Local Environmental Conditions
Around 72% of the area near the center of Namur is built-up land, with some woodland. Close to a stream or river, riverside trees such as poplar and alder contribute to what is in the air. The allergenic tree mix nearby includes oak, maple and hazel. Grasses also feature strongly, alongside pigweed and plantain among the weeds.
First to flower is hazel, in late winter. Tree pollen peaks in late spring, when the weather warms to around 15°C and oak and maple are in full flower. Then come the grasses, strongest in early summer and fading by late summer. Pigweed and plantain bring a final peak from midsummer into mid-fall. In warm, humid weather through summer, mold spores add to the mix, especially after rain.

How often is the Namur pollen forecast updated?

Does pollen in Namur 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 Namur 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 Namur, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
