Local Environmental Conditions
Nearby, just over 50 meters from the neighborhood, along the damp banks, hazel and willow release some of the year's first tree pollen. Oak and birch trees, with birch pollen especially potent during its brief spring window; this sits practically next door, 100 meters off. Nearby, positioned about 200-300m from the neighborhood, the park's turf and planted trees form a small but steady source of grass and ragweed pollen.
Water-edge hazel and willow are usually the first allergenic trees active here, leading off the pollen calendar, with a peak generally falling in late winter. The area's oak and birch trees pollinate through mid-to-late spring, usually peaking from April into May. Through late spring, grass pollen climbs steadily toward its June peak, before ragweed takes over as the dominant allergen from mid-August through October.

Does pollen in Kelleys Island come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. 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 Kelleys Island 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 Kelleys Island, 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. |
