Local Environmental Conditions
Around Westerkappeln, oak, maple, and ash stand out as the leading tree pollen sources in parks and gardens, with exposure shifting between green space and centre. Farmland across the Westphalian and field-edge tree lines nearby contribute additional tree and grass pollen, while field drainage patterns create minor local variation in pollen levels.
Westerkappeln's pollen season stretches across January through August, beginning with alder and hazel from late January with birch pollen dominating April into May. Grass pollen then climbs through June and July. The town sits amid the low-lying Westphalian lowland, where open fields and hedgerows dominate the surrounding landscape, keeping grass pollen levels elevated through the summer cropping season.

How often is the Westerkappeln pollen forecast updated?
The Westerkappeln pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Westerkappeln 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 Westerkappeln 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 Westerkappeln, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
