Set on flat sugarcane-farming country on the south shore of Lake Okeechobee, Clewiston's landscape is defined by sugarcane fields alongside cabbage palm hammocks and lakeside marsh vegetation, the main contributors to seasonal pollen exposure. Wind patterns across the area help determine how far pollen travels from these source plants. Microclimates within the area can shift the timing slightly from one neighborhood to the next.

Does pollen in Clewiston 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 Clewiston 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 Clewiston, 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.
