Local Environmental Conditions
Mazara del Vallo's western Sicilian wine country setting and the Mazaro River corridor olive and vine provide most of the tree pollen, and grass from Sicilia farmland contributes over the spring weeks. The Mediterranean summer that follows keeps pollen in check for the rest of the calendar year.
Mazara del Vallo's clearest pollen exposure comes from olive and vine in late winter into spring, with grass extending it briefly before the Mediterranean summer heat and drought suppress vegetation; the window runs January to June. Mugwort can extend the season briefly into early autumn in some years.

Are pollen levels in Mazara del Vallo 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 Mazara del Vallo, 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. |
