Local Environmental Conditions
Here, not far from here, a stretch of hazel and willow lines the water, feeding some of spring's earliest pollen. Nearby, close to home here, woodland where oak stands alongside birch, the latter especially aggressive as an allergen. Maintained parkland where turf grass and ornamental species add to the grass and ragweed mix; this sits a short distance from here.
Near the bank, hazel and willow lead the seasonal calendar, peaking in late winter through March. Oak and birch nearby take over the pollen calendar through mid-spring, typically the year's sharpest tree-pollen spell, centered on April and May. Grass pollen becomes the dominant allergen through late spring, peaking in June, and ragweed later takes the lead from mid-August through October.

Does pollen in Waukesha 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 Waukesha 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 Waukesha, 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. |
