Local Environmental Conditions
This area, in the wider area, has forest where oak and birch make up much of the canopy, driving spring pollen counts. A nearby park's turf and ornamental trees layer grass and ragweed pollen onto the seasonal mix; this sits within the neighborhood. The broader area tends to mirror this pattern, with only minor local variation.
Oak and birch in the woodland come next, through the heart of spring, peaking in the heart of spring, generally April into May. Late spring sees grass pollen build steadily toward a peak in June, before ragweed takes over as the dominant allergen from mid-August through October. Exact peak dates shift by a few weeks year to year depending on temperature and rainfall.

How often is the Westfield pollen forecast updated?

Does pollen in Westfield 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 Westfield 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 Westfield, 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 exposure is expected to be minimal. |
| 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. |
