New York Riverside Park runs along the Hudson River on the Upper West Side, where cottonwood, willow, and introduced ornamental trees are the main pollen sources along this classic Manhattan Hudson riverside park. The Hudson River position means onshore winds can frequently disperse pollen, while birch peaks through April and May, grass peaks through June and July, and mugwort extends into September throughout this beloved Upper West Side Hudson riverside park.

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.
