Soissons's air quality is shaped mainly by former coalfield industry and motorway traffic, with its position near the Scarpe playing a role, while North Sea winds sweep across the open plains, generally keeping conditions moderate to good on most days. Cold, still winter weather is the main risk for particulate build-up, while summer usually benefits from stronger regional winds, aside from occasional ozone episodes.

Frequently Asked Questions

Is air quality bad in Soissons right now?

On 21 July 2026, overall air quality in Soissons is fair. AQI is the main air quality indicator at 33.9/100. Pollution peaks around 6:00 PM (O3: 33.9/100).

Will air quality be worse tomorrow in Soissons?

On 22 July 2026, air quality conditions in Soissons will be similar to today, with AQI forecast at fair at 29.5/100. Pollution peaks around 5:00 PM (O3: 29.5/100).

When is air pollution at its worst in Soissons?

For people sensitive to both pollen and pollution in Soissons, spring days combining former coalfield industry and motorway traffic with the birch and oak peak are the ones to watch; North Sea winds sweep across the open plains, which tends to clear things fairly quickly.

Are air quality levels in Soissons 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.
