Local Environmental Conditions
Palm Beach Gardens's Palm Beach County northern coastal setting features live oak, melaleuca, and sabal palm as the main tree pollen sources, with exposure varying between the greener residential communities along the Intracoastal Waterway and the more built-up commercial corridors along PGA Boulevard. The Grassy Waters Preserve and Loxahatchee Slough corridor provide particularly significant local wetland pollen sources, while the Atlantic coastal position means sea breezes create distinct coastal-inland pollen gradients.
Palm Beach Gardens's Palm Beach County Atlantic coastal setting produces an extended subtropical pollen season opening in December with melaleuca and Australian pine before grass from surrounding Palm Beach County land peaks through February and March. Mugwort and nettle extend exposure through autumn, while the Atlantic coastal position means sea breezes can periodically disperse pollen throughout the season.

Does pollen in Palm Beach Gardens 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 Palm Beach Gardens 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 Palm Beach Gardens, 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. |
