Local Environmental Conditions
For Bayview Campground, here, in the vicinity, hazel and willow line the water's edge, releasing pollen that carries easily on the wind. Woodland where oak stands alongside birch, the latter especially aggressive as an allergen, in the surrounding area. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
At Bayview Campground, the waterside hazel and willow are consistently first to release pollen each year, usually peaking sometime between late winter and the end of March. Once hazel fades, oak and birch in the woods carry the season forward, usually peaking from April into May. Grass pollen climbs toward a June peak, followed by ragweed's own peak stretch from mid-August into October.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Bourne, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

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. |
