Local Environmental Conditions
This area, close to home here, has hazel and willow cluster near the water, an early and reliable source of allergenic pollen. Located in the surrounding area, this area has tree cover made up mostly of oak and birch, both significant spring allergen sources. A park whose turf grass and ornamental plantings feed local grass and ragweed pollen levels; this sits just around the area.
The water-adjacent hazel and willow are early risers, reaching its high point sometime in late winter or early spring. Once hazel fades, oak and birch in the woods carry the season forward, topping out in the April-to-May stretch. Through late spring, grass pollen climbs steadily toward its June peak, before ragweed's late-summer surge carries the season into October.

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 Peoria Heights 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 Peoria Heights, 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. |
