The Hague's air quality is generally good, benefiting from its North Sea coastal position and consistent Atlantic westerlies that provide reliable maritime ventilation across this government city. Vehicle traffic on the surrounding highway network is the primary local source, while the North Sea fetch and the flat Dutch coastal plain allow good dispersal on most days throughout the year.

Frequently Asked Questions

Is air quality bad in The Hague right now?

On 21 July 2026, overall air quality in The Hague is fair. AQI is the main air quality indicator at 25.6/100. Pollution peaks around 4:00 PM (O3: 25.6/100).

When is air pollution at its worst in The Hague?

Air quality around The Hague is most changeable during spring and the start of summer, when birch, oak, and alder pollen is at its peak, or on hot, windless days when traffic and industry emissions build up; the flat polder terrain and sea proximity generally support decent air movement. The remainder of the year tends to bring conditions typical of the Netherlands as a whole.

Are air quality levels in The Hague 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.
