How to connect?

linden, oak, and spruce supply most of the tree pollen across Radolfzell's parks and gardens, with levels varying between green space and the town centre. southwestern Baden-Württemberg farmland and lakeside forest on the town's outskirts add to local tree and grass pollen, while nearby lake waters moderate local temperatures and pollen timing.

How often is the Radolfzell pollen forecast updated?

Does pollen in Radolfzell 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 Radolfzell 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 Radolfzell, 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.
