Most polluted cities in Odisha, India, September 2026

13 cities in Odisha, India ranked by their average PM2.5 over the 30 days. Worst: Byasanagar at 32.5 µg/m³, #104 of 2,949 cities in the world. Cleanest: Koīra at 11.4. A city needs measurements on 70% of the days to be ranked.

About 95.8K people in these 3 cities breathed unhealthy air on an average day of September 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.
