Local Environmental Conditions
The main tree pollen sources in Bergheim are ash, maple, and oak, found chiefly in parks and gardens rather than the built-up centre. Tree and grass pollen levels rise further from Rhineland farmland and farmland tree lines at the town's edge, while the flat Rhine lowland allows pollen to disperse fairly readily.
Bergheim's pollen season extends from late January through August, launched by early alder and hazel from January with birch pollen dominating April into May. Grass pollen follows, dominating June and July. It lies within the Cologne-Düsseldorf conurbation, where urban areas border Rhine floodplain forest, keeping farmland and riverside woodland pollen elevated into summer.

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