Annecy's air quality faces Alpine basin challenges, with the city's enclosed position between the Aravis and Bauges limestone massifs and the Annecy Lake's natural setting creating partial topographic enclosure. Vehicle traffic on the A41 and winter residential wood burning generate elevated PM2.5 under temperature inversions, while Lake Annecy's thermal lake breezes provide distinctive daily ventilation cycles and the surrounding Alpine environment generally maintains better summer conditions than France's flat basin cities, creating marked seasonal air quality contrast.

Frequently Asked Questions
Is air quality bad in Annecy right now?
On 9 August 2026, overall air quality in Annecy is fair. AQI is the main air quality indicator at 35.3/100. Pollution peaks around 12:00 PM (O3: 35.3/100).
Will air quality be worse tomorrow in Annecy?
On 10 August 2026, air quality conditions in Annecy will be similar to today, with AQI forecast at fair at 37.4/100. Pollution peaks around 11:00 AM (O3: 37.4/100).
When is air pollution at its worst in Annecy?
In Annecy, the combination of valley motorway traffic and light industry and heavy birch and oak pollen in spring is what most affects sensitive groups; mountain valley winds alternate with calm temperature inversions, so poor conditions rarely last more than a couple of days. The presence of alpine valley pasture and orchards in the area adds another layer to the local pattern.
Are air quality levels in Annecy 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.
