Most polluted cities in KwaZulu-Natal, South Africa, 2026

1 city in KwaZulu-Natal, South Africa ranked by their average PM2.5 so far (278 of 365 days); 1 above the WHO annual guideline (5.0 µg/m³). The only one: Shakaskraal at 14.8 µg/m³, #577 of 2,745 cities in the world. A city needs measurements on 70% of the days to be ranked.

About 2.46K people in this city breathed unhealthy air on an average day of 2026.

Ranked by people: each city's population times its share of unhealthy days, those with a daily mean over 35.4 µg/m³ (US AQI 101+). That is how many people living there breathed unhealthy air on an average day. Only cities measured at 2 or more places at least 3 km apart are ranked: one monitor shouldn't speak for a whole city. Population is the city itself, not its wider metro area.
