Worst air pollution Steenwijk, today and tomorrow

On 9 August 2026, overall air quality in Steenwijk is fair. NO2 is the main pollutant at 38.9/100. Pollution peaks around 5:00 PM (O3: 52.1/100).

On 10 August 2026, air quality conditions in Steenwijk will be similar to today, with O3 forecast at fair at 29.4/100. Pollution peaks around 1:00 AM (NO2: 42.7/100).

People visiting or living in Steenwijk generally notice the biggest dip in air quality during spring and the start of summer, when birch, oak, and pine pollen peaks, or on windless, warm days when traffic on the A32 and industry emissions gather; the open eastern countryside allows reasonably good air movement. Beyond these spells, Steenwijk usually offers conditions comparable to the wider Dutch average.

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.
