At Green Point Athletics Track, it's really the Cape's wind, more than anything else, that determines air quality day to day, with vehicle traffic and the city bowl, harbour, and southern suburbs as the underlying local sources. Calm winter mornings are the exception, when the southeaster briefly stands down and emissions can build up. This is roughly what you'd expect anywhere along this stretch of the Cape.

When is air pollution at its worst in Green Point Athletics Track?
Ask regulars at Green Point Athletics Track when conditions are worst, and most would say calm winter days, when emissions tied to the city bowl, harbour, and southern suburbs aren't cleared by the usual wind. That wind reliably returns through spring and summer, keeping the course well ventilated most of the time. This is a familiar pattern across much of the Cape.
Are air quality levels in Green Point Athletics Track 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.
