Local Environmental Conditions
This area, within the local area, has the nearest stream or river hosts hazel and willow, two of the most allergenic early-season trees. Year-to-year swings in rainfall and wind can shift this picture somewhat either way. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall.
The water-adjacent hazel and willow are early risers, usually peaking sometime between late winter and the end of March. Grass pollen counts rise through late spring, reaching their peak around June, and then ragweed picks up the slack, running from mid-August through October. Year-to-year timing varies a little, though the general sequence stays fairly consistent here.

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. |
