On 16 July 2026, Grass is the dominant pollen source in Aachen. hazel, cypress, willow, alder, artemisia, and birch are not currently active.

Aachen's pollen season spans January through August, kicking off with hazel and alder in January ahead of birch levels peaking during April and into May. Grass pollen follows, dominating June and July. It lies within the hilly Sauerland-Siegerland terrain, where dense forest cover and narrow valleys shape local air movement, keeping tree pollen levels elevated into early summer.

The Aachen 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 Aachen, 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.
