Local Environmental Conditions
Oberhausen's parks and green spaces are anchored by oak, maple, and plane as the main tree pollen sources, with exposure varying between these areas and the more built-up centre. Surrounding Ruhr-area farmland and reclaimed colliery woodland contribute substantial tree and grass pollen, while the dense built environment limits overall tree cover and pollen levels.
Oberhausen's pollen season stretches across late January through August, launched by hazel and alder in early January then birch pollen dominating April into May. Grass pollen then peaks through June and July. The dense Ruhr conurbation around Oberhausen mixes former industrial land with urban parks and street trees, contributing limited but steady urban tree pollen through spring.

When is pollen season in Oberhausen?
How often is the Oberhausen pollen forecast updated?
The Oberhausen pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Oberhausen 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 Oberhausen 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 Oberhausen, 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. |
