Local Environmental Conditions
Dawn On The Lake — Located close enough to matter, at 81m, this area has a waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species. Tree cover made up mostly of oak and birch, both significant spring allergen sources, just 55m from here. Ground-level conditions like local landscaping can nudge these figures slightly either way.
Hazel and willow near the water open the pollen calendar early, topping out well before most other trees start releasing pollen, around February and March. Oak and birch in the woodland come next, through the heart of spring, usually peaking from April into May. Grass pollen takes over next, building to a peak around June, before ragweed takes over as the dominant allergen from mid-August through October.

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 Heights 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 Heights, 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. |
