Understanding the distinction between seasonal allergies vs. perennial allergies is crucial for effective treatment and long-term relief — especially in a place like New York City, where allergens can be constant and varied. Not all allergies are created equal. Some strike only during specific times of the year, while others seem to linger year-round with no relief in sight.
If you’re constantly sneezing, congested, or battling itchy eyes, this guide will help you identify whether your symptoms are seasonal or perennial — and what steps you can take to manage them effectively.

Seasonal allergies, also known as hay fever or seasonal allergic rhinitis, are triggered by allergens that appear at certain times of the year. These allergens are typically airborne pollens from:
These symptoms usually intensify during high pollen count days and may last weeks or months, depending on the season and your specific triggers.
Perennial allergies occur year-round and are caused by continuous exposure to indoor allergens. These may include:
Because the exposure is constant, symptoms tend to be milder but more persistent than those from seasonal allergies.
| Feature | Seasonal Allergies | Perennial Allergies |
|---|---|---|
| Timing | Specific seasons (spring, summer, fall) | Year-round |
| Common Triggers | Pollen (trees, grasses, weeds) | Dust mites, pet dander, mold |
| Onset | Sudden during allergy season | Chronic and ongoing |
| Location | Mostly outdoors | Mostly indoors |
| Relief Strategies | Pollen avoidance, antihistamines, nasal sprays | HEPA filters, frequent cleaning, allergen-proof bedding |
Accurate allergy testing can confirm whether your symptoms are triggered by seasonal allergens, perennial allergens, or both. Tests may include:
