Winterswijk's air quality reflects its position as an eastern-border farmland town in Gelderland, as the N18 corridor and area businesses supply most of the local pollution load. With the Achterhoek farmland and Duitse Border woodland in the vicinity aiding air flow, and the hilly Achterhoek border landscape part of the local picture, readings stay close to the national norm.

Frequently Asked Questions

Is air quality bad in Winterswijk right now?

On 30 August 2026, overall air quality in Winterswijk is good. AQI is the main air quality indicator at 19.6/100. Pollution peaks around 11:00 PM (NO2: 19.6/100).

When is air pollution at its worst in Winterswijk?

Air quality around Winterswijk is most changeable through spring and into early summer, when birch, oak, and pine pollen is at its peak, or on hot, windless days when traffic on the N18 and industry emissions build up; open farmland and nearby forest generally support decent air movement. The rest of the year, Winterswijk generally sees air quality in line with typical Dutch levels.

Are air quality levels in Winterswijk 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.
