Does pollen in New York come from nearby or far away?
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.
Are pollen levels in New York based on measurements or forecasts?
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.

| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
