New York Van Cortlandt Park features the park's extensive oak, maple, and birch woodland as the main pollen sources in this large Bronx park with forest, meadow, and wetland habitats. The varied terrain creates locally different pollen exposure across the woodland and open areas, while birch peaks through April and May, grass from the meadows peaks through June and July, and mugwort extends into September throughout this large northern Bronx 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.
