Passos occupies the southern Minas Gerais cerrado as a coffee and agricultural hub on the Verde River, where native cerrado trees, eucalyptus, and coffee plantation vegetation are the main pollen sources. The cerrado climate produces a well-defined pollen season, with the dry season from May to September concentrating pollen dispersal and the wet summer months bringing frequent rainfall interruptions throughout.

How often is the Passos pollen forecast updated?

Does pollen in Passos 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 Passos 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 Passos, 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.
