Local Environmental Conditions
Located hardly 50 meters distant, this area has moisture-loving hazel and willow dominate the bank, both quick to release pollen on the wind. Well-kept lawns and ornamental trees in this park add their share of grass and ragweed pollen, just 50m from here. Nearby weather stations report comparable trends across the broader stretch of the county.
The bank's hazel and willow kick off the pollen season ahead of the rest, getting an early start, typically cresting between February and March. Moving into early summer, grass pollen climbs to its seasonal high in June, and ragweed later takes the lead from mid-August through October. This general pattern holds fairly steady across the surrounding county from year to year.

Are pollen levels in Orion Charter 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 Orion Charter 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 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. |
