Manenberg lies roughly 10 km east-southeast of Cape Town. Manenberg's air quality benefits from its Western Cape position, with consistent Cape winds providing reliable natural ventilation for much of the year. Vehicle traffic and the city bowl, harbour, and southern suburbs are the main local sources of pollution, while the region's windy climate generally keeps particulate levels low. Conditions like these are common across much of the Cape.

Frequently Asked Questions
Is air quality bad in Manenberg right now?
On 20 September 2026, overall air quality in Manenberg is poor. AQI is the main air quality indicator at 63.3/100. Pollution peaks around 12:00 PM (PM1: 63.3/100).
Will air quality be worse tomorrow in Manenberg?
On 21 September 2026, air quality conditions in Manenberg will be similar to today, with AQI forecast at poor at 61.9/100. Pollution peaks around 11:00 PM (PM1: 61.9/100).
When is air pollution at its worst in Manenberg?
At Manenberg, occasional poor air quality tends to occur on calm winter days, when the Cape's usual wind drops and emissions from the city bowl, harbour, and southern suburbs can build up overnight. Through spring and summer, the reliable southeasterly wind returns and keeps particulate levels low, a seasonal pattern typical of the wider Cape region.
Are air quality levels in Manenberg 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.
