Santos occupies the Santos Bay island opposite the Serra do Mar escarpment, where restinga coastal vegetation, mangrove, and introduced urban trees are the main pollen sources at this major port. The very wet Serra do Mar coastal climate provides very frequent rainfall interruptions, while the tropical climate supports year-round pollen production and the Atlantic Ocean position means onshore breezes frequently disperse pollen throughout this São Paulo coastal port city.

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