Cacuaco's air quality reflects the flat Angolan Atlantic coastal position adjacent to Luanda's northeastern industrial corridor, with vehicle traffic on surrounding roads and the industrial estate, vehicle density, and oil industry infrastructure generating elevated PM2.5. The South Atlantic trade winds provide coastal ventilation, while the dry season Benguela Current's thermal inversion concentrates emissions and Cacuaco shares Luanda's broader West African Atlantic industrial corridor air quality challenges throughout most of the year.

Frequently Asked Questions
Is air quality bad in Cacuaco right now?
On 20 September 2026, overall air quality in Cacuaco is moderate. AQI is the main air quality indicator at 54.4/100. Pollution peaks around 6:00 AM (HCHO: 54.4/100).
Will air quality be worse tomorrow in Cacuaco?
On 21 September 2026, air quality conditions in Cacuaco will be similar to today, with AQI forecast at moderate at 44.1/100. Pollution peaks around 1:00 PM (PM2.5: 44.1/100).
When is air pollution at its worst in Cacuaco?
Pollution in Cacuaco typically rises when vehicle traffic along with heavy industrial and chemical processing combine, especially once windblown dust events occur. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Cacuaco 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.
