Vénissieux' riverside green spaces and the Rhône River corridor feature oak, plane, and linden as the main tree pollen sources, with exposure varying between these areas and the more built-up industrial city centre. As part of the Lyon metropolitan area, local sources dominate, while the warm Rhône plain microclimate and surrounding Rhône-Alpes farmland contribute substantial grass and tree pollen throughout the season.

How often is the Vénissieux pollen forecast updated?

Does pollen in Vénissieux 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 Vénissieux 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 Vénissieux, 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.
