Valença in Bahia occupies the southern Bahia Atlantic Forest coast as a historic colonial port, where native Atlantic Forest remnants, restinga coastal scrub, and mangrove vegetation along the Una River are the main pollen sources. The tropical climate supports year-round pollen production, while the very wet coastal Atlantic Forest climate provides very frequent rainfall interruptions throughout this Bahia southern coast municipality.

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