Worst air pollution Köniz, today and tomorrow

On 20 September 2026, overall air quality in Köniz is moderate. AQI is the main air quality indicator at 40.3/100. Pollution peaks around 9:00 AM (PM2.5: 40.3/100).

On 21 September 2026, air quality conditions in Köniz will be better than today, with AQI forecast at fair at 39.0/100. Pollution peaks around 9:00 AM (PM2.5: 39.0/100).

At Köniz, winter mornings bring the poorest readings, as vehicle traffic and administrative and commuter activity build up in the river valley whenever the usual airflow stalls out overnight. From spring, conditions steadily pick up along the Aare, and summer stays mostly clear aside from a rare ozone spike, with autumn usually just as settled.

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.
