Local Environmental Conditions
Pato Branco anchors the southwestern Paraná highlands near the Santa Catarina border, where Araucaria pine, eucalyptus, and native Atlantic Forest species are the main pollen sources on this elevated Terceiro Planalto. The subtropical highland climate produces a well-defined pollen season, while the Araucaria pine contributes a distinctive local pollen source and the wet summer months bring frequent rainfall interruptions throughout this southwestern Paraná highland municipality.
Pato Branco's pollen season concentrates during the dry season, when eucalyptus and native Atlantic Forest species pollen disperses most readily across the area; the wet season brings frequent rainfall that interrupts counts for the rest of the year.

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