Local Environmental Conditions
Ribeira do Pombal lies in the Bahia northeastern sertão as a commercial hub near the São Francisco River basin, where native caatinga scrub, mandacaru cactus, and sparse drought-adapted trees are the main pollen sources. The very semi-arid climate produces an extremely compressed wet season, while the long dry season strongly concentrates pollen production and the open northeastern landscape allows very wide pollen dispersal throughout.
Ribeira do Pombal sees its clearest pollen peak during the dry season, when native caatinga scrub and mandacaru cactus pollen disperses most freely; the following wet season keeps counts down for the rest of the year.

Does pollen in Ribeira do Pombal 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 Ribeira do Pombal 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 Ribeira do Pombal, 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. |
