Miami Beach's air quality benefits from its exceptional Atlantic Ocean and Biscayne Bay coastal position on the narrow barrier island, with consistent sea breezes providing reliable maritime ventilation along the famous Art Deco shoreline. Vehicle emissions from the MacArthur and Julia Tuttle Causeway approach roads are the primary local sources, while summer ozone from subtropical heat and the greater Miami metropolitan traffic is the primary warm-season concern.

When is air pollution at its worst in Miami Beach?

Miami Beach experiences a distinct seasonal swing in air quality. Typically, frequent afternoon thunderstorms through the wet season help keep particulate levels down for much of the year, while dry-season wildfire and prescribed-burn smoke, mainly from late autumn through spring, is the main seasonal concern. Inland areas tend to see more smoke buildup than locations closer to the coast.

Are air quality levels in Miami Beach 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.
