Local Environmental Conditions
Nearby, just over 50 meters from the neighborhood, hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen. Birch and oak share the canopy here, birch pollen in particular known to travel far on the wind; this sits reasonably near, about 300 meters out. Local readings for the surrounding area tend to follow this same general pattern.
Hazel and willow near the water open the pollen calendar early, hitting its peak before most trees have even budded, around late winter into March. Oak and birch in the nearby woodland follow in mid-to-late spring, typically landing in April and May. Grass pollen takes over next, building to a peak around June, and ragweed later takes the lead from mid-August through October.

Does pollen in Wapakoneta 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 Wapakoneta 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 Wapakoneta, 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. |
