Aurora's air quality in Illinois reflects the flat Fox River valley terrain providing generally good wind dispersal, with vehicle emissions from I-88 and the surrounding manufacturing and logistics industry in the Chicago metropolitan western suburbs contributing local sources. The broader Chicago metropolitan regional ozone burden from the southwest and the Fox River valley's industrial corridor are the primary air quality influences, while the flat northeastern Illinois terrain allows reasonable dispersal on most wind days throughout the year.

Frequently Asked Questions
Is air quality bad in Aurora right now?
On 16 July 2026, overall air quality in Aurora is fair. AQI is the main air quality indicator at 36.7/100. Pollution peaks around 11:00 AM (O3: 36.7/100).
Will air quality be worse tomorrow in Aurora?

When is air pollution at its worst in Aurora?
Like most US cities, Aurora sees air quality shift from season to season. Typically, the cleanest stretches usually come in spring and fall, between the summer ozone season and the calmer winter pollution episodes, while the hottest, most humid summer days bring the year's worst ozone readings. Lake-effect winds can help clear the air on many days near the Great Lakes shoreline.
Are air quality levels in Aurora based on measurements or forecasts?
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.
