Worst air pollution Saskatoon, today and tomorrow

On 9 August 2026, overall air quality in Saskatoon is fair. PM1 is the main pollutant at 33.3/100. Pollution peaks around 9:00 AM (O3: 57.0/100).

On 10 August 2026, air quality conditions in Saskatoon will be similar to today, with AQI forecast at fair at 27.9/100. Pollution peaks around 2:00 PM (NO2: 27.9/100).

Conditions in Saskatoon shift with the calendar, largely because of its position along the South Saskatchewan River on the open prairie. 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. Strong gusts sweeping across the open prairie generally keep pollution from lingering for long.

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.
