Local Environmental Conditions
Paterson Great Falls National Historical Park is a 77-foot waterfall on the Passaic River downtown. Vegetation here reflects the wider Paterson area, with tree and grass pollen exposure following the same regional pattern as the rest of the city. Any difference from the citywide pattern here tends to be minor rather than a distinct microclimate.
Paterson Great Falls National Historical Park follows Paterson's established pollen calendar, beginning with cedar and elm from late February then oak builds through April. Grass pollen builds through May and June, and ragweed and mugwort extend the weed season into September. Relatively mild winters here bring the tree pollen season forward compared to points further north, consistent with the wider Paterson area.

Does pollen in Paterson 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 Paterson 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 Paterson, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
