Local Environmental Conditions
Viçosa commands the Minas Gerais Zona da Mata highlands as home of the renowned Federal University of Viçosa, where native Atlantic Forest remnants, eucalyptus, and coffee plantation vegetation are the main pollen sources. The tropical highland climate produces a more defined pollen season, while the very wet Zona da Mata climate provides frequent rainfall interruptions and the elevated setting creates variable local conditions throughout this important Minas Gerais agricultural university city.
Viçosa's pollen season follows the region's typical pattern, led by native Atlantic Forest remnants and coffee plantation vegetation pollen, with exposure varying across the year according to local seasonal rainfall and temperature patterns.

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