Local Environmental Conditions
The water's edge is thick with hazel and willow, whose pollen spreads readily in early spring; this sits about 300 meters off. A mix of oak and birch trees, birch in particular a notorious spring allergen source, barely 100 meters away. A park where mown turf grass and ornamental trees add grass and ragweed pollen, as close as 100m from this location.
The waterside hazel and willow are consistently first to release pollen each year, arriving ahead of the rest of the season, cresting around late winter. Oak and birch in the woods pick up where the earlier species leave off, reaching maximum intensity across the April-May window. Grass pollen takes over next, building to a peak around June, and ragweed later takes the lead from mid-August through October.

A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Canal Winchester based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Canal Winchester, 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. |
