Worst air pollution Spruce Grove, today and tomorrow

On 20 September 2026, overall air quality in Spruce Grove is moderate. AQI is the main air quality indicator at 55.9/100. Pollution peaks around 4:00 PM (NO2: 55.9/100).

On 21 September 2026, air quality conditions in Spruce Grove will be worse than today, with AQI forecast at poor at 73.7/100. Pollution peaks around 4:00 PM (NO2: 73.7/100).

Spruce Grove's air quality follows a seasonal rhythm tied to its suburban streets west of Edmonton. Cold, still winter days can trap traffic and heating emissions near the ground, while hot summer stretches sometimes bring drifting wildfire smoke from further north or west. Being farther from the downtown core generally keeps conditions a little calmer here than in central Edmonton.

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.
