Local Environmental Conditions
In Dülmen, maple, hornbeam, and beech lead among the parks and street trees as primary pollen sources, with levels differing between green space and the built-up core. Surrounding Westphalian farmland and isolated copses contribute substantial tree and grass pollen, while the patchwork of fields and copses gives modest pollen variability.
Dülmen's pollen season spans January to August, opening with early alder and hazel already active by January then birch peaking through April and May. Grass pollen takes over across June and July. The gently rolling farmland around Dülmen in the Westphalian plain provides little topographic shelter from regional pollen drift, adding heavy grass pollen loads once the growing season advances.

How often is the Dülmen pollen forecast updated?
The Dülmen pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Dülmen come from nearby or far away?
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.
Are pollen levels in Dülmen based on measurements or forecasts?
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 Dülmen, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
