s-Hertogenbosch' air quality reflects its position in the North Brabant river delta at the Maas and Dommel confluence, with vehicle traffic on the A2 and A59 motorways and the surrounding logistics and food manufacturing industry contributing local sources. The flat Brabant sandy plain provides reasonable wind dispersal, while the broader Rhine-Meuse delta regional background pollution from the Rotterdam industrial complex elevates baseline PM2.5 above typical Dutch rural values throughout the year.

Is air quality bad in ’s-Hertogenbosch right now?
On 20 September 2026, overall air quality in ’s-Hertogenbosch is good. AQI is the main air quality indicator at 19.7/100. Pollution peaks around 5:00 PM (O3: 19.7/100).
Will air quality be worse tomorrow in ’s-Hertogenbosch?
On 21 September 2026, air quality conditions in ’s-Hertogenbosch will be worse than today, with AQI forecast at fair at 36.0/100. Pollution peaks around 11:00 AM (NO2: 36.0/100).
When is air pollution at its worst in ’s-Hertogenbosch?
Keep an eye on ’s-Hertogenbosch during the birch, oak, and pine pollen peak in spring and early summer, and on calm, hot days when traffic on the A2 and local industry emissions accumulate; open sandy farmland around the town helps keep pollutants from building up. The remainder of the year tends to bring conditions typical of the Netherlands as a whole.
Are air quality levels in ’s-Hertogenbosch 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.
