When is pollen season in Santo André?

The tropical highland climate means frequent rainfall during the wet summer suppresses dispersal, while the dry season concentrates pollen production across the greater ABC region of the São Paulo metropolitan area.
How often is the Santo André pollen forecast updated?

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

Does pollen in Santo André 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 Santo André 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 Santo André, 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.
