Local Environmental Conditions
Apollo HS's Baseball Diamond is set in the Glendale suburban landscape of the San Fernando Valley in Los Angeles County, with introduced olive, eucalyptus, and California sycamore as the main surrounding pollen sources. The San Gabriel Mountains backdrop contributes chaparral and oak pollen, while the mild Southern California climate advances the season and the valley setting can concentrate pollen under calm conditions throughout.
Pollen season at Apollo HS's Baseball Diamond follows Owensboro's regional pattern, opening with cedar and elm from February before oak extends the tree season through March and April. Grass pollen then peaks through April and May, and a modest late-summer weed pollen tail continues into September. Warm, humid conditions favor an early, intense tree pollen season across the region, consistent with the wider Owensboro area.

Does pollen in Owensboro 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 Owensboro 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 Owensboro, 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. |
