Delmenhorst's air quality reflects its position in the Bremen metropolitan area, with vehicle traffic on the A28 motorway and the surrounding manufacturing and logistics industry contributing local sources. North Sea westerlies provide maritime ventilation, while the flat North German coastal plain allows reasonable dispersal and Delmenhorst's industrial character maintains moderate emission levels above the surrounding Bremen suburban baseline.

Frequently Asked Questions

Is air quality bad in Delmenhorst right now?

On 21 July 2026, overall air quality in Delmenhorst is fair. AQI is the main air quality indicator at 23.8/100. Pollution peaks around 5:00 PM (O3: 23.8/100).

Will air quality be worse tomorrow in Delmenhorst?

On 22 July 2026, air quality conditions in Delmenhorst will be better than today, with AQI forecast at good at 19.7/100. Pollution peaks around 9:00 AM (O3: 19.7/100).

When is air pollution at its worst in Delmenhorst?

You're most likely to notice worse air in Delmenhorst when birch, willow, and alder pollen peaks, or on warm, windless days when local pollution accumulates; local and through traffic is a modest source. The sea's moderating effect keeps ragweed exposure consistently low in this area. Windier afternoons generally bring noticeably clearer air than calm mornings.

Are air quality levels in Delmenhorst 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.
