Local Environmental Conditions
Red mangrove and black mangrove crowd the water's edge, typical of this coast's tidal waterways, within the neighborhood's edge. Slash pine and cabbage palm dominating the treeline, both typical of this area's woodland, within the local area. The park's turf and planted trees form a small but steady source of grass and ragweed pollen, a short distance from here.
Here, average temperatures run from roughly 21°C in January to 29°C in August, and the bulk of this area's 1464 mm annual rainfall comes during the warmer months, around August. Expect pollen activity to start building from around February, tracking the rise in temperature out of the January low.

Does pollen in Royal Palm 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 Royal Palm 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 Royal Palm 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. |
