Local Environmental Conditions
Nearby, close to home here, along the damp banks, hazel and willow release some of the year's first tree pollen. Green space with maintained lawn and planted trees, both contributing to grass and ragweed counts; this sits just outside the immediate area. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
Along the waterway, hazel and willow release pollen first, starting well before the main spring rush, topping out around March. Late spring sees grass pollen build steadily toward a peak in June, handing off to ragweed, which peaks from mid-August through October. Regional pollen monitoring generally reflects this same pattern across nearby areas.

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. |
