Local Environmental Conditions
Hazel and willow line the water's edge, releasing pollen that carries easily on the wind; this sits right at hand, some 100m away. This area, conveniently close, some 400-500 meters off, has this patch of forest is largely oak and birch, a pairing known for heavy spring pollen output. Local microclimate and soil conditions can push these figures slightly higher or lower.
Water-edge hazel and willow are usually the first allergenic trees active here, climbing steadily from late winter into March. The area's oak and birch trees pollinate through mid-to-late spring, generally peaking somewhere between April and May. Grass pollen climbs toward a June peak, followed by ragweed's own peak stretch from mid-August into October.

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

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. |
