Local Environmental Conditions
The area around the center of Barra Mansa is mostly built-up land, with a good deal of woodland. Close to the Sul River, riverside vegetation adds to local tree pollen. Locally, the woodland makes trees an important source; planted trees and mown lawns are the main sources in the built-up parts.
Tree pollen comes first, peaking in early spring. Grasses take over in mid-spring and keep pollen in the air into mid-fall. A smaller weed peak follows from early summer into early fall. In warm, humid weather from early summer into late fall, mold spores add to the mix, especially after rain.

Does pollen in Barra Mansa 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 Barra Mansa 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 Barra Mansa, 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.

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. |
