Cachoeiras de Macacu rises in the Rio de Janeiro Serra Fluminense foothills as an important agricultural and conservation municipality, where native Atlantic Forest remnants, eucalyptus, and the Macacu River corridor vegetation are the main pollen sources. The very wet Atlantic Forest coastal climate provides very frequent rainfall interruptions, while the tropical climate supports year-round pollen production and the enclosed valley concentrates pollen under calm conditions throughout.

Are pollen levels in Cachoeiras de Macacu 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 Cachoeiras de Macacu, 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.
