Local Environmental Conditions
This area, in the vicinity, has the riverbank shelters hazel and willow, two trees whose pollen travels readily on the breeze. Oak and birch dominating the treeline, both heavy contributors to the spring pollen load, just outside the immediate area. Local microclimate and soil conditions can push these figures slightly higher or lower.
The water-adjacent hazel and willow are early risers, 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, typically the year's sharpest tree-pollen spell, centered on April and May. Late spring sees grass pollen build steadily toward a peak in June, with ragweed climbing to its own high point from mid-August through 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. |
