Most polluted cities in Maharashtra, India, 2026

28 cities in Maharashtra, India ranked by their average PM2.5 so far (278 of 365 days); 28 above the WHO annual guideline (5.0 µg/m³). Worst: Nagpur at 39.7 µg/m³, #77 of 2,745 cities in the world. Cleanest: Kolhāpur at 22.7. A city needs measurements on 70% of the days to be ranked.

About 6.42M people in these 7 cities 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.
