Local Environmental Conditions
Around Eagle Creek Golf Club, a stretch of hazel and willow lines the water, feeding some of spring's earliest pollen, in the vicinity. Nearby weather stations report comparable trends across the broader stretch of the county. Small shifts in elevation or soil type can move these figures a little either way.
At Eagle Creek Golf Club, along the waterway, hazel and willow release pollen first, getting an early start, typically cresting between February and March. Late spring sees grass pollen build steadily toward a peak in June, before ragweed takes over as the dominant allergen from mid-August through October. Local weather swings can shift these windows slightly, but the overall order tends to hold.

Does pollen in Willmar 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 Willmar 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 Willmar, 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. |
