Local Environmental Conditions
Viçosa do Ceará rises in the Ceará northwestern Serra de Ibiapaba highland escarpment as a cool elevated municipality, where native cerrado trees, Atlantic Forest remnants on the serra slopes, and coffee plantation vegetation are the main pollen sources. The elevated serra setting creates more variable local conditions than the surrounding sertão, while the wet season from March to July provides the most frequent rainfall interruptions throughout this Ceará highland municipality.
Viçosa do Ceará produces pollen year-round given its equatorial setting, with native cerrado trees and Atlantic Forest remnants on the serra slopes pollen present throughout; the wet season from March to July brings the most frequent rainfall interruptions to an otherwise steady pollen presence.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Viçosa do Ceará 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 Viçosa do Ceará, 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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
