Mongaguá's air quality benefits from its São Paulo state coastal position on the Baixada Santista, with consistent Atlantic sea breezes providing reliable maritime ventilation along this resort and fishing community shoreline. Vehicle emissions from the SP-055 and seasonal tourism traffic are the primary local sources, while the Serra do Mar escarpment rising immediately inland creates dramatic topographic variation and the coastal position generally maintains moderate to good conditions throughout most of the year.

When is air pollution at its worst in Mongaguá?
In Mongaguá, reduced air quality is most noticeable when restinga coastal scrub and introduced urban beach resort trees pollen peaks, and on days affected by vehicle emissions from the SP-055 and seasonal tourism traffic; the rest of the year, the local setting keeps things noticeably clearer than average.
Are air quality levels in Mongaguá 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.
