Local Environmental Conditions
The riverbank shelters hazel and willow, two trees whose pollen travels readily on the breeze, some 400 meters out. Woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen; this sits roughly 300-400m away. Nearby, a comfortable 400-500 meters away, a park whose turf grass and ornamental plantings feed local grass and ragweed pollen levels.
Hazel and willow near the water open the pollen calendar early, leading off the pollen calendar, with a peak generally falling in late winter. Once hazel fades, oak and birch in the woods carry the season forward, peaking in the heart of spring, generally April into May. Grass pollen takes over next, building to a peak around June, before ragweed pollen takes center stage across mid-August into 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. |
