São José extends along the Santa Catarina coast south of Florianópolis as part of the island capital's mainland metropolitan area, where native Atlantic Forest remnants, restinga coastal scrub, and introduced urban trees are the main pollen sources. The subtropical climate produces a well-defined pollen season, while the Atlantic Ocean proximity means onshore breezes can periodically disperse pollen and rainfall interruptions occur throughout the year throughout.

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