Worst air pollution Campbell River, today and tomorrow

On 9 August 2026, overall air quality in Campbell River is fair. O3 is the main pollutant at 37.3/100. Pollution peaks around 12:00 PM (NO2: 57.8/100).

On 10 August 2026, air quality conditions in Campbell River will be similar to today, with O3 forecast at fair at 21.9/100. Pollution peaks around 3:00 PM (NO2: 49.5/100).

Campbell River's air quality changes through the year largely because of its salmon-fishing harbour on Vancouver Island's east coast. Persistent winter rain generally keeps pollution levels low, while dry summer stretches can bring some haze from traffic and, in smoky years, wildfires burning inland. Frequent Pacific storms during the cooler months usually clear the air completely within a day.

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.
