Local Environmental Conditions
Open water makes up around 47% of the area near the heart of Mackinaw City, with a good deal of built-up land and some woodland. Maple is among the allergenic trees nearby. Grass pollen is a substantial part of the local mix as well. Local vegetation is sparse, so most pollen arrives on the wind from surrounding land.
Tree pollen peaks in late spring, when the weather warms to around 10°C and maple is in full flower. Grasses take over in midsummer, with temperatures around 20°C, and their pollen lingers into early fall. Weeds on open ground add a smaller late peak from early summer into early fall. Warm, damp weather from midsummer into early fall also raises mold spore levels.

Does pollen in Mackinaw City 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 Mackinaw City 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 Mackinaw City, 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. |
