Carletonville lies roughly 70 km west-southwest of Johannesburg. The Highveld plateau setting around Carletonville means vehicle traffic and gold mining and processing operations are never far from the air quality picture, particularly once winter's still mornings set in. From spring onward, wind and rain reliably take over the job of clearing the air. Nearby towns on the plateau tend to see similar conditions.

Is air quality bad in Carletonville right now?
On 9 August 2026, overall air quality in Carletonville is very poor. AQI is the main air quality indicator at 96.3/100. Pollution peaks around 2:00 AM (SO2: 96.3/100).
Will air quality be worse tomorrow in Carletonville?
On 10 August 2026, air quality conditions in Carletonville will be better than today, with PM2.5 forecast at fair at 33.6/100. Pollution peaks around 10:00 PM (SO2: 48.4/100).
When is air pollution at its worst in Carletonville?
Air quality at Carletonville is most likely to dip during the dry winter months from May to August, when temperature inversions trap emissions from gold mining and processing operations close to the ground on still mornings. Conditions improve markedly once summer rains arrive from November, as stronger winds clear the plateau air, a seasonal pattern typical of the wider Highveld plateau.
Are air quality levels in Carletonville 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.
