Boksburg's air quality faces significant challenges as part of the East Rand industrial corridor east of Johannesburg, with heavy manufacturing, the R21 highway corridor, and the proximity to OR Tambo International Airport generating concentrated vehicle and aviation emissions. Winter Highveld temperature inversions concentrate emissions across the East Rand plateau, while the elevated 1,600-metre position provides some background dispersal advantage on windy days compared to lower-lying South African cities.

Frequently Asked Questions
Is air quality bad in Boksburg right now?
On 9 August 2026, overall air quality in Boksburg is poor. AQI is the main air quality indicator at 64.8/100. Pollution peaks around 2:00 PM (O3: 64.8/100).
Will air quality be worse tomorrow in Boksburg?
On 10 August 2026, air quality conditions in Boksburg will be better than today, with AQI forecast at fair at 33.9/100. Pollution peaks around 12:00 AM (SO2: 33.9/100).
When is air pollution at its worst in Boksburg?
Air quality at Boksburg 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 Boksburg 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.
