Local Environmental Conditions
Irvington's northeastern New Jersey urban setting features oak, maple, and sweetgum as the main tree pollen sources, with exposure varying between the limited wooded residential areas and the more built-up commercial and industrial corridors along Springfield Avenue. The Weequahic Park corridor provides the most significant local green space, while the dense urban Essex County setting means most pollen is carried in from surrounding greener suburban areas under prevailing westerly winds throughout.
Irvington's northeastern New Jersey urban setting produces a season opening in March with elm and maple before oak peaks through April and May. Grass from surrounding New York and New Jersey land peaks through June and July before mugwort and nettle extend exposure into September. The urban New York metropolitan setting means much pollen is largely carried in from surrounding greener areas under prevailing westerly winds.

Does pollen in Irvington 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 Irvington 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 Irvington, 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. |
