Praia Grande's air quality reflects its position on the São Paulo state lowland coast below the Serra do Mar escarpment, with Atlantic sea breezes generally providing good coastal ventilation. The primary local concerns are vehicle emissions from the Padre Manoel da Nóbrega highway and industrial emissions from the Santos port complex upcoast, while the Serra do Mar rising sharply inland creates topographic enclosure for the low-lying coastal strip under offshore wind conditions.

When is air pollution at its worst in Praia Grande?
Residents in Praia Grande are most likely to notice reduced air quality when restinga coastal scrub and introduced beach resort trees pollen peaks, or due to the Padre Manoel da Nóbrega highway and industrial emissions from the Santos port complex upcoast; things typically settle down again once the weather pattern shifts.
Are air quality levels in Praia Grande 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.
