Worst air pollution Fond du Lac, today and tomorrow

On 9 August 2026, overall air quality in Fond du Lac is fair. O3 is the main pollutant at 36.8/100. Pollution peaks around 12:00 AM (NO2: 40.1/100).

On 10 August 2026, air quality conditions in Fond du Lac will be similar to today, with O3 forecast at fair at 31.8/100. Pollution peaks around 5:00 PM (NO2: 40.5/100).

Fond du Lac experiences a distinct seasonal swing in air quality. In short, between summer ozone and occasional winter inversions, spring and fall are the year's cleanest stretch, whereas extended stretches of summer humidity, combined with light winds, tend to bring the worst air of the year. Fast-moving weather systems typical of the region usually keep pollution from lingering too long.

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.
