Local Environmental Conditions
Almost 40% of the area near the center of Napoleon Township is woodland, with a good deal of open grassland and farmland. Common allergenic trees nearby include oak and maple. Grasses are also a significant pollen source here. Field margins, fallow strips and pasture around the farmland add further grass and weed pollen.
Oak and maple lead the season in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Then come the grasses, strongest in early summer and fading by early fall. A smaller weed peak follows from early summer into early fall. Rain is heaviest in summer, often giving short breaks from high pollen levels.

How often is the Napoleon Township pollen forecast updated?

Does pollen in Napoleon Township 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 Napoleon Township 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 Napoleon Township, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
