It is freezing. Seriously, the wind chill is biting at your face, yet somehow, your nose is running and your eyes feel like they’ve been rubbed with sandpaper. You might be thinking it’s a cold. Or maybe the flu. But honestly, if you're looking at the data for pollen in dc today, you might be surprised to find that the invisible yellow dust isn't waiting for the cherry blossoms to wake up.
Most people think allergy season starts in March. They're wrong.
In Washington DC, the "season" has basically become a year-round event. Today, Friday, January 16, 2026, the actual pollen levels are technically sitting in the low to moderate range, but that "moderate" tag is doing a lot of heavy lifting for people with sensitive sinuses. While the grass is dormant and the ragweed is a distant autumn memory, we are seeing early movement from the heavy hitters: trees. Specifically, the Juniper and Cedar families.
The January Surprise: What’s Actually in the Air?
It feels weird to talk about pollen when there’s a threat of snow in the forecast. But trees like the Eastern Red Cedar (which is actually a juniper, because plant names are confusing) don't care about your calendar. They release pollen as soon as there’s a slight bump in temperature or a particularly dry, windy day.
If you've lived in the District for more than a few years, you’ve probably noticed the "yellow haze" coming earlier every year. You aren't imagining it. A study by Climate Central recently pointed out that DC’s allergy season is about 20 days longer than it was in the 1970s. That’s nearly three weeks of extra sneezing.

Why the "Low" Count Still Feels Terrible
Pollen counts are often reported as grains per cubic meter.
- 0-14: Low
- 15-89: Moderate
- 90+: High
But here’s the kicker: if you are specifically allergic to Juniper or Elm, a "moderate" count of 40 can feel like a "high" count of 500 of something you aren't sensitive to. Today, the dominant pollen types in the DMV area are:
- Juniper/Cedar: The main culprit right now. These hardy evergreens are the first to fire.
- Maple: Some early-budding species are starting to stir in the warmer microclimates of the city.
- Elm: Just starting to show up in trace amounts.
The "heat island" effect of DC makes this worse. Because the concrete in areas like DuPont Circle or Chinatown holds onto heat, the trees in the city often wake up days or even weeks before the trees out in Loudoun County or further into Maryland.
The "False Spring" Trap
We get these weird days in January where the sun comes out, the temperature hits 50 degrees, and everyone heads to Rock Creek Park. It’s great for the soul, but it’s a disaster for the immune system. When the ground thaws even slightly, those trees see it as a green light.
Then it gets cold again. The pollen doesn't just disappear; it settles. It sits on your car, your coat, and your hair. Then you walk inside, turn on the heater, and blow those particles all over your apartment.
Is it a Cold or Allergies?
Since it's January, everyone is coughing. You’ve gotta look for the "itch factor."

- Itchy eyes/throat? Almost certainly allergies.
- Aches and fever? That’s a virus.
- Clear mucus? Likely pollen.
- Thick, yellow/green stuff? You’ve probably got a cold.
Honestly, the overlap is annoying. But if you take an antihistamine and feel better in an hour, you've found your answer.
How to Handle Pollen in DC Today
If you're feeling the hit today, you don't have to just suffer until June. There are a few very specific things about DC's geography that change how you should manage this.
The Wind is Your Enemy. Today has some decent gusts. Wind doesn't just bring new pollen in; it kicks up the stuff that’s already on the ground. If you’re walking near the Mall or any of the open circles, you’re walking through a literal vortex of allergens.
Wash Your Hair. This sounds like "mom advice," but pollen is sticky. It’s designed to stick to bees and wind; your hair is a perfect trap. If you’ve been outside today, shower before you hit the pillow. Otherwise, you’re just rubbing January tree dust into your pillowcase all night.
Check the AQI. Often in DC, pollen levels and air quality issues (like fine particulate matter) travel together. Today’s air quality is "Good," but the combination of cold, dry air and trace pollen can mimic a much higher allergy load by irritating your bronchial tubes.
Actionable Steps for DC Residents
Don't wait for the official "Spring" forecast to start your defense.
- Start your meds now. If you use Flonase or similar nasal steroids, they take a few days—sometimes a week—to reach full effectiveness. If you wait until the oak trees explode in April, you’ve already lost the first half of the battle.
- HEPA is your friend. Most old DC rowhomes have "character," which is code for "drafty windows." A small HEPA air purifier in the bedroom can make a massive difference when the Juniper count is climbing.
- The Mask Habit. Remember those masks we all have in our junk drawers? If you’re doing yard work or walking the dog on a high-wind day in DC, wearing one for 20 minutes actually filters out the majority of large pollen grains. It's not just for viruses.
- Local Honey is a Myth (Mostly). You’ll hear people at the Eastern Market telling you to eat local honey to build immunity. While it’s delicious, bees mostly collect pollen from bright flowers, not the wind-blown tree pollen that causes 90% of DC’s allergy problems. Eat the honey because it’s good, but keep your Claritin handy.
The reality is that pollen in dc today is a preview of the coming months. We are seeing a shift where "allergy season" is less of a season and more of a permanent resident of the Potomac basin. Keep an eye on the daily counts from the National Allergy Bureau (NAB) for the most accurate local data, as they use actual physical counting stations rather than just computer models.
