Miami's air quality is generally good by US urban standards, benefiting from consistent Atlantic and Gulf trade winds that provide reliable ventilation across this low-lying peninsula city. Summer afternoon thunderstorms wash particulates effectively, while the flat South Florida terrain prevents the topographic pollution trapping seen in inland US cities.

When is air pollution at its worst in Miami?
Like most US cities, Miami sees air quality shift from season to season: frequent afternoon thunderstorms through the wet season help keep particulate levels down for much of the year, but the drier months from roughly November through April bring the highest risk of wildfire and prescribed-burn smoke. Sea breezes help disperse pollution on most days, though smoke from inland fires can still drift into populated areas.
Are air quality levels in Miami 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.
