Dortmund's parks and green spaces feature linden, oak, and ash as the main tree pollen sources, with exposure varying between these areas and the more built-up centre. Ruhr-area farmland together with urban park greenery nearby boosts local tree and grass pollen levels, while reclaimed sites add patchy but growing local vegetation.

How often is the Dortmund pollen forecast updated?

Does pollen in Dortmund 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 Dortmund 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 Dortmund, 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.
