Local Environmental Conditions
Stone Mountain Park is a granite monadnock surrounded by oak-pine forest in the Georgia Piedmont. Pine pollen is intense in March and April — coating the granite dome in yellow. Oak follows through May. A major pollen producer in the metro Atlanta zone.
Stone Mountain Park follows Stone Mountain's established pollen calendar, beginning with cedar and elm from February before oak extends the tree season through March and April. Peak grass pollen arrives in April and May, and a modest late-summer weed pollen tail continues into September. Mild winters across the Southeast push the pollen calendar earlier than in most of the country, a pattern felt across this part of Stone Mountain.

How often is the Stone Mountain pollen forecast updated?

Does pollen in Stone Mountain 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 Stone Mountain 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 Stone Mountain, 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. |
