Across Ahlen, oak, hornbeam, and birch form the backbone of local tree pollen, with parks and gardens more exposed than the town centre. Additional tree and grass pollen comes from Westphalian farmland and isolated copses surrounding the town, while the flat plain lets pollen disperse readily under prevailing westerly winds.

How often is the Ahlen pollen forecast updated?
The Ahlen pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Ahlen 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 Ahlen 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 Ahlen, 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.
