Local Environmental Conditions
Alagoinhas lies on the Bahia recôncavo plateau north of Salvador, where eucalyptus, native caatinga scrub, and Atlantic Forest remnants are the main pollen sources. The semi-arid transitional climate produces a more defined pollen season, with the wet season from April to August providing the most frequent rainfall interruptions throughout this northeastern Bahia plateau municipality.
In Alagoinhas, native caatinga scrub and Atlantic Forest remnants pollen disperses continuously through the year with no distinct seasonal boundary, though the wet season from April to August regularly interrupts counts with frequent rainfall.

Does pollen in Alagoinhas 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 Alagoinhas 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 Alagoinhas, 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. |
