Local Environmental Conditions
Open water makes up almost 50% of the area near the heart of Pôrto Seguro, with a good deal of built-up land and some mangroves. Local vegetation is sparse, so most pollen arrives on the wind from surrounding land. In the built-up parts of the area, street trees, gardens and park lawns add to the local mix.
With warm weather all year, between about 20°C and 25°C, pollen is present in most months rather than in one short season. Levels tend to be highest in drier spells, especially around September. During the rainy season, frequent heavy downpours wash much of the pollen out of the air. Mold spores join in from mid-fall into late winter, when damp, warm spells let them thrive.

Does pollen in Pôrto Seguro 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 Pôrto Seguro 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 Pôrto Seguro, 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.
