Worst air pollution Aix-les-Bains, today and tomorrow

On 21 July 2026, overall air quality in Aix-les-Bains is fair. AQI is the main air quality indicator at 39.0/100. Pollution peaks around 5:00 PM (O3: 39.0/100).

On 22 July 2026, air quality conditions in Aix-les-Bains will be better than today, with AQI forecast at medium at 40.3/100. Pollution peaks around 5:00 PM (O3: 40.3/100).

For people sensitive to both pollen and pollution in Aix-les-Bains, spring days combining valley motorway traffic and light industry with the birch and oak peak are the ones to watch; mountain valley winds alternate with calm temperature inversions, which tends to clear things fairly quickly.

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.

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.
