São Francisco do Sul occupies a historic island on the Santa Catarina northern coast as one of Brazil's oldest colonial settlements and an important port, where native Atlantic Forest remnants, restinga coastal scrub, and mangrove vegetation are the main pollen sources on this bay island. The subtropical climate produces a well-defined pollen season, while the Atlantic Ocean position means onshore breezes can periodically disperse pollen and rainfall interruptions occur throughout the year throughout.

How often is the São Francisco do Sul pollen forecast updated?

Does pollen in São Francisco do Sul 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 Francisco do Sul 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 Francisco do Sul, 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.
