Local Environmental Conditions
Here, within easy reach at 300-400m, oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two. The broader area tends to mirror this pattern, with only minor local variation. Seasonal timing here generally tracks the wider region, give or take a week or so.
As spring advances, oak and birch in the nearby woodland become the dominant source, cresting around April and May in the year's sharpest tree-pollen spike. Grass pollen becomes the dominant allergen through late spring, peaking in June, before ragweed's late-summer surge carries the season into October. Small variations in local weather can nudge these windows a few days in either direction.

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. |
