Local Environmental Conditions
Given its setting — a coastal wetland and pine flatwoods preserve — Savannas Preserve State Park's pollen exposure lines up with the broader Port St. Lucie pattern rather than diverging from it. Visitors should expect roughly the same seasonal pattern as elsewhere in the city, with only minor local variation.
Port St. Lucie's regional pollen pattern holds at Savannas Preserve State Park, with oak and pine first appearing in January before cypress takes over and peaks through February. There is no single sharp grass peak here; grass pollen instead runs at elevated levels for much of the year, and warm, humid conditions keep mold spore counts elevated year-round. Year-round warmth keeps some pollen and mold present in almost every month, consistent with the wider Port St. Lucie area.

Does pollen in Port St. Lucie 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 Port St. Lucie 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 Port St. Lucie, 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. |
