Montauban's air quality reflects the Tarn-et-Garonne Garonne river plain, with vehicle traffic on the A20 motorway and the surrounding agri-food and logistics industry contributing local sources. Atlantic westerlies from the Garonne Valley generally provide reliable ventilation across the flat Gascony plain, while calm summer anticyclonic conditions allow ozone to accumulate from vehicle and agricultural emissions and the flat agricultural plain terrain generally prevents significant topographic pollution trapping throughout the year.

Is air quality bad in Montauban right now?
On 9 August 2026, overall air quality in Montauban is medium. AQI is the main air quality indicator at 50.3/100. Pollution peaks around 2:00 AM (NO2: 50.3/100).
Will air quality be worse tomorrow in Montauban?
On 10 August 2026, air quality conditions in Montauban will be worse than today, with O3 forecast at fair at 36.0/100. Pollution peaks around 11:00 PM (NO2: 42.5/100).
When is air pollution at its worst in Montauban?
In Montauban, the combination of tourist and motorway traffic and heavy plane and oak pollen in spring is what most affects sensitive groups; the Tramontane wind provides periodic ventilation, so poor conditions rarely last more than a couple of days. The presence of Languedoc vineyards and Pyrenean farmland in the area adds another layer to the local pattern.
Are air quality levels in Montauban 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.
