Mulhouse' Parc Salvator and the Doller and Ill river corridors feature oak, birch, and plane as the main tree pollen sources, with exposure varying between these green areas and the more built-up industrial city centre. Surrounding Alsatian vineyard farmland and the Vosges foothills contribute substantial tree and grass pollen, while the warm Alsace Rhine plain microclimate extends the pollen season compared to surrounding upland areas.

How often is the Mulhouse pollen forecast updated?

The Mulhouse pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Mulhouse 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 Mulhouse 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 Mulhouse, 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.
