Worst air pollution Schiedam, today and tomorrow

On 23 August 2026, overall air quality in Schiedam is fair. AQI is the main air quality indicator at 25.9/100. Pollution peaks around 3:00 PM (O3: 25.9/100).

On 24 August 2026, air quality conditions in Schiedam will be similar to today, with AQI forecast at fair at 26.6/100. Pollution peaks around 6:00 PM (O3: 26.6/100).

The main times to watch for Schiedam are the birch, oak, and alder pollen peak through spring and into early summer, and hot, still days when local traffic on the A20 and industry emissions build up; the flat polder terrain and sea proximity generally support decent air movement. Outside these windows, conditions in Schiedam rarely stray far from the national 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.
