Cashan lies roughly 160 km east of Mahikeng. Vehicle traffic and platinum mining and tourism operations shape most of the local air quality picture at Cashan, set within the surrounding bushveld. Winter's dry, still conditions can let dust and smoke linger, while summer thunderstorms and stronger winds generally restore clearer conditions across the district. Much of the surrounding bushveld sees broadly the same seasonal pattern.

When is air pollution at its worst in Cashan?
Air quality at Cashan is most likely to dip during the dry winter months, when dust and smoke from platinum mining and tourism operations can build up on still, windless days. Conditions generally improve from November onward as summer rains settle dust and wash pollutants from the bushveld air, a seasonal pattern typical of the broader bushveld region.
Are air quality levels in Cashan 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.
