Pollen season in New York City typically begins in late February or early March, when trees start releasing pollen, and can last through late October. In Queens, spring allergy season peaks in April and May due to heavy tree pollen from oak, birch, maple, and elm. Grass pollen follows in June, and ragweed drives fall allergies from August through October. Climate change has extended the Northeast allergy season to approximately 180 days, making early preparation essential for Queens residents in Flushing, Astoria, Jackson Heights, Forest Hills, Bayside, and nearby communities.
When Does Allergy Season Actually Start in New York?
If you’ve lived in Queens for any length of time, you probably already have a sense of when your nose starts to run and your eyes start to itch. But when is allergy season in New York in a precise, practical sense? The honest answer is that it starts earlier than most people expect.
Tree pollen is usually the first trigger, and it can begin circulating as early as late February in a mild winter. By mid-March, pollen counts are climbing. Come April, they’re often at their highest point of the entire year. Oak is the dominant culprit from April through May, but birch trees, which are common throughout Queens neighborhoods, start releasing pollen in March and keep going through April. Maple, elm, sycamore, and ash trees add to that load simultaneously. For someone sensitive to multiple trees, the early spring window can feel relentless.
What makes Queens a bit different from, say, a suburban town is the density. The “urban canyon” effect means tall buildings along streets like Main Street in Flushing or Northern Boulevard trap pollen at pedestrian level rather than letting it disperse. You can be nowhere near a park and still be heavily exposed. Flushing Meadows Corona Park alone is a significant pollen contributor, with flowering pear trees, redbuds, maple, and horsechestnut trees all blooming through April and May. Kissena Park and Alley Pond Park add to that. So does every tree-lined residential block from Bayside to Jackson Heights.
The Three Waves of Pollen: A Season-by-Season Breakdown
When is allergy season in New York? The more useful way to think about it is that there are actually three distinct waves, not one season.
The first wave is tree pollen, running from late February through late May. This is when most people with seasonal allergies feel the worst. Pollen counts during peak tree season in NYC regularly hit “very high” to “extremely high” levels, with concentrations recorded between 8.6 and 11.2 on the scale used to measure allergen density in the air. For people sensitive to oak, birch, or maple, even a few hours outdoors on a dry windy morning in April can mean hours of symptoms.
The second wave is grass pollen, which starts to rise in late May and peaks in June, typically tapering off by early August. Timothy grass, Kentucky bluegrass, ryegrass, and Bermuda grass are the main sources. One of the tricky things about grass pollen is that it’s lightweight and travels easily, so you can be affected even if you live in a dense urban neighborhood with very little visible grass nearby. Pollen blown in from Long Island and the surrounding region adds to what’s already being generated locally.
The third wave is weed pollen, dominated by ragweed. This runs from mid-August through late October, with September being the peak. A single ragweed plant can produce an enormous quantity of pollen over a season, and those particles travel far on the wind. Queens residents in Forest Hills and Jamaica, where there’s more vacant land and green space, may notice this wave more intensely, but no neighborhood is immune.
The overlap periods are where things get particularly difficult. Late April into May is when tree pollen and early grass pollen often run together. If you’re sensitive to both, that 4 to 6 week window can be overwhelming even with medication.
Why Are Allergies Getting Worse in New York?
This isn’t just perception. The data is clear: when is allergy season in New York has shifted meaningfully over the past few decades. Since 1970, NYC’s average growing season has extended by more than three weeks. The 2025 spring allergy season in the Northeast was expected to last approximately 180 days, about 20 days longer than the historical average, according to physicians quoted by CBS News. That’s not a small change.
Climate change drives this in two ways. Warmer temperatures mean the final frost arrives earlier in spring and the first frost comes later in fall, giving plants a longer window to produce pollen. Elevated CO2 in the atmosphere also amplifies pollen production directly, making plants generate more of it. The result is that even people who managed their allergies reasonably well for years are finding that what used to work isn’t quite cutting it anymore.
Urban factors compound the problem further. NYC’s heat island effect makes Queens and the other boroughs measurably warmer than surrounding suburban areas, which accelerates tree and grass growth. Air pollution from traffic and construction irritates airways that are already inflamed by pollen, making symptoms more severe even at the same pollen exposure levels.
Practical Steps to Get Through Pollen Season in Queens
Most of this comes down to timing and awareness.
- Check the pollen count every morning before heading out. Weather apps, AccuWeather’s allergen forecast for Flushing, and the AAAAI’s National Allergy Bureau all provide local counts. High count plus low humidity plus wind equals a rough day.
- Stay indoors during the early morning hours on high-pollen days. Pollen levels tend to peak between roughly 5 AM and 10 AM. If you commute on foot or by bike, shifting that timing even slightly helps.
- Keep windows closed during peak pollen periods, even in spring when the weather is pleasant. A HEPA air purifier running indoors makes a significant difference.
- Shower and change clothes when you get home, especially on dry windy days. Pollen clings to hair and clothing and will continue affecting you indoors if you don’t remove it.
- If you have a pet that spends time outdoors, wipe them down when they come inside. Their fur collects pollen just like your jacket does.
- Start antihistamines about one to two weeks before you typically feel your first symptoms, rather than waiting until you’re already miserable. Nasal corticosteroid sprays work best when used consistently, not just on bad days.
- Rain days are your friend. Pollen counts drop after a good rain. That’s a good time to open the windows and get some fresh air before they rise again.
When to Stop Managing Symptoms on Your Own
Over-the-counter antihistamines and nasal sprays work well for a lot of people, but there are times when self-managing just isn’t enough, and waiting it out can make things worse.
