Local Environmental Conditions
Beechwood Commons — Here, just 147m from here, hazel and willow crowd the water's edge, both classic sources of early allergenic pollen. Located a moderate 429 meters from here, this area has woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen. Here, just over 122 meters from the neighborhood, a park combining lawn grass and planted trees, both minor but real contributors to pollen here.
Water-edge hazel and willow are usually the first allergenic trees active here, climbing steadily from late winter into March. Oak and birch in the nearby woodland follow in mid-to-late spring, usually peaking from April into May. Grass pollen builds through late spring and peaks in June, followed by ragweed's own peak stretch from mid-August into October.

How often is the Normal pollen forecast updated?
The Normal pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Normal 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 Normal 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 Normal, 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. |
