NY pollen report
New York Pollen Report
New York City's five boroughs sit in a dense corridor of street trees, parks, and waterfront vegetation — and despite the concrete, pollen counts here can be surprisingly severe. Central Park, Prospect Park, and the city's roughly 600,000 street trees put oak, maple, and plane tree pollen directly at street level, while ragweed thrives in vacant lots and along highways through late fall.

What drives allergies in New York
Trees: oak, maple, and London plane (March – May)
NYC's spring is driven by oaks (Quercus), maples (Acer), birch (Betula), and the London plane tree — the city's most common street tree. Peak tree season runs late March through May, with the worst days warm, dry, and breezy.
Grasses: June – July
Timothy and other lawn grasses pollinate heavily in early summer across parks, medians, and rooftops. Grass season is shorter than the South's but intense, often overlapping with the tail of tree pollen.
Weeds: ragweed (August – October)
Ragweed (Ambrosia) is New York's signature fall allergen. It grows aggressively in disturbed urban soil — construction sites, rail corridors, vacant lots — and counts stay high until the first frost.
Mold: summer humidity and fall leaves
Outdoor mold spores (Alternaria, Cladosporium) climb through the humid summer and spike again when fallen leaves pile up in October and November.
Pollen patterns in New York
In New York, tree pollen — including Birch, Oak, Maple — typically dominates from late winter through spring. Timothy grass is the most common warm-season pollinator, and Ragweed drives the largest fall pollen load.

Frequently asked questions
What is the pollen count in New York today?
PollyMap publishes real, microscope-verified pollen counts for New York City — measured from physical air samples, not modeled forecasts. The latest NYC report on this page shows current tree, grass, weed, and mold levels.
Is the pollen count high in NYC right now?
NYC pollen typically peaks from late March through May (tree pollen) and again from August through October (ragweed). Check the most recent measured report on this page to see exactly where levels stand today.
When is allergy season in New York?
New York's allergy season runs roughly March through October: tree pollen in spring, grass in early summer, and ragweed from late summer until the first frost. Mold rises with summer humidity and fall leaf litter.
Why are allergies so bad in New York City?
Hundreds of thousands of street trees and huge parks put pollen at street level, urban ragweed grows in every vacant lot, and the city's heat island effect can lengthen the season on both ends.
