Local Environmental Conditions
Pacajus lies on the Ceará eastern metropolitan fringe east of Fortaleza, where native caatinga scrub, coconut palm, and introduced urban trees are the main pollen sources. The dry tropical climate concentrates pollen production from July to January, while the brief wet season from February to May provides rainfall interruptions and coastal proximity means onshore trade winds can periodically disperse pollen throughout.
Pacajus's tropical climate keeps native caatinga scrub and introduced urban trees 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 Pacajus pollen forecast updated?

Does pollen in Pacajus 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 Pacajus 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 Pacajus, 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. |
