Local Environmental Conditions
This area, not far from here, has the riverbank shelters hazel and willow, two trees whose pollen travels readily on the breeze. Located a short distance from here, this area has a canopy of oak and birch, birch chief among them for allergenic potency here. Maintained parkland where turf grass and ornamental species add to the grass and ragweed mix; this sits within the local area.
Near the bank, hazel and willow lead the seasonal calendar, getting an early start, typically cresting between February and March. The area's oak and birch trees pollinate through mid-to-late spring, cresting around April and May in the year's sharpest tree-pollen spike. Grass pollen builds through late spring and peaks in June, and ragweed later takes the lead 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. |
