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

Hörstel's pollen season carries on from January into August, opening with early alder and hazel in January then birch pollen dominating April into May. Grass pollen follows, dominating June and July. The gently rolling farmland around Hörstel in the Westphalian plain provides little topographic shelter from regional pollen drift, contributing substantial grass and cereal pollen through the summer months.

The Hörstel 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 Hörstel, 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.
