Local Environmental Conditions
Page High School's Soccer Field is set in the suburban Greensboro landscape of the North Carolina Piedmont, with oak, pine, and sweet gum as the main surrounding tree pollen sources. Surrounding Piedmont woodland and farmland contribute substantial tree and grass pollen, while the humid subtropical climate supports an extended pollen season and mugwort extends exposure into September throughout this Piedmont suburban school setting.
At Page High School's Soccer Field, a soccer venue in Greensboro, the pollen season opens with cedar and elm from February before oak extends the tree season through March and April. Grass pollen builds through April and May, and a modest late-summer weed pollen tail continues into September. The warm Southeast climate advances the season compared to more northern US regions, a defining feature of the local season.

Does pollen in Greensboro 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 Greensboro 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 Greensboro, 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. |
