Ermelo's air quality reflects the Mpumalanga Highveld position at 1,612 metres near the Vaal Dam, with vehicle traffic on the N17 and surrounding agricultural operations contributing local sources. Winter Highveld temperature inversions concentrate vehicle and residential emissions, while the proximity to the Mpumalanga coal-fired power station corridor — including the Duvha and Kendal stations — elevates regional background SO₂ and PM2.5 significantly above typical South African non-industrial levels.

When is air pollution at its worst in Ermelo?
At Ermelo, the poorest air quality usually occurs on still winter mornings from May to August, when smoke and vehicle emissions accumulate under a low temperature inversion typical of the Highveld plateau. From November onward, summer rains and afternoon winds generally restore clearer conditions that last through much of the warmer part of the year.
Are air quality levels in Ermelo 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.
