Strasbourg's air quality reflects its position in the Upper Rhine valley at the Franco-German border, with vehicle traffic on the A35 and the surrounding European Parliament and Council facilities generating local emissions alongside the Rhine industrial corridor. The Rhine provides the primary ventilation corridor, while the Vosges to the west and the Black Forest to the east create partial topographic enclosure that can concentrate emissions under calm anticyclonic conditions.

Frequently Asked Questions
Is air quality bad in Strasbourg right now?
On 9 August 2026, overall air quality in Strasbourg is fair. NO2 is the main pollutant at 22.7/100. Pollution peaks around 12:00 PM (O3: 54.5/100).
Will air quality be worse tomorrow in Strasbourg?
On 10 August 2026, air quality conditions in Strasbourg will be similar to today, with AQI forecast at fair at 35.9/100. Pollution peaks around 1:00 PM (O3: 35.9/100).
When is air pollution at its worst in Strasbourg?
Residents in Strasbourg tend to notice the most discomfort when cross-border industry and river traffic build up alongside the spring peak in oak and hornbeam pollen; the Vosges and river valleys shape local wind patterns, which typically keeps things from getting worse for long. The presence of Alsace-Lorraine cereal and vineyard land in the area adds another layer to the local pattern.
Are air quality levels in Strasbourg 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.
