Worst air pollution New Tecumseth, today and tomorrow

On 26 August 2026, overall air quality in New Tecumseth is fair. AQI is the main air quality indicator at 35.8/100. Pollution peaks around 11:00 AM (O3: 35.8/100).

On 27 August 2026, air quality conditions in New Tecumseth will be similar to today, with AQI forecast at fair at 34.1/100. Pollution peaks around 9:00 AM (O3: 34.1/100).

Particulate levels here tend to peak during the coldest months of the year, when home heating emissions build up under temperature inversions common on calm winter days. Once summer sets in, ground-level ozone becomes the bigger local concern, as hot, sunny days accelerate local ozone formation, occasionally compounded by drifting smoke. Milder spring and fall weather, paired with more reliable wind, usually gives the clearest air of the year.

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.
