Local Environmental Conditions
Waukesha's Pewaukee Lake and Fox River setting features oak, maple, and elm as the main tree pollen sources, with exposure varying between the greener residential areas near the numerous lakes and the more built-up commercial corridors along Highway 164. The Fox River corridor provides locally significant green space, while the numerous glacial lakes create distinct microhabitats and temperature-modifying effects that influence local pollen dispersal.
Waukesha's Milwaukee suburban setting in Wisconsin produces a season opening in late March with elm and maple before birch and oak peak through May. Grass from surrounding Wisconsin farmland peaks through June and July before mugwort and nettle extend exposure into September. The Fox River valley channels airflows, while the continental climate produces a well-defined seasonal progression throughout.

When is pollen season in Waukesha?
How often is the Waukesha pollen forecast updated?
The Waukesha pollen forecast is updated four times daily. See the timestamp below for the most recent update.
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. |
