Local Environmental Conditions
Located a short distance from here, this area has the waterway's edge supports hazel and willow, species known for potent, wind-carried pollen. Woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen; this sits a short distance from here. Maintained parkland where turf grass and ornamental species add to the grass and ragweed mix, close to this spot.
Hazel and willow near the water open the pollen calendar early, starting well before the main spring rush, topping out around March. Once hazel fades, oak and birch in the woods carry the season forward, usually hitting its highest point sometime between mid-April and mid-May. Grass pollen rises through late spring toward a June high point, before ragweed takes over as the dominant allergen 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. |
