On 16 July 2026, Cypress is the dominant pollen source in Iserlohn. grass are also present but at lower levels. hazel, willow, alder, artemisia, and birch are not currently active.

Iserlohn's pollen season stretches across January to August, launched by hazel and alder already active by January then birch climbing through April into May. Grass pollen follows, dominating June and July. Surrounding hills and extensive woodland in the Sauerland region give Iserlohn a more sheltered, forest-influenced pollen profile, adding a steady woodland pollen contribution through spring.

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 Iserlohn, 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.
