Most polluted cities in North Carolina, United States, November 2025

17 cities in North Carolina, United States ranked by their average PM2.5 over the 30 days. Worst: Wake Forest at 13.0 µg/m³, #682 of 2,662 cities in the world. Cleanest: Roanoke Rapids at 6.5. A city needs measurements on 70% of the days to be ranked.

About 1.32K people in these 3 cities breathed unhealthy air on an average day of November 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.
