Local Environmental Conditions
Given its setting — ancient earthwork mounds along the Ocmulgee River — Ocmulgee Mounds National Historical Park's pollen exposure lines up with the broader Macon pattern rather than diverging from it. As with most sublevel sites, local landscaping can shift counts slightly from the citywide average.
As a landmark within Macon, Ocmulgee Mounds National Historical Park follows the same seasonal pollen curve, opening with cedar and elm from February with oak taking the lead through March and April. Grass follows, peaking through April and May, while mugwort and nettle extend exposure into September. Warm, humid conditions favor an early, intense tree pollen season across the region, consistent with the wider Macon area.

Does pollen in Macon 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 Macon 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 Macon, 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. |
