Cities with the cleanest air quality in South Africa

Air pollution is one of the most documented environmental health risks of our time. Fine particles (PM2.5), nitrogen dioxide (NO2), and ground-level ozone affect respiratory health, cardiovascular function, and sleep quality - often without visible signs. Choosing where you live, work, or spend extended time matters more than most people realise.

ClearSpot aggregates air quality data from official open government monitoring networks and the Copernicus Atmosphere Monitoring Service (CAMS) into a normalised score for every scored city. The ranking below reflects monthly averages at default sensitivity thresholds. Cities at the top have consistently lower modelled air pressure - not just on one good day.

The 0 cleanest cities for air quality in South Africa in May 2026 are listed below, scored from 0% (maximum pressure) to 100% (no documented pressure within default thresholds). Click any city to explore the full environmental breakdown and compare with nearby places.

How is air quality measured on ClearSpot?

ClearSpot sources air quality data primarily from the Open-Meteo Air Quality API and WAQI (World Air Quality Index), both of which aggregate readings from national government monitoring stations. For each city, we compute a monthly average across PM2.5, PM10, NO2, ozone, and carbon monoxide, then normalise against WHO 2021 guidelines to produce a 0-100% pressure score. A score of 100% means no measured pollutant exceeded WHO thresholds during the reference period. A score of 0% means persistent exceedance across multiple pollutants.

Data is refreshed monthly. For a real-time reading at any precise GPS coordinate, use the ClearSpot live map.
