Most polluted cities in Maharashtra, India, March 2025

27 cities in Maharashtra, India ranked by their average PM2.5 over the 31 days. Worst: Chānda at 67.5 µg/m³, #31 of 2,809 cities in the world. Cleanest: Kolhāpur at 34.2. A city needs measurements on 70% of the days to be ranked.

About 16.4M people in these 7 cities breathed unhealthy air on an average day of March 2025.

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.
