Mobile's air quality reflects its position on Mobile Bay at the head of the Gulf of Mexico, with the Alabama State Docks and surrounding petrochemical and paper manufacturing complex contributing elevated industrial emissions alongside vehicle traffic on I-10 and I-65. Gulf of Mexico breezes generally provide maritime ventilation along the coast, while the flat Gulf coastal terrain allows reasonable dispersal on most days and the bay's geography channels sea breezes into the city effectively.

Frequently Asked Questions
Is air quality bad in Mobile right now?
On 20 September 2026, overall air quality in Mobile is poor. AQI is the main air quality indicator at 67.7/100. Pollution peaks around 10:00 AM (PM10: 67.7/100).
Will air quality be worse tomorrow in Mobile?
On 21 September 2026, air quality conditions in Mobile will be better than today, with AQI forecast at moderate at 50.9/100. Pollution peaks around 12:00 PM (PM10: 50.9/100).
When is air pollution at its worst in Mobile?
Mobile follows a fairly predictable seasonal air quality pattern. In short, the cleanest conditions usually arrive in winter, once the humid summer ozone season has ended, whereas hot, humid summer days bring the highest ozone risk, amplified by natural emissions from the dense surrounding forests. Occasional agricultural or prescribed-burning smoke can add short-lived particulate spikes outside the main summer ozone season.
Are air quality levels in Mobile 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.
