Local Environmental Conditions
Hoover High School's Football Field sits in the Hoover suburban landscape of Jefferson County, Alabama, with oak, pine, and sweet gum as the main surrounding tree pollen sources. Surrounding Alabama woodland and farmland contribute substantial tree and grass pollen, while the humid subtropical climate supports an extended pollen season and the Red Mountain ridge channels airflows locally throughout this Birmingham suburban school.
Pollen season at Hoover High School's Football Field follows Hoover's regional pattern, opening with cedar and elm from February with oak taking the lead through March and April. Grass pollen rises through April and May, and mugwort and nettle extend exposure into September. Warm, humid conditions favor an early, intense tree pollen season across the region.

Does pollen in Hoover 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 Hoover 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 Hoover, 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. |
