Fort Myers' subtropical setting on the Gulf Coast produces an extended pollen season, with oak, pine, and palm contributing from January through spring. Grass pollen peaks through March and April, with a secondary peak after summer rains. The flat, low-lying Lee County landscape and surrounding wetlands contribute substantial grass and reed pollen, while the Gulf Coast position means onshore breezes can periodically disperse urban pollen.

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.

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 Fort Myers, 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.
