Local Environmental Conditions
Bergen Catholic HS's Football Field sits in the Oradell suburban landscape of Bergen County, New Jersey, with oak, maple, and birch as the main surrounding tree pollen sources. Surrounding New Jersey suburban woodland and farmland contribute substantial tree and grass pollen, while the moderate mid-Atlantic climate advances the season and mugwort extends exposure into September throughout this Bergen County suburban Catholic school.
Bergen Catholic HS's Football Field follows Oradell's established pollen calendar, beginning with cedar and elm from late February before oak takes over and peaks through April. Grass pollen then peaks through May and June, and ragweed and mugwort extend the weed season into September. The mild mid-Atlantic climate advances the season compared to more northern East Coast cities, a pattern felt across this part of Oradell.

Does pollen in Oradell 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 Oradell 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 Oradell, 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. |
