Centurion's air quality reflects its position in the Tshwane metropolitan area between Pretoria and Johannesburg, with vehicle traffic on the N1 and N14 motorways and the surrounding government and technology corridor contributing elevated NOₓ. Winter Highveld temperature inversions concentrate vehicle and residential heating emissions across the plateau, while the elevated 1,321-metre position aids background dispersal on windy days. Centurion's relatively affluent residential character keeps it below the most industrialised parts of the Pretoria-Johannesburg corridor.

Frequently Asked Questions
Is air quality bad in Centurion right now?
On 30 August 2026, overall air quality in Centurion is poor. AQI is the main air quality indicator at 69.5/100. Pollution peaks around 7:00 AM (SO2: 69.5/100).
Will air quality be worse tomorrow in Centurion?
On 31 August 2026, air quality conditions in Centurion will be similar to today, with AQI forecast at poor at 63.2/100. Pollution peaks around 8:00 AM (SO2: 63.2/100).
When is air pollution at its worst in Centurion?
Air quality at Centurion is most likely to dip during the dry winter months from May to August, when temperature inversions trap vehicle and household emissions close to the ground on still mornings. Conditions improve markedly once the summer rains arrive from November, as stronger winds and regular thunderstorms clear the plateau air for the rest of the season.
Are air quality levels in Centurion 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.
