Worst air pollution Regina, today and tomorrow

On 9 August 2026, overall air quality in Regina is poor. AQI is the main air quality indicator at 74.6/100. Pollution peaks around 12:00 PM (NO2: 74.6/100).

On 10 August 2026, air quality conditions in Regina will be similar to today, with AQI forecast at poor at 72.6/100. Pollution peaks around 4:00 PM (NO2: 72.6/100).

Seasonal air quality in Regina is closely linked to its position on the flat prairie around man-made Wascana Lake. Cold snaps in winter can trap local emissions close to the ground, while summer heat and occasional drought conditions raise the risk of drifting wildfire haze. Open prairie winds usually clear the air within a day or two of any buildup.

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.
