Local Environmental Conditions
Golf Club of Georgia's setting on a wooded parkland course north of Atlanta near Alpharetta supports mature pine and oak canopy, dogwood understory, and Bermuda grass fairways as the dominant local vegetation shaping the pollen count. As with most golf courses, maintained turf areas see somewhat different exposure than the wooded rough.
Golf Club of Georgia, a golf course in Alpharetta, opens its pollen season 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 ragweed extends the weed season into September. The warm Southeast climate advances the season compared to more northern US regions, consistent with the wider Alpharetta area.

How often is the Alpharetta pollen forecast updated?

Does pollen in Alpharetta 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 Alpharetta 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 Alpharetta, 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. |
