São Pedro da Aldeia lies on the Rio de Janeiro Região dos Lagos coastal lagoon as a popular resort, where restinga coastal scrub, introduced urban trees, and lagoon-edge vegetation are the main pollen sources. The tropical climate supports year-round pollen production, while the coastal position means onshore Atlantic breezes can periodically disperse pollen and the wet summer months bring the most frequent rainfall interruptions throughout.

Are pollen levels in São Pedro da Aldeia 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 São Pedro da Aldeia, 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.
