Compiègne's air quality is shaped mainly by former coalfield industry and motorway traffic, with its position near the Scarpe playing a role, though North Sea winds sweep across the open plains, which usually keeps pollution from accumulating for long. Cold, still winter weather is the main risk for particulate build-up, while summer usually benefits from stronger regional winds, aside from occasional ozone episodes.

Is air quality bad in Compiègne right now?
On 9 August 2026, overall air quality in Compiègne is medium. AQI is the main air quality indicator at 42.2/100. Pollution peaks around 1:00 PM (O3: 42.2/100).
Will air quality be worse tomorrow in Compiègne?
On 10 August 2026, air quality conditions in Compiègne will be worse than today, with AQI forecast at fair at 33.8/100. Pollution peaks around 5:00 PM (O3: 33.8/100).
When is air pollution at its worst in Compiègne?
The days that hit sensitive groups hardest in Compiègne are calm spring ones, when former coalfield industry and motorway traffic and the birch and oak pollen peak overlap; North Sea winds sweep across the open plains, so relief usually isn't far behind. Nearby Picardy and Artois arable plains add a further seasonal factor.
Are air quality levels in Compiègne 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.
