Local Environmental Conditions
Greywalls at Marquette Golf Club's Upper Peninsula Michigan Lake Superior setting features paper birch, balsam fir, and native grasses as the main pollen sources across the dramatic rocky clifftop course, with exposure varying between the exposed Lake Superior-facing holes and the more sheltered forested sections. The Lake Superior position means onshore winds can frequently disperse pollen, while the subarctic Upper Peninsula climate means a more compressed but intense season with birch peaking strongly through May.
At Greywalls at Marquette Golf Club – Greywalls Course, a golf course in Marquette, the pollen season opens with maple and elm from March with oak joining in and continuing through April. Grass pollen then peaks through May and June, and a late-summer ragweed peak runs into September. Warm, humid summers in this part of the Midwest favor a pronounced late-season ragweed peak, a defining feature of the local season.

Does pollen in Marquette 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 Marquette 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 Marquette, 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. |
