Hamm's air quality reflects its position in the eastern Rhine-Ruhr conurbation, with vehicle traffic on the A1 contributing elevated PM2.5 and SO₂. The flat Westphalian plain provides reasonable wind dispersal while the surrounding industrial complex elevates background pollution above typical western European urban averages, and Hamm's power station legacy maintains localised elevated SO₂ under certain wind directions.

Is air quality bad in Hamm right now?
On 23 August 2026, overall air quality in Hamm is fair. AQI is the main air quality indicator at 24.2/100. Pollution peaks around 5:00 PM (O3: 24.2/100).
Will air quality be worse tomorrow in Hamm?
On 24 August 2026, air quality conditions in Hamm will be similar to today, with AQI forecast at fair at 28.6/100. Pollution peaks around 7:00 AM (NO2: 28.6/100).
When is air pollution at its worst in Hamm?
People in Hamm tend to notice reduced air quality when ash, maple, and plane pollen peaks, or on warm, windless days when local pollution accumulates; traffic on the main roads through town is a modest local source. This region typically sees only a light ragweed presence in late summer. Windier afternoons generally bring noticeably clearer air than calm mornings.
Are air quality levels in Hamm 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.
