Local Environmental Conditions
Juazeiro do Norte nestles in the Cariri region of Ceará at the foot of the Chapada do Araripe, where native caatinga scrub, fruit orchards, and the elevated Chapada vegetation above are the main pollen sources. The semi-arid climate produces a compressed wet season from February to May, while the dry season concentrates pollen production and the Chapada escarpment creates locally different highland conditions throughout this important northeastern religious pilgrimage city.
In Juazeiro do Norte, fruit orchards and the elevated Chapada vegetation above pollen disperses continuously through the year with no distinct seasonal boundary, though the wet season from February to May regularly interrupts counts with frequent rainfall.

Are pollen levels in Juazeiro do Norte 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 Juazeiro do Norte, 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. |
