Olpe sits within the flat Westphalian plain, where local traffic and nearby regional through-roads and surrounding arable farming and small-scale manufacturing contribute the main local air quality sources. Open farmland surroundings generally allow pollutants to disperse readily, while Atlantic westerlies and the wider Ruhr-area industrial background dominate regional air quality throughout the year.

Is air quality bad in Olpe right now?
On 20 September 2026, overall air quality in Olpe is fair. AQI is the main air quality indicator at 28.0/100. Pollution peaks around 1:00 PM (NO2: 28.0/100).
Will air quality be worse tomorrow in Olpe?
On 21 September 2026, air quality conditions in Olpe will be similar to today, with AQI forecast at fair at 35.1/100. Pollution peaks around 10:00 AM (NO2: 35.1/100).
When is air pollution at its worst in Olpe?
In Olpe, reduced air quality is most noticeable when hornbeam, ash, and beech pollen peaks, or during warm, windless days when local pollution accumulates; typical local traffic patterns add only a modest contribution. Ragweed exposure stays modest in this part of Germany through late summer. Mornings and breezier days generally bring the clearest conditions.
Are air quality levels in Olpe 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.
