Hasselt's air quality reflects the Flemish Limburg capital in the Belgian-Dutch-German border region, with vehicle traffic on the E313 and surrounding manufacturing, distribution, and agricultural industry contributing local sources. The flat Campine sandy plain provides reasonable dispersal on most days, while the broader Rhine-Meuse delta regional background and the Albert Canal industrial corridor elevate baseline pollution above typical Belgian provincial capital levels throughout the year.

Is air quality bad in Hasselt right now?
On 9 August 2026, overall air quality in Hasselt is medium. AQI is the main air quality indicator at 50.1/100. Pollution peaks around 1:00 PM (O3: 50.1/100).

When is air pollution at its worst in Hasselt?
Reduced air quality in Hasselt is most likely when oak and pine pollen peaks, alongside periods of vehicle traffic on the E313 and nearby manufacturing, distribution, and agricultural industry; a change of season or a spell of wind usually clears things up again.
Are air quality levels in Hasselt based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
