Local Environmental Conditions
In Bergisch Gladbach, maple, poplar, and linden anchor the parks and street trees as primary pollen sources, with levels differing between green space and the built-up core. Tree and grass pollen levels rise further from Rhineland farmland and Rhine floodplain woodland at the town's edge, while dense development can trap pollen locally under calm conditions.
Bergisch Gladbach's pollen season unfolds from January to August, launched by hazel and alder already active by January before birch and oak peaking through May. Grass pollen then climbs through June and July. The Lower Rhine plain near Bergisch Gladbach mixes urban sprawl with fertile farmland and river woodland, keeping farmland and riverside woodland pollen elevated into summer.

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