Oran's air quality reflects the flat Algerian Mediterranean coastal position on Mers El Hadjadj Bay, with vehicle density, petrochemical, and industrial corridor generating elevated PM2.5. Consistent Mediterranean westerlies provide maritime ventilation, while windblown Saharan dust during sirocco events elevates PM10 and Oran generally maintains moderate North African Mediterranean coastal metropolitan readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Oran right now?
On 30 August 2026, overall air quality in Oran is poor. AQI is the main air quality indicator at 65.6/100. Pollution peaks around 11:00 PM (NO2: 65.6/100).
Will air quality be worse tomorrow in Oran?
On 31 August 2026, air quality conditions in Oran will be similar to today, with AQI forecast at poor at 72.9/100. Pollution peaks around 1:00 AM (NO2: 72.9/100).
When is air pollution at its worst in Oran?
The biggest local contributors to pollution in Oran are traffic on the surrounding roads and steel, cement, and chemical production, particularly once dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Oran 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.
