Local Environmental Conditions
Bento Gonçalves rises in the Rio Grande do Sul Serra Gaúcha wine country as Brazil's wine capital, where grapevine, Araucaria pine, and native Atlantic Forest species are the main pollen sources in this Italian-heritage highland setting. The subtropical highland climate produces a well-defined pollen season, while the vine pollen contributes a distinctive local source during spring and rainfall interruptions occur throughout the year throughout.
Bento Gonçalves's pollen season follows the region's typical pattern, led by grapevine and native Atlantic Forest species pollen, with exposure varying across the year according to local seasonal rainfall and temperature patterns.

Does pollen in Bento Gonçalves 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 Bento Gonçalves 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 Bento Gonçalves, 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. |
