Worst air pollution Point Pelee National Park - Leamington, today and tomorrow

On 9 August 2026, overall air quality in Point Pelee National Park 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 Point Pelee National Park will be similar to today, with AQI forecast at fair at 34.7/100. Pollution peaks around 10:00 AM (O3: 34.7/100).

Point Pelee National Park's air quality follows a seasonal rhythm tied to its position at Canada's southernmost mainland point, a major migratory bird stopover. For most of the year the air stays clean and lake-fresh, but summer tourist traffic and, in some years, drifting wildfire smoke can briefly worsen conditions. Weekday air quality is often noticeably better than on busy summer weekends when visitor numbers peak.

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.
