Brazzaville's air quality reflects the flat Congo River basin position at 320 metres adjacent to Kinshasa across the river, with vehicle traffic on surrounding roads and the charcoal burning, vehicle density, and informal industrial corridor generating elevated PM2.5 and black carbon. The equatorial climate's frequent convective rain provides periodic cleansing, while dry season biomass burning from the Congo Basin contributes regional background and Brazzaville generally maintains moderate to elevated Central African capital readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Brazzaville right now?
On 9 August 2026, overall air quality in Brazzaville is fair. O3 is the main pollutant at 34.9/100. Pollution peaks around 7:00 AM (PM1: 43.5/100).
Will air quality be worse tomorrow in Brazzaville?
On 10 August 2026, air quality conditions in Brazzaville will be similar to today, with AQI forecast at fair at 33.5/100. Pollution peaks around 3:00 PM (O3: 33.5/100).
When is air pollution at its worst in Brazzaville?
Air quality in Brazzaville tends to be worse when traffic emissions along with wood-burning stoves build up and dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Coal and wood used for winter heating add substantially to particulate levels.
Are air quality levels in Brazzaville 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.
