Angra dos Reis spreads along the Rio de Janeiro Costa Verde Atlantic Forest coast among hundreds of islands, where native Atlantic Forest trees, restinga coastal scrub, and mangrove vegetation are the main pollen sources around this spectacular island-studded bay. The tropical climate supports year-round pollen production, while the very wet Atlantic Forest coastal climate provides very frequent rainfall interruptions throughout.

Does pollen in Angra dos Reis 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 Angra dos Reis 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 Angra dos Reis, 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.
