Ouro Preto rises as the magnificent Minas Gerais highland baroque city at the heart of the historic gold and diamond district, where native cerrado trees, eucalyptus, and the dramatic Itacolomi mountain quartzite vegetation are the main pollen sources. The cerrado highland climate produces a well-defined pollen season, while the elevated mountain setting creates variable local conditions and the wet summer months bring frequent rainfall interruptions throughout this UNESCO World Heritage city.

Does pollen in Ouro Prêto 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 Ouro Prêto 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 Ouro Prêto, 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.
