Local Environmental Conditions
Cuiabá's parks feature native Cerrado species including ipê and angico as the main tree pollen sources alongside introduced grass from urban green spaces, with exposure varying between these areas and the more built-up city centre. Surrounding Cerrado savanna and the Pantanal wetland fringe contribute substantial grass and tree pollen, with the dry season from May to September concentrating pollen dispersal.
Cuiabá's pollen season is most pronounced during the dry season from May to September, when native Cerrado species including ipê and angico release pollen alongside grass from urban green spaces. The wet season from October to April brings very frequent and intense rainfall that suppresses dispersal, while the long dry season concentrates pollen production across the surrounding Cerrado savanna and the Pantanal wetland fringe.

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