Local Environmental Conditions
Piripiri rises in the northern Piauí cerrado-caatinga transitional zone near the Serra de Ibiapaba escarpment, where native cerrado trees, caatinga scrub, and the elevated Serra vegetation above are the main pollen sources. The dry season from May to September concentrates pollen dispersal, while the wet season brings rainfall interruptions and the Serra escarpment creates locally different highland conditions throughout this northern Piauí municipality.
Piripiri's pollen season concentrates during the dry period from May to September, when caatinga scrub and the elevated Serra vegetation above pollen disperses most readily; rainfall returns for the rest of the year and interrupts pollen counts.

How often is the Piripiri pollen forecast updated?
The Piripiri pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Piripiri 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 Piripiri 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 Piripiri, 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. |
