Worst air pollution Amherstburg, today and tomorrow

On 9 August 2026, overall air quality in Amherstburg is fair. AQI is the main air quality indicator at 32.8/100. Pollution peaks around 9:00 AM (O3: 32.8/100).

On 10 August 2026, air quality conditions in Amherstburg will be similar to today, with AQI forecast at fair at 34.7/100. Pollution peaks around 10:00 AM (O3: 34.7/100).

Amherstburg's air quality follows a seasonal rhythm tied to its position on the Detroit River south of Windsor. Cross-border truck traffic keeps emissions elevated much of the year, with summer heat adding ground-level ozone to the mix; winter usually brings some relief except during cold, still inversions. Wait times at the crossing can worsen local air quality further during peak travel periods.

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.
