Cairo sits at the confluence of the Mississippi and Ohio Rivers, a once-bustling river port whose population and industry have declined sharply over the past century. Tree cover around Giant City State Park woodlots and along the Ohio River helps trap a share of local particulates before they spread further.

Frequently Asked Questions
Is air quality bad in Cairo right now?
On 9 August 2026, overall air quality in Cairo is fair. AQI is the main air quality indicator at 28.3/100. Pollution peaks around 12:00 AM (O3: 28.3/100).
Will air quality be worse tomorrow in Cairo?
On 10 August 2026, air quality conditions in Cairo will be similar to today, with AQI forecast at fair at 35.5/100. Pollution peaks around 9:00 AM (O3: 35.5/100).
When is air pollution at its worst in Cairo?
In Cairo, particulate matter usually peaks in winter, driven by home heating and vehicle emissions trapped by cold, still conditions. Warmer months bring a different challenge: ozone, formed when strong sun and heat interact with local emissions. Local air quality here is shaped more by river-valley humidity and surrounding farmland than by any significant industry today.
Are air quality levels in Cairo 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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
