Local Environmental Conditions
Lauro de Freitas lines the Bahia Atlantic coast north of Salvador as part of the Bahia metropolitan region, where native Atlantic Forest remnants, restinga coastal scrub, and introduced urban trees are the main pollen sources. The tropical climate supports year-round pollen production, while the wet season from April to August provides the most frequent rainfall interruptions and coastal onshore Atlantic breezes can periodically disperse pollen throughout.
Lauro de Freitas produces pollen year-round given its equatorial setting, with native Atlantic Forest remnants and restinga coastal scrub pollen present throughout; the wet season from April to August brings the most frequent rainfall interruptions to an otherwise steady pollen presence.

How often is the Lauro de Freitas pollen forecast updated?

Does pollen in Lauro de Freitas 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 Lauro de Freitas 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 Lauro de Freitas, 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. |
