Local Environmental Conditions
Fox River Bluffs — A stretch of hazel and willow lines the water, feeding some of spring's earliest pollen; this sits just 229m from here. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall. Local microclimate and soil conditions can push these figures slightly higher or lower.
Near the bank, hazel and willow lead the seasonal calendar, peaking in late winter through March. Grass pollen rises through late spring toward a June high point, and ragweed later takes the lead from mid-August through October. Daily pollen counts published for the wider region track this same seasonal rhythm closely.

Does pollen in East Dundee 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 East Dundee 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 East Dundee, 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. |
