Local Environmental Conditions
Tianguá rises in the Ceará northwestern highland serra as a cool elevated agricultural municipality, where native caatinga scrub, Atlantic Forest remnants on the serra slopes, and introduced agricultural trees are the main pollen sources. The dry tropical climate concentrates pollen production during the dry season, while the elevated serra setting creates more variable local conditions and the wet season brings rainfall interruptions throughout this Ceará northwestern serra municipality.
Tianguá sees its clearest pollen peak during the dry season, when native caatinga scrub and Atlantic Forest remnants on the serra slopes pollen disperses most freely; the following wet season keeps counts down for the rest of the year.

How often is the Tianguá pollen forecast updated?

Does pollen in Tianguá 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 Tianguá 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 Tianguá, 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. |
