Registro rises in the São Paulo Vale do Ribeira as a Japanese-heritage municipality and tea growing centre, where native Atlantic Forest remnants, tea plantation vegetation, and eucalyptus are the main pollen sources alongside the Ribeira do Iguape River. The subtropical highland climate produces a more defined pollen season, while the very wet Vale do Ribeira Atlantic Forest climate provides very frequent rainfall interruptions throughout this important São Paulo conservation and agricultural corridor municipality.

How often is the Registro pollen forecast updated?
The Registro pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Registro 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 Registro 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 Registro, 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.
