Local Environmental Conditions
São Gonçalo do Amarante lines the Rio Grande do Norte coast west of Natal near the Augusto Severo international airport, where native caatinga scrub, restinga coastal scrub, and introduced urban trees are the main pollen sources. The tropical climate supports year-round pollen production, while the wet season from February to July provides the most frequent rainfall interruptions and coastal onshore breezes can periodically disperse pollen throughout.

A good pollen forecast therefore depends on accurately representing local vegetation.

Are pollen levels in São Gonçalo do Amarante 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 São Gonçalo do Amarante, 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. |
