Worst air pollution Joigny, today and tomorrow

On 21 July 2026, overall air quality in Joigny is fair. AQI is the main air quality indicator at 35.9/100. Pollution peaks around 5:00 PM (O3: 35.9/100).

On 22 July 2026, air quality conditions in Joigny will be similar to today, with AQI forecast at fair at 32.4/100. Pollution peaks around 3:00 PM (O3: 32.4/100).

Residents in Joigny tend to notice the most discomfort when light industry and river-valley traffic build up alongside the spring peak in oak and hornbeam pollen; the Saone and Doubs valleys channel airflow, which typically keeps things from getting worse for long. Nearby Burgundy vineyards and cereal plains add a further seasonal factor.

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.

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.
