The Robertsau area of Strasbourg experiences air quality driven by cross-border industry and river traffic, while the Vosges and river valleys shape local wind patterns, keeping conditions reasonable across the year. Winter is typically the most polluted season, as cold air settles in the valleys and traps heating and industrial emissions; summer brings better dispersion but occasional ozone spikes.

Frequently Asked Questions
Is air quality bad in Robertsau right now?
On 9 August 2026, overall air quality in Robertsau is medium. AQI is the main air quality indicator at 54.3/100. Pollution peaks around 12:00 PM (O3: 54.3/100).

When is air pollution at its worst in Robertsau?
Robertsau, within Strasbourg, sees its worst combined pollen and air quality days when cross-border industry and river traffic coincide with the spring oak and hornbeam peak; the Vosges and river valleys shape local wind patterns. Nearby Alsace-Lorraine cereal and vineyard land add a further seasonal factor.
Are air quality levels in Robertsau 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.
