Local Environmental Conditions
Granja commands the far western Ceará coast near the Piauí border as a carnauba wax and coastal municipality, where coconut palm, carnauba wax palm, and coastal dune vegetation are the main pollen sources. The dry tropical climate concentrates pollen production from July to January, while consistent trade winds frequently disperse pollen and the brief wet season from February to May brings rainfall interruptions throughout.
Granja's tropical climate keeps coconut palm and coastal dune vegetation pollen in the air year-round, with the clearest breaks coming during the wet season from February to May when rainfall is most frequent.

How often is the Granja pollen forecast updated?

Does pollen in Granja 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 Granja 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 Granja, 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. |
