Local Environmental Conditions
This area, just around the area, has along the damp banks, hazel and willow release some of the year's first tree pollen. This area, a short distance from here, has forest where oak and birch make up much of the canopy, driving spring pollen counts. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
The bank's hazel and willow kick off the pollen season ahead of the rest, peaking in late winter through March. As spring advances, oak and birch in the nearby woodland become the dominant source, usually hitting its highest point sometime between mid-April and mid-May. Grass pollen takes over next, building to a peak around June, before ragweed's late-summer surge carries the season into October.

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. |
