Worst air pollution Delfzijl, today and tomorrow

On 9 August 2026, overall air quality in Delfzijl is fair. NO2 is the main pollutant at 32.0/100. Pollution peaks around 6:00 PM (O3: 46.1/100).

On 10 August 2026, air quality conditions in Delfzijl will be similar to today, with O3 forecast at fair at 30.4/100. Pollution peaks around 3:00 AM (NO2: 47.3/100).

Delfzijl typically sees the birch, oak, and alder pollen peak across the spring and early-summer stretch, alongside calm, warm days when traffic on the N33 and industry emissions accumulate, as the periods to watch; the flat, exposed countryside rarely lets local emissions build up. Apart from these spells, Delfzijl usually sees conditions fairly typical for the country as a whole.

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.