If your symptoms have been going on for more than a week or two despite using standard medications, it’s worth getting evaluated. Sometimes what feels like allergies is actually a sinus infection layered on top of allergies, and that won’t respond to antihistamines. A doctor can tell the difference and prescribe the right treatment.
If you’re experiencing any difficulty breathing, tightness in your chest, or wheezing along with your allergy symptoms, don’t wait. Those can be signs that allergies are triggering asthma. NYC’s Department of Health data shows that asthma-related emergency department visits spike in April and May, precisely because people underestimate how much tree pollen can affect the airways. Wheezing and chest tightness warrant same-day evaluation.
If your eyes are significantly swollen, crusted, or producing discharge beyond typical watering, you may have allergic conjunctivitis that needs prescription treatment. And if you’ve developed hives or any skin reaction alongside your allergy symptoms, see someone that day.

What Doctors Can Actually Do for Seasonal Allergies
There’s a range of options beyond what you’ll find at the pharmacy. Prescription-strength nasal corticosteroid sprays, combination antihistamine/decongestant medications, and leukotriene receptor antagonists (like montelukast) are commonly used for more significant symptoms. Prescription eye drops for allergic conjunctivitis provide relief that OTC drops often can’t match.
For patients who want more than symptom management, referral to an allergist for skin testing can identify exactly which pollens are triggering your immune system. That matters because someone reacting to birch pollen may need a different approach than someone whose main problem is ragweed. Allergy immunotherapy, either shots or sublingual drops, can meaningfully reduce sensitivity over time rather than just suppressing symptoms each season.
The important thing is that urgent care visits for allergy symptoms don’t have to be reserved for emergencies. Getting an evaluation when your symptoms are new, changing, or uncontrolled is exactly what primary care and urgent care for seasonal allergies is for.
A Note on Distinguishing Allergies from Other Conditions
One thing that comes up frequently in this time of year is confusion between allergies, colds, and COVID-19. Allergies typically produce sneezing, clear nasal discharge, itchy or watery eyes, and nasal congestion, but not fever, body aches, or sore throat. A cold will usually resolve within 7 to 10 days. Allergies persist for weeks and track closely with pollen season. If you’re not sure which you’re dealing with, an urgent care for allergy visit can help sort that out and get you the right treatment for what’s actually happening.

자주 묻는 질문
- When does pollen season start in New York City? Pollen season in New York City typically starts in late February or early March, when trees begin releasing pollen. In warmer winters, it can begin a few weeks earlier. Tree pollen is usually the first trigger, with peak levels occurring in April and May.
- When is allergy season in New York the worst? The worst period for most allergy sufferers in New York is April through May, when tree pollen from oak, birch, and maple trees is at its peak. A secondary difficult period is September, when ragweed peaks and drives fall allergy symptoms.
- What trees cause the most allergies in Queens, NY? In Queens, the most allergenic trees are oak, birch, maple, elm, sycamore, and ash. Birch trees are particularly common in residential neighborhoods throughout the borough. Oak is the single dominant allergen across all five NYC boroughs from April through May.
- How long does allergy season last in New York? Allergy season in New York can run from late February all the way through late October, when the first hard frost arrives and kills remaining pollen sources. Due to climate change, the Northeast allergy season now lasts approximately 180 days, about 20 days longer than historical averages from a few decades ago.
- Why are my allergies so bad in New York compared to other places I’ve lived? New York City has a combination of factors that intensify allergy symptoms: the “urban canyon” effect traps pollen at street level between tall buildings, the urban heat island effect extends the growing season, air pollution compounds airway inflammation, and there is a high density of pollen-producing trees in parks and along streets throughout all boroughs.
- What is the difference between a cold and seasonal allergies? Allergies typically cause sneezing, clear nasal discharge, itchy or watery eyes, and nasal congestion without fever, sore throat, or body aches. Symptoms persist for weeks or months and correlate with pollen season. A cold usually resolves within 7 to 10 days and may cause fever, sore throat, and body aches, which allergies do not.
- Should I go to urgent care for allergy symptoms? Yes, visiting urgent care for allergies makes sense when over-the-counter medications are not controlling your symptoms, when symptoms are interfering with daily life or sleep, when you have difficulty breathing or wheezing, when you suspect a sinus infection on top of allergies, or when eye symptoms are severe. Urgent care providers can evaluate your symptoms, prescribe appropriate medications, and refer you to an allergist if needed.
- Can seasonal allergies trigger asthma in Queens residents? Yes. Seasonal allergies and asthma frequently occur together, and high pollen counts are a known trigger for asthma flare-ups. NYC Department of Health data shows that asthma-related emergency department visits spike in April and May during peak tree pollen season. If you have both conditions, managing allergies proactively during pollen season is especially important.
- What medications are used to treat seasonal allergies? Common treatments include oral antihistamines (such as cetirizine, loratadine, or fexofenadine), nasal corticosteroid sprays, decongestants, and antihistamine eye drops. Prescription options include stronger nasal sprays, leukotriene receptor antagonists, and for long-term management, allergy immunotherapy (shots or sublingual drops).
- When should I start taking allergy medication in New York? For spring allergies, ideally begin taking antihistamines and nasal corticosteroid sprays one to two weeks before your typical symptom onset, which in Queens means late February or early March. Nasal steroid sprays in particular take several days of consistent use to reach full effectiveness, so starting early rather than reacting to symptoms gives you much better control throughout the season.
