Worst air pollution CCJ Rocklands – Rocklands Course - Johannesburg, today and tomorrow

On 19 July 2026, overall air quality in CCJ Rocklands – Rocklands Course is very poor. AQI is the main air quality indicator at 88.7/100. Pollution peaks around 11:00 PM (SO2: 88.7/100).

On 20 July 2026, air quality conditions in CCJ Rocklands – Rocklands Course will be similar to today, with AQI forecast at very poor at 100/100. Pollution peaks around 10:00 PM (SO2: 100/100).

Golfers at Rocklands tend to notice the same pattern as much of northern Johannesburg: haze builds on still winter mornings from commuter traffic, then clears through the day as Highveld breezes develop. The September jacaranda bloom adds a mild pollen presence before the November rains arrive.

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.

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.
