Local Environmental Conditions
Brunswick's coastal Georgia Golden Isles setting features live oak, longleaf pine, and Spanish moss-draped oak as the main tree pollen sources, with exposure varying between the wooded Golden Isles barrier island residential areas and the more built-up port and commercial corridors on the mainland. The Brunswick River and tidal marsh system create distinct coastal-mainland pollen gradients throughout the season.
Brunswick's coastal Georgia setting produces a season opening in late January with pine and oak before grass from surrounding coastal Georgia farmland peaks through April and May. Mugwort and nettle extend exposure into September, while the Atlantic coastal position means onshore sea breezes can periodically disperse pollen and the warm Southeast climate advances the season throughout.

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