Worst air pollution Port Huron Charter Township, today and tomorrow

On 9 August 2026, overall air quality in Port Huron Charter Township is fair. AQI is the main air quality indicator at 33.2/100. Pollution peaks around 7:00 AM (O3: 33.2/100).

On 10 August 2026, air quality conditions in Port Huron Charter Township will be similar to today, with AQI forecast at fair at 31.0/100. Pollution peaks around 1:00 PM (O3: 31.0/100).

Winter is usually when particulate matter climbs highest locally, when home heating emissions build up under temperature inversions common on calm winter days. Summer heat pushes ozone to the forefront of local air quality concerns, as heat and sunlight drive photochemical smog, occasionally worsened by drifting wildfire smoke. Spring and fall tend to bring the cleanest air of the year, aided by milder temperatures and more consistent wind.

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.
