Local Environmental Conditions
Hazel and willow take root along the waterway, both prolific contributors to early pollen counts; this sits in the wider area. Here, close by, the park's turf and planted trees form a small but steady source of grass and ragweed pollen. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
Along the waterway, hazel and willow release pollen first, arriving ahead of the rest of the season, cresting around late winter. Moving into early summer, grass pollen climbs to its seasonal high in June, handing off to ragweed, which peaks from mid-August through October. Exact peak dates shift by a few weeks year to year depending on temperature and rainfall.

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. |
