Local Environmental Conditions
Located just outside the immediate area, this area has hazel and willow cluster near the water, an early and reliable source of allergenic pollen. Neighboring areas with similar land cover tend to show a closely matching pollen mix. Year-to-year swings in rainfall and wind can shift this picture somewhat either way.
The bank's hazel and willow kick off the pollen season ahead of the rest, hitting its peak before most trees have even budded, around late winter into March. Grass pollen rises through late spring toward a June high point, with ragweed then rising to the fore 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. |
