Bonn's pollen season carries on from January through August, led off by hazel and alder in early January ahead of birch and oak peaking through May. Summer grass pollen follows, peaking in June and July. The Lower Rhine plain near Bonn mixes urban sprawl with fertile farmland and river woodland, keeping farmland and riverside woodland pollen elevated into summer.

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 Bonn, 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.
