Port St. Lucie's suburban setting on Florida's Treasure Coast features oak, pine, and palm as the main tree pollen sources in parks and along residential streets, with exposure varying between these green areas and the more built-up city centre. Surrounding St. Lucie County wetlands and coastal grasslands contribute grass and reed pollen, while the flat, open landscape allows pollen to disperse readily across the area.

How often is the Port St. Lucie pollen forecast updated?

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.
