Vilhena lies in the southern Rondônia highlands on the Mato Grosso border as an agricultural gateway, where native cerrado trees, soybean farmland, and eucalyptus are the main pollen sources on this elevated Parecis plateau. The cerrado dry season from May to September concentrates pollen dispersal, while the wet season brings frequent rainfall interruptions and the flat plateau landscape allows pollen to disperse widely throughout.

How often is the Vilhena pollen forecast updated?

Does pollen in Vilhena 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 Vilhena 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 Vilhena, 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.
