Local Environmental Conditions
Palhoça extends along the Santa Catarina coast south of Florianópolis as part of the island capital's southern metropolitan area, where native Atlantic Forest remnants, restinga coastal scrub, and the Cubatão River corridor vegetation are the main pollen sources. The subtropical climate produces a well-defined pollen season, while Atlantic Ocean proximity means onshore breezes can periodically disperse pollen and rainfall interruptions occur throughout the year throughout.
Palhoça's pollen season follows the region's typical pattern, led by native Atlantic Forest remnants and the Cubatão River corridor vegetation pollen, with exposure varying across the year according to local seasonal rainfall and temperature patterns.

How often is the Palhoça pollen forecast updated?

Does pollen in Palhoça 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 Palhoça 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 Palhoça, 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. |
