Local Environmental Conditions
Here, close to home here, hazel and willow take root along the waterway, both prolific contributors to early pollen counts. Nearby, in the vicinity, woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen. As with most local readings, actual levels can vary somewhat with short-term weather swings.
Hazel and willow near the water open the pollen calendar early, getting an early start, typically cresting between February and March. Oak and birch nearby take over the pollen calendar through mid-spring, cresting around April and May in the year's sharpest tree-pollen spike. Grass pollen counts rise through late spring, reaching their peak around June, before ragweed becomes the more dominant allergen from mid-August 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. |
