Local Environmental Conditions
Nearby, close by, hazel and willow crowd the water's edge, both classic sources of early allergenic pollen. A park where mown turf grass and ornamental trees add grass and ragweed pollen; this sits within easy reach. Nearby weather stations report comparable trends across the broader stretch of the county. Small shifts in elevation or soil type can move these figures a little either way.
The bank's hazel and willow kick off the pollen season ahead of the rest, building through the tail end of winter into March. Grass pollen counts rise through late spring, reaching their peak around June, with ragweed climbing to its own high point from mid-August through October. The overall order of species tends to hold steady, even as exact dates shift slightly each year.

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. |
