Bielefeld's pollen season unfolds from January through August, led off by early alder and hazel in January with birch climbing through April into May. Summer grass pollen follows, peaking in June and July. The town sits amid the low-lying Westphalian lowland, where open fields and hedgerows dominate the surrounding landscape, adding heavy grass pollen loads once the growing season advances.

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

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.

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 Bielefeld, 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.
