São Paulo's green corridors, including Ibirapuera Park and the Pinheiros River valley, feature eucalyptus, pine, and native Atlantic Forest species as the main tree pollen sources, with exposure varying between these greener areas and the densely built metropolitan centre. Surrounding Cerrado woodland and farmland contribute substantial grass and tree pollen, with the dry season from May to September concentrating pollen dispersal when rainfall is least frequent.

When is pollen season in São Paulo?
São Paulo's pollen season is most pronounced during the dry season from May to September, when tree pollen from eucalyptus, pine, and native Cerrado and Atlantic Forest species peaks alongside grass from urban green spaces. The wet summer months bring frequent rainfall that suppresses dispersal, while the tropical highland climate means the season is less extreme than in lower-altitude Brazilian cities.
How often is the São Paulo pollen forecast updated?

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

Does pollen in São Paulo 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 São Paulo 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 São Paulo, 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.
