How to connect?

São Mateus lies in the northern Espírito Santo on the São Mateus River as a centre of quilombo heritage, where native Atlantic Forest remnants, eucalyptus, and the São Mateus River corridor vegetation are the main pollen sources. The tropical climate supports year-round pollen production, while the river valley concentrates pollen under calm conditions and the wet summer months bring the most frequent rainfall interruptions throughout.

How often is the São Mateus pollen forecast updated?

Does pollen in São Mateus 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 Mateus 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 Mateus, 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.
