Local Environmental Conditions
Royal Golf Club des Fagnes's Belgian Ardennes woodland setting features beech, oak, and birch as the main pollen sources across the elevated Ardennes course, with exposure varying between the more open fairways and the densely wooded sections. Surrounding Ardennes highland farmland and forest contribute substantial tree and grass pollen, while the elevated Atlantic-influenced Ardennes climate means more frequent rainfall than in lower Belgian cities throughout the season.
Pollen from oak, birch, and beech builds through April and May, tapering off as grass pollen takes over across June through August. The wooded Ardennes foothills nearby keep the late-summer ragweed presence mild, and conditions at Royal Golf Club des Fagnes – Championship Course generally track the broader regional pattern for this part of Belgium.

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