Local Environmental Conditions
Delray Beach's Palm Beach County Atlantic coastal setting features melaleuca, live oak, and Australian pine as the main tree pollen sources alongside subtropical vegetation. Exposure varies between the greener western residential areas and the more built-up Atlantic Avenue commercial and beachfront areas, while the Atlantic Intracoastal Waterway creates a distinct inland-coastal pollen gradient and sea breezes can periodically suppress beachfront pollen dispersal throughout.
Delray Beach's South Florida 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 and the warm climate supports near year-round production.

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