Balsas anchors the southern Maranhão cerrado-caatinga transitional zone as an expanding agricultural frontier, where native cerrado trees, babaçu palm, and soybean farmland are the main pollen sources. The dry season from May to September concentrates pollen dispersal, while the wet season from October to April brings frequent rainfall interruptions and the flat cerrado landscape allows pollen to disperse widely throughout.

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