Cape Town's air quality is generally good in the Atlantic coastal suburbs, driven by the famous Cape Doctor southeasterly wind that provides powerful natural ventilation. The Cape Flats downwind of the mountain are more exposed to industrial and domestic burning emissions, while wood fires in informal settlements contribute winter PM2.5 peaks.
