Local Environmental Conditions
The landscape around the heart of Princeville is mainly farmland. With the Illinois River nearby, riverside vegetation along its banks contributes to the local mix. Locally, farmland adds grass and weed pollen. Pasture and uncultivated field edges in the farmland provide room for grasses and weeds. Wind carries pollen over long distances, so the wider landscape also shapes what arrives here.
Grasses take over in late spring, with temperatures around 15°C, and their pollen lingers into early fall. Weeds on open ground add a smaller late peak from early summer into early fall. Summer is the wettest time of year, and heavy showers can bring short breaks in pollen. By late fall, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Princeville pollen forecast updated?

Does pollen in Princeville 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 Princeville 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 Princeville, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
