São Borja commands the Rio Grande do Sul western border on the Uruguay River opposite Argentina as the birthplace of two Brazilian presidents, where native pampa grasses, eucalyptus, and riparian gallery forest along the Uruguay River are the main pollen sources. The subtropical climate produces a well-defined pollen season, while the flat Campanha landscape allows pollen to disperse widely and rainfall interruptions occur throughout the year throughout this historic Rio Grande do Sul river border city.

How often is the São Borja pollen forecast updated?

Does pollen in São Borja 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 Borja 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 Borja, 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.
