Ourinhos lies in the southwestern São Paulo interior on the Paranapanema River as a regional railway hub, where eucalyptus, sugarcane crop vegetation, and native cerrado remnants are the main pollen sources. The tropical highland climate produces a more defined pollen season, with the dry season from May to September concentrating pollen dispersal and the wet season bringing frequent rainfall interruptions throughout.

How often is the Ourinhos pollen forecast updated?

Does pollen in Ourinhos 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 Ourinhos 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 Ourinhos, 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.
