Local Environmental Conditions
Maceió's coastal urban vegetation features coconut palm, mango, and native Atlantic Forest species as the main tree pollen sources, with exposure varying between the city's green spaces and the more built-up coastal and inland areas. Surrounding coastal restinga and Atlantic Forest fragments contribute additional pollen, while onshore trade winds can periodically disperse urban pollen across the coastal plain throughout the year.
Maceió's pollen season runs largely year-round in the tropical coastal climate, with grass and tree pollen exposure highest during the drier months from September to February. The wet season from April to August brings the most frequent rainfall interruptions, while consistent onshore trade winds disperse pollen across the coastal plain throughout the year.

When is pollen season in Maceió?
How often is the Maceió pollen forecast updated?
The Maceió pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Maceió 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 Maceió 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 Maceió, 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. |
