Local Environmental Conditions
Santo Amaro rises in the Bahia Recôncavo as a historic colonial sugar city, where native Atlantic Forest remnants, sugarcane plantation vegetation, and eucalyptus are the main pollen sources near the Todos os Santos Bay watershed. The tropical climate supports year-round pollen production, while the wet season from April to August provides the most frequent rainfall interruptions throughout this historic Bahia Recôncavo colonial municipality.
Santo Amaro's tropical climate keeps native Atlantic Forest remnants and eucalyptus pollen in the air year-round, with the clearest breaks coming during the wet season from April to August when rainfall is most frequent.

Does pollen in Santo Amaro 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 Santo Amaro 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 Santo Amaro, 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. |
