Local Environmental Conditions
Buffalo Grove HS's Football Field sits in the Buffalo Grove suburban landscape of Lake County, Illinois, with oak, maple, and elm as the main surrounding tree pollen sources. Surrounding Lake County woodland and farmland contribute substantial grass and tree pollen, while the flat Midwest landscape allows pollen to disperse widely and mugwort extends exposure into September throughout this northern Illinois suburban school setting.
Buffalo Grove HS's Football Field tracks Buffalo Grove's broader pollen pattern, with maple and elm appearing from March with oak joining in and continuing through April. Grass follows, peaking through May and June, while ragweed pollen builds steadily from August into September. The continental Midwest climate produces a well-defined spring tree peak followed by a strong late-summer ragweed season, consistent with the wider Buffalo Grove area.

Does pollen in Buffalo Grove come from nearby or far away?

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 Buffalo Grove 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 Buffalo Grove, 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. |
