Cholet's Parc de Moine and the Maine-et-Loire bocage farmland corridor feature oak, birch, and linden as the main tree pollen sources, with exposure varying between these green areas and the more built-up industrial city centre. Surrounding Maine-et-Loire bocage woodland contributes substantial tree pollen during spring, while surrounding farmland extends grass pollen and the Atlantic oceanic climate means frequent rainfall provides regular interruptions.

How often is the Cholet pollen forecast updated?

Does pollen in Cholet 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 Cholet 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 Cholet, 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.
