Local Environmental Conditions
Surrounded by Sicilia countryside and sitting on the slopes of Monte Bonifato in western Sicily, Alcamo sees plane and olive as the leading tree pollen source, with grass and late-season herbs building steadily as the season advances. The contrast between green space and dense streets shapes how residents experience the season differently across town.
plane and hazel marks the opening of Alcamo's season, plane and olive follows as the main spring driver, and grass and late-season herbs keeps levels up into summer across the January-to-August window. hot, dry summer conditions cut the pollen season short here. The surrounding Sicilia landscape, on the slopes of Monte Bonifato in western Sicily, plays its own part in how the season unfolds locally.

When is pollen season in Alcamo?
How often is the Alcamo pollen forecast updated?
The Alcamo pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Alcamo 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 Alcamo 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 Alcamo, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
