Worst air pollution Spruce Grove, today and tomorrow

On 9 August 2026, overall air quality in Spruce Grove is poor. AQI is the main air quality indicator at 64.5/100. Pollution peaks around 12:00 AM (NO2: 64.5/100).

On 10 August 2026, air quality conditions in Spruce Grove will be better than today, with O3 forecast at fair at 21.4/100. Pollution peaks around 11:00 PM (NO2: 43.3/100).

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.
