Local Environmental Conditions
Poços de Caldas rises on the Minas Gerais-São Paulo highland border as a famous thermal spa resort, where native Atlantic Forest and cerrado species, eucalyptus, and coffee plantation vegetation are the main pollen sources on this volcanic plateau. The subtropical highland climate produces a well-defined pollen season, while the elevated plateau rim setting creates variable local conditions and the wet summer months bring frequent rainfall interruptions throughout this renowned Minas Gerais spa resort city.
Expect the strongest pollen exposure in Poços de Caldas during the dry season, when cerrado species and eucalyptus pollen disperses most easily, while the wet season brings the regular relief of rainfall.

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. |
