Local Environmental Conditions
Located not far from here, this area has water here is bordered by hazel and willow, both notable sources of wind-borne pollen. Located close to this spot, this area has tree cover made up mostly of oak and birch, both significant spring allergen sources. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
Hazel and willow near the water open the pollen calendar early, hitting its peak before most trees have even budded, around late winter into March. Once hazel fades, oak and birch in the woods carry the season forward, climbing steadily through spring to a peak in April or May. Grass pollen counts rise through late spring, reaching their peak around June, before ragweed takes over as the dominant allergen from mid-August through October.

| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
