Floriano commands the Piauí central cerrado-caatinga transitional zone on the Parnaíba River as a regional hub, where native cerrado trees, caatinga scrub, and riparian gallery forest along the Parnaíba are the main pollen sources. The dry season from May to September concentrates pollen dispersal, while the wet season brings rainfall interruptions and the Parnaíba River corridor contributes locally significant riparian pollen throughout.

How often is the Floriano pollen forecast updated?
The Floriano pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Floriano 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 Floriano 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 Floriano, 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.
