Local Environmental Conditions
This area, not far from here, has a stretch of hazel and willow lines the water, feeding some of spring's earliest pollen. A park combining lawn grass and planted trees, both minor but real contributors to pollen here, close by. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall.
Water-edge hazel and willow are usually the first allergenic trees active here, building through the tail end of winter into March. Grass pollen counts rise through late spring, reaching their peak around 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.

How often is the Waunakee pollen forecast updated?

Does pollen in Waunakee 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 Waunakee 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 Waunakee, 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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
