Local Environmental Conditions
The center of Siracusa is surrounded mainly by built-up land, which covers around 62% of the nearby area, with a good deal of open water. With the Anapo River nearby, riverside vegetation along its banks contributes to the local mix. Olive and ash are among the allergenic trees nearby. Beyond the trees, grasses matter a great deal, and plantain is the main weed source.
Tree pollen peaks in late spring, when the weather warms to around 20°C and olive and ash are in full flower. Grasses take over in late spring and keep pollen in the air into mid-fall. Plantain flowers through much of the warmer half of the year. Rain is heaviest in spring, often giving short breaks from high pollen levels.

Does pollen in Siracusa 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 Siracusa 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 Siracusa, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
