Local Environmental Conditions
West New York's Hudson County New Jersey Hudson River waterfront setting features oak, maple, and sweetgum as the main tree pollen sources, with exposure varying between the limited Palisades ridge residential areas and the more built-up waterfront commercial corridors along Bergenline Avenue. The dramatic Palisades ridge creates a distinct topographic pollen gradient between the ridge residential areas above and the Hudson waterfront commercial areas below, while the urban setting means most pollen is carried in from surrounding greener areas.
West New York's Hudson County New Jersey waterfront 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 Hudson River waterfront setting means much pollen is largely carried in from surrounding greener areas under prevailing westerly winds.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in West 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 West 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.

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. |
