New York's pollen season opens with maple and elm from late February, followed by oak and birch through April and May. Grass pollen peaks through June and July, with ragweed dominating from August through October. The city's continental climate produces distinct seasonal peaks, while the density of urban development means local parks and street trees are the primary sources for most residents.

The New York pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in New York, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
