behind the Washington Monument.
To stay prepared, keep a compact umbrella in your bag at all times—DC weather doesn't give warnings, it just happens.
