Worst air pollution Offenburg, today and tomorrow

On 21 July 2026, overall air quality in Offenburg is fair. O3 is the main pollutant at 34.5/100. Pollution peaks around 6:00 AM (NO2: 46.6/100).

On 22 July 2026, air quality conditions in Offenburg will be worse than today, with AQI forecast at poor at 64.9/100. Pollution peaks around 5:00 AM (NO2: 64.9/100).

You're most likely to notice worse air in Offenburg when oak, linden, and spruce pollen peaks, or on windless summer days when pollutants accumulate nearby; everyday local traffic contributes a modest, fairly steady source. A light-to-moderate ragweed presence is typical here from mid-August into September. Conditions generally improve on windier, less humid days.

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.
