Brooklyn, New York experiences intense seasonal pollen challenges driven by abundant urban parkland, warming climate trends, and high concentrations of allergenic tree species. Located in the northeastern United States with a humid subtropical climate, Brooklyn faces particularly severe tree pollen in spring, grass pollen in summer, and ragweed in fall. This guide provides detailed information about local pollen types, seasonal patterns, peak allergy months, monitoring resources, and effective management strategies to help Brooklyn residents minimize allergy symptoms throughout the year.
Understanding Pollen Count in Brooklyn
Pollen count measures the concentration of pollen grains per cubic meter of air, with levels categorized as low, moderate, high, or very high. When pollen counts reach high or very high levels, sensitive individuals typically experience symptoms including sneezing, runny nose, itchy eyes, respiratory discomfort, cough, and asthma exacerbation. Brooklyn's 2025 spring season recorded some of the most intense allergy levels in recent history, with pollen counts regularly hitting the very high range of 8.6 to 11.2.
Key Pollen Types and Recent Trends in Brooklyn
Brooklyn's allergy landscape is dominated by several highly allergenic pollen types that contribute to prolonged and intense seasonal suffering. The 2025 allergy season started earlier than usual and is lasting 20 days longer than historical averages, totaling 180 days across the Northeast region. Brooklyn experiences particularly high concentrations due to Prospect Park and neighborhood street plantings containing abundant allergenic tree species.
- Oak and Birch Pollen: These trees dominate spring allergen production, with oak producing heavy pollen loads and single birch trees releasing up to 5 million pollen grains that travel over 100 yards
- Maple and Plane Tree Pollen: Extremely allergenic pollen that travels for miles; together with oak, birch, and mulberry, these species comprise 71% of airborne pollen and 93% of estimated pollen production in NYC
- Grass Pollen: Timothy grass, Kentucky bluegrass, ryegrass, and Bermuda grass peak during June and July, with highest concentrations in Prospect Park and residential lawns
- Ragweed Pollen: NYC's most potent fall allergen, peaking in September and found abundantly in vacant lots, construction sites, and along roadways throughout Brooklyn
Climate warming trends are extending growing seasons and causing earlier spring onset, directly increasing total pollen exposure for Brooklyn residents. Urban sensitivity is amplified by air pollution interaction, making city residents more reactive to allergies despite having less vegetation than rural areas. Additionally, Brooklyn's urban heat island effect retains warmth, potentially extending pollen seasons and increasing overall pollen production from local trees and plants.
Seasonal Pollen Patterns in Brooklyn
Brooklyn experiences distinct pollen seasons with varying allergen types and intensity levels throughout the year.
- Spring (March to May): Dominated by tree pollen from oak, birch, maple, sycamore, elm, ash, and mulberry; May represents the highest overall pollen counts of the entire year
- Summer (May to August): Grass pollen season peaks during June and July with Timothy grass, Kentucky bluegrass, ryegrass, and Bermuda grass reaching maximum levels in parks and residential areas
- Fall (August to October): Weed pollen dominates with ragweed peaking in September at maximum allergenic levels, along with mugwort, pigweed, lamb's quarters, dock, and plantain
- Winter (November to February): Genuine break from outdoor pollen provides relief, though indoor allergens such as dust mites and mold remain active year-round
