- In New York, tree pollen peaks in spring (April), grass pollen in early summer (June), and weed pollen in late summer to early fall (September).
- Key allergens include tree pollen from oak, maple, and birch; grass pollen from ryegrass and Timothy grass; and weed pollen, especially from ragweed.
- Checking pollen forecasts, limiting outdoor time on high-pollen days, and using combination nasal sprays (e.g., Allermi) can help manage symptoms.
New York has stunning contrasts, from the bustling streets of Manhattan to the serene beauty of the Adirondacks and Finger Lakes. But as much as there is to love about this diverse state, allergy sufferers know that the changing seasons can bring their own set of challenges.
With pollen swirling through the air and allergens lurking in every corner, many people across New York State struggle with symptoms like sneezing, congestion, and itchy eyes.
The good news? Understanding when allergy season starts, peaks, and ends in 2025 can help you better prepare and manage your symptoms.
When is the Pollen Season in New York?
Pollen season in New York varies by region due to differences in local plants and climate, which affects each area in its own way.
In New York City and surrounding urban areas, pollen season can feel intense due to tree pollen in March, which then peaks in April.
Upstate New York has a similar pollen timeline but with distinct characteristics due to its extensive green spaces. Tree pollen, for instance, remains high in early spring, particularly from species such as oak and maple. However, grass pollen is especially high in late spring and early summer, and peaks in June.
Long Island typically follows the same seasonal trends but is affected by strong sea breezes that can disperse pollen widely across both urban and suburban areas. This means that while the timing of pollen peaks is similar to NYC, the distribution can lead to higher exposure levels for residents.
The Hudson Valley experiences spikes in both tree and grass pollen due to its proximity to forests and open areas. Tree pollen is prominent in early spring, while grass pollen peaks later in the season.
What are the Worst Months for Allergies in New York?
The worst months for allergies in New York generally fall between April and October, as this period covers the peak seasons for various types of pollen, such as tree pollen (spring), grass pollen (late spring to early summer), and weed pollen (late summer to fall).
Here’s a closer look:
- Spring (March to May). Tree pollen is the most significant allergen during spring, and levels peak in April. Common tree allergens in New York include oak, birch, and maple [*]. These trees are prevalent in areas like New York City parks and Upstate forests.
- Early Summer (May to July). As spring transitions into summer, grass pollen becomes the dominant allergen, particularly in June. Ryegrass and Timothy grass are common pollen sources across New York, and impact areas with large green spaces like Long Island and the Hudson Valley. Note that grass pollen is light and blows easily in the wind. So, even if there’s no grass near your home, you can still breathe in pollen from other places [*]
- Fall (August to October). Fall brings high levels of weed pollen, especially from ragweed, which peaks in September. Ragweed grows abundantly in rural and suburban areas but also affects urban regions as its lightweight pollen travels widely. This makes late summer and early fall some of the toughest months for allergies across New York.
When Does Pollen Season End in New York?
Pollen season generally tapers off by late October. Cooler temperatures in New York City significantly reduce pollen counts, particularly for tree and grass pollen.
In Upstate New York, pollen season usually ends by mid-October. As temperatures drop, tree and grass pollen levels decrease more rapidly compared to urban areas like New York City.
In Long Island, pollen season also tends to taper off by late October. The coastal breezes can help clear pollen, but levels drop significantly with the arrival of cooler weather.
In the Hudson Valley, pollen levels generally taper off by mid-October, which coincides with the cooling temperatures that diminish the presence of allergens.
Common Allergens in New York
Here are some of the most common allergens found across the state of New York:
- Oak
- Maple
- Birch (known for being highly allergenic)
- Ryegrass
- Timothy Grass
- Kentucky Bluegrass
- Ragweed
- Mold spores (thrive in any damp environment and can be a year-round allergen)
Keeping an eye on allergy symptoms caused by these culprits is important for taking timely action. Common signs include sneezing, itchy or watery eyes, runny nose, nasal congestion, and even fatigue.
How to Prepare for Seasonal Allergies in New York
Seasonal allergies can disrupt everyday life, especially during New York’s peak pollen seasons in spring and fall. The key to reducing your exposure and making your symptoms more manageable is to plan ahead.
Follow these preparation tips:
- Stay updated on local pollen forecasts to adjust outdoor activities accordingly. Limit time outdoors on high-pollen days, especially in the mornings when pollen levels are usually highest.
- Start allergy medications, like antihistamines, a few weeks before pollen season to help your body build up resistance. For more targeted relief, consider a combination nasal spray, such as Allermi, which includes multiple active ingredients — like an antihistamine, decongestant, and anti-inflammatory — that will ease symptoms more effectively.
- Wear sunglasses and a hat to protect your eyes and hair from airborne pollen. Wearing a mask can also help filter out allergens when pollen levels are especially high.
- Use HEPA filters in your home, especially in bedrooms and living areas, and keep windows closed to minimize indoor pollen.
- Pollen can easily enter your home from outside and cling to clothes, skin, and hair, as well as through open windows and doors. To reduce indoor pollen, shower and change clothes after spending time outside.
Take these steps in advance to help minimize the impact of seasonal allergies throughout New York’s pollen season.
