Belo Horizonte's urban green spaces, including Parque Municipal and the Arrudas River corridor, feature eucalyptus, pine, and native Cerrado species as the main tree pollen sources, with exposure varying between these greener areas and the more built-up city centre. Surrounding Minas Gerais highland woodland and farmland contribute substantial tree and grass pollen, with the dry season from May to September concentrating pollen dispersal.

When is pollen season in Belo Horizonte?
Belo Horizonte's pollen season is most pronounced during the dry season from May to September, when eucalyptus, pine, and native Cerrado species release pollen and grass exposure increases across the city. The wet summer months from November to March bring frequent rainfall that suppresses dispersal, while the tropical highland setting means the season is more defined than in lower-altitude Brazilian cities closer to the equator.
How often is the Belo Horizonte pollen forecast updated?

The Belo Horizonte pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Belo Horizonte 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 Belo Horizonte 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 Belo Horizonte, 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.
