On 20 July 2026, Artemisia is the dominant pollen source in Altenberge. cypress and grass are also present but at lower levels. alder, birch, hazel, and willow are not currently active.

Altenberge's pollen season runs from January into August, starting with hazel and alder from January before birch and oak peaking through May. Grass pollen then climbs through June and July. The gently rolling farmland around Altenberge in the Westphalian plain provides little topographic shelter from regional pollen drift, contributing substantial grass and cereal pollen through the summer months.

The Altenberge 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 Altenberge, 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.
