Rio do Sul commands the Santa Catarina Alto Vale do Itajaí region as its main city on the Itajaí-Açu River, where native Atlantic Forest species, eucalyptus, and the river corridor vegetation are the main pollen sources. The subtropical climate produces a well-defined pollen season, while the Itajaí valley concentrates pollen under certain conditions and rainfall interruptions occur throughout the year in this important Santa Catarina highland valley city.

How often is the Rio do Sul pollen forecast updated?

Does pollen in Rio 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 Rio 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 Rio 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.
