Local Environmental Conditions
Marechal Deodoro occupies the Alagoas coastal plain near Maceió at the Mundaú-Manguaba lagoon system as the birthplace of Brazil's first republic president, where native Atlantic Forest remnants, restinga coastal scrub, and mangrove vegetation 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 the coastal position means onshore Atlantic breezes can periodically disperse pollen throughout.
Marechal Deodoro's tropical climate keeps native Atlantic Forest remnants and mangrove vegetation pollen in the air year-round, with the clearest breaks coming during the wet season from April to August when rainfall is most frequent.

How often is the Marechal Deodoro pollen forecast updated?

Does pollen in Marechal Deodoro 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 Marechal Deodoro 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 Marechal Deodoro, 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. |
