Santa Rosa commands the Rio Grande do Sul northwestern highlands near the Argentine border, where native Araucaria forest remnants, eucalyptus, and soybean farmland are the main pollen sources. The subtropical highland climate produces a well-defined pollen season, while the elevated plateau setting creates a more defined seasonal progression and rainfall interruptions occur throughout the year throughout this important Rio Grande do Sul western highland agribusiness city.

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