Local Environmental Conditions
Moisture-loving hazel and willow dominate the bank, both quick to release pollen on the wind, close to this spot. The tree cover here leans heavily on oak and birch, both key drivers of spring pollen, not far from here. Ground-level conditions like local landscaping can nudge these figures slightly either way.
Near the bank, hazel and willow lead the seasonal calendar, topping out well before most other trees start releasing pollen, around February and March. Oak and birch in the nearby woodland follow in mid-to-late spring, generally peaking somewhere between April and May. Grass pollen builds through late spring and peaks in June, then yields to ragweed, the dominant late-summer and fall allergen through October.

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 Town of Chester, 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. |
