Évreux's air quality is shaped mainly by port traffic and cross-Channel shipping, with its position near the Vire playing a role, though Channel winds provide frequent ventilation, limiting how much pollution can build up locally. Frequent Atlantic weather systems keep conditions broadly consistent across the seasons, with only the calmest, driest summer days occasionally producing a brief ozone peak.

Is air quality bad in Évreux right now?
On 9 August 2026, overall air quality in Évreux is fair. AQI is the main air quality indicator at 34.3/100. Pollution peaks around 12:00 PM (O3: 34.3/100).

When is air pollution at its worst in Évreux?
Residents in Évreux tend to notice the most discomfort when port traffic and cross-Channel shipping build up alongside the spring peak in birch and oak pollen; Channel winds provide frequent ventilation, which typically keeps things from getting worse for long. The presence of dairy pasture and orchard bocage in the area adds another layer to the local pattern.
Are air quality levels in Évreux 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.
