Local Environmental Conditions
Savannah's parks, including Forsyth Park and the Savannah River corridor, feature oak, pine, and magnolia as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Georgia coastal plain woodland and wetlands contribute substantial tree and grass pollen, while the coastal position means onshore Atlantic breezes can periodically disperse urban pollen.
Savannah's pollen season opens with oak and pine from late January, producing intense tree pollen through February and March. Grass pollen follows through April and May, with ragweed extending the season into October. The coastal position means onshore Atlantic breezes can periodically disperse pollen, while surrounding Georgia coastal plain woodland and wetlands contribute substantial tree and grass pollen throughout the extended season.

How often is the Savannah pollen forecast updated?
The Savannah pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Savannah 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 Savannah 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 Savannah, 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. |
