Amersfoort's air quality reflects its position in the Utrecht Hills transition zone between the flat Dutch polder and the Veluwe ridge, with vehicle traffic on the A1 and A28 motorways and the surrounding government and technology services corridor contributing local sources. The Veluwe's forested ridge to the east provides modest clean-air buffering, while the flat Utrecht and Flevoland plain to the west and consistent North Sea westerlies generally maintain moderate Dutch urban air quality levels throughout the year.

Is air quality bad in Amersfoort right now?
On 23 August 2026, overall air quality in Amersfoort is fair. AQI is the main air quality indicator at 23.9/100. Pollution peaks around 2:00 PM (O3: 23.9/100).
Will air quality be worse tomorrow in Amersfoort?
On 24 August 2026, air quality conditions in Amersfoort will be similar to today, with AQI forecast at fair at 26.9/100. Pollution peaks around 6:00 AM (NO2: 26.9/100).
When is air pollution at its worst in Amersfoort?
In Amersfoort, air quality is most likely to dip when pollen from birch, oak, and pine peaks across the spring and early-summer stretch, or on hot, still days when local traffic on the A1 and industry let emissions build up; the wooded Utrechtse Heuvelrug ridge nearby provides some buffering. The calmer months in between generally keep Amersfoort close to typical Dutch air quality levels.
Are air quality levels in Amersfoort 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.
