Local Environmental Conditions
Old Town Club's North Carolina Winston-Salem setting features oak, loblolly pine, and sweetgum as the main pollen sources across the parkland course, with exposure varying between the wooded fairway sections and the more open areas. Surrounding North Carolina Piedmont woodland and farmland contribute substantial tree and grass pollen, while the warm Southeast climate advances the season and mugwort extends exposure into September throughout this Piedmont course.
Old Town Club – Championship Course tracks Winston-Salem's broader pollen pattern, with cedar and elm appearing from February with oak following close behind through March and April. A grass pollen peak follows through April and May; mugwort and nettle extend exposure into September. Mild winters across the Southeast push the pollen calendar earlier than in most of the country, a defining feature of the local season.

Does pollen in Winston-Salem 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.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Winston-Salem 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 Winston-Salem, 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. |
