Local Environmental Conditions
In Villefranche-sur-Saône, tree pollen mainly comes from birch and oak found in parks and along the Allier. The alpine valley pasture and orchards nearby are a major source of grass pollen later in the season, with the alpine-continental climate influencing the intensity and timing of exposure.
Villefranche-sur-Saône's pollen calendar starts in late winter, led by hazel and alder, then peaks with birch and oak across April and May, before the season closes with grass from alpine valley farmland through early summer, a pattern typical of the alpine-continental climate here.

Does pollen in Villefranche-sur-Saône 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 Villefranche-sur-Saône 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 Villefranche-sur-Saône, 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. |
