Randburg's air quality reflects its position in the northern Johannesburg suburban corridor, with vehicle traffic on the N14 and surrounding arterials and the proximity to the Highveld industrial complex contributing elevated PM2.5. Winter Highveld temperature inversions concentrate vehicle and wood-burning emissions across the Johannesburg plateau, while the elevated 1,700-metre position generally aids background dispersal compared to lower-lying South African cities on windy days.

When is air pollution at its worst in Randburg?
Air quality at Randburg 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 Randburg 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.
