Local Environmental Conditions
Poggibonsi's tree pollen is dominated by plane and pine, a pattern typical of Toscana and reinforced by its position on the Elsa river plain in Tuscany; grass and late-season herbs adds further exposure from nearby farmland through the warmer months. Parks and leafier streets tend to register higher counts than the built-up core.
Poggibonsi typically sees eucalyptus and cypress arrive first, followed by a plane and pine peak that defines the heart of the season, with grass and late-season herbs extending things further; January through August in total. a typically dry summer means late-season exposure stays low, something the Toscana climate here reinforces.

How often is the Poggibonsi pollen forecast updated?

Does pollen in Poggibonsi 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 Poggibonsi 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 Poggibonsi, 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. |
