Why are my allergies worse on Long Island?

Common Long Island allergy triggers
Some of the most common allergy triggers on Long Island include:
Oak and birch trees
Long Island has a large number of oak and birch trees, both of which release large amounts of pollen in the spring. These pollen grains are small and lightweight, making them easy to spread through the air.
Ragweed
Ragweed is a major problem in the late summer and early fall. Just one plant can produce over a billion grains of pollen, which often blow in from open fields and roadsides.
Mold spores
Because Long Island has many older homes, shaded yards, and wet basements, mold spores are a year-round concern. These tiny particles grow on damp wood, leaves, and in bathrooms or basements.
Grass pollen
In late spring and early summer, grass pollen becomes a major issue. Lawns, parks, and golf courses all contribute to the amount of pollen in the air.
How the coastal climate makes it worse
Living near the ocean has its perks, but when it comes to allergies, the coastal environment can make things more difficult. Here's how:
Humidity
The air near the coast is often moist and humid, especially in the summer. This extra moisture helps mold and mildew grow more easily both indoors and outside. If your home has poor ventilation or older windows, humidity can lead to more indoor allergens.
Wind
Sea breezes can carry pollen, dust, and mold spores across neighborhoods. Even if you don’t have trees or grass right near your home, wind can bring allergens from blocks or even miles away.
Salt air
Salt in the ocean air can irritate already-inflamed nasal passages. For people with allergies or sinus problems, this can make symptoms feel worse.
What time of year is allergy season on Long Island?
Allergy season on Long Island isn’t just limited to spring. In fact, different allergens peak at different times throughout the year:
- Spring (March–May): Tree pollen from oak, birch, maple, and elm is the most common trigger.
- Summer (June–August): Grass pollen peaks, along with increasing mold in the humid weather.
- Fall (September–October): Ragweed becomes the biggest issue, especially in open fields and wooded areas.
- Winter (November–February): While outdoor allergens die down, indoor allergies from dust mites, pet dander, and mold become more noticeable.
That means allergy symptoms can be caused by different allergens all year long.
What you can do to find relief
The good news is that you don’t have to suffer through allergy season after allergy season. Here are a few practical steps you can take to feel better:
Keep windows closed
It might be tempting to let in the fresh air, but open windows invite pollen and mold spores inside.
Use a HEPA filter
High-efficiency air filters in your home can help trap pollen, mold, and dust. Look for filters labeled “HEPA” and change them regularly.
Shower after being outdoors
Pollen can stick to your hair, clothes, and skin. A quick shower can rinse it away and keep it from spreading through your home.
Avoid outdoor chores during peak pollen times
Early mornings are often the worst time for pollen. Try to mow the lawn or garden in the late afternoon or evening if you have to do it yourself.
Try over-the-counter treatments
Antihistamines, nasal sprays, and saline rinses can reduce symptoms. Be sure to follow the directions and talk to your doctor if your symptoms continue.
When to see an allergy specialist
If your allergies last more than a few weeks, or if they’re stopping you from enjoying daily life, it may be time to see a professional.
You should see a specialist if:
- Your symptoms aren’t improving with over-the-counter medications
- You experience frequent sinus infections
- You have asthma or trouble breathing
- You want to know exactly what you’re allergic to
At an allergy clinic, testing can help pinpoint your exact triggers. Treatment options like immunotherapy (allergy shots or drops) and in-office procedures like Clarifix® can also provide long-term relief. Clarifix® is a simple, non-surgical treatment that targets overactive nasal nerves to reduce congestion and runny nose caused by chronic rhinitis.
