Local Environmental Conditions
A waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species, within the local area. Here, in the vicinity, mown grass and ornamental trees in a nearby park, adding to seasonal grass and ragweed pollen. Year-to-year swings in rainfall and wind can shift this picture somewhat either way.
The bank's hazel and willow kick off the pollen season ahead of the rest, usually the first pollen source active, peaking sometime in February or March. Grass pollen builds through late spring and peaks in June, then yields to ragweed, the dominant late-summer and fall allergen through October. Regional pollen monitoring generally reflects this same pattern across nearby areas.

Does pollen in Mount Prospect 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 Mount Prospect 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 Mount Prospect, 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. |
