Local Environmental Conditions
Bragança Paulista climbs into the São Paulo Serra da Mantiqueira highlands, where Araucaria pine, eucalyptus, and native Atlantic Forest species are the main pollen sources on this elevated highland plateau. The subtropical highland climate produces a well-defined pollen season, while the mountain setting creates locally variable pollen conditions and the wet summer months bring frequent rainfall interruptions throughout this São Paulo highland municipality.
Bragança Paulista sees its clearest pollen peak during the dry season, when Araucaria pine and native Atlantic Forest species pollen disperses most freely; the following wet season keeps counts down for the rest of the year.

Does pollen in Bragança Paulista 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 Bragança Paulista 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 Bragança Paulista, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
