Aschaffenburg's air quality reflects the Main river valley at the edge of the Spessart forest in northern Bavaria, with vehicle traffic on the A3 motorway and surrounding manufacturing industry contributing local sources. The Main valley provides the primary ventilation corridor, while the Spessart uplands create topographic variation across the surrounding countryside.

Frequently Asked Questions

Is air quality bad in Aschaffenburg right now?

On 21 July 2026, overall air quality in Aschaffenburg is fair. AQI is the main air quality indicator at 28.5/100. Pollution peaks around 5:00 PM (O3: 28.5/100).

Will air quality be worse tomorrow in Aschaffenburg?

On 22 July 2026, air quality conditions in Aschaffenburg will be similar to today, with O3 forecast at fair at 27.4/100. Pollution peaks around 6:00 AM (NO2: 41.8/100).

When is air pollution at its worst in Aschaffenburg?

Reduced air quality in Aschaffenburg is most likely when maple, oak, and beech pollen peaks, or on calm, hot days when local sources build up; the town's own traffic remains a modest, everyday contributor. This warmer southern climate brings a modest late-summer ragweed presence from mid-August. A shift to windier weather typically brings noticeable relief here.

Are air quality levels in Aschaffenburg 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.
