All 2,645 cities by PM2.5, last 24 hours

Every city with enough measurements in this window, worst first.

CPCB in India: no readings since 12 Oct (488 monitors). EEA and Catalonia Medi Ambient I Sostenibilitat in Spain: no readings since 13 Oct (336 monitors). Their cities are missing from this board, not clean.

Hide the 1,153 cities with only 1–2 sensors

These cities have only one or two low-cost sensors, and one cheap unit can read well off, so they take no rank. They sit at their place by value, marked –, and every ranked city keeps its number.

Low-cost sensors: consumer units, counted only in cities with no government-grade monitor; they read close to reference monitors on the whole, but 15 to 25% high in humid air. How we use them.

The US EPA's Air Quality Index for PM2.5 (2024 breakpoints). Show values as: µg/m³ · US AQI · India AQI · China AQI · European AQI · UK DAQI · Canada AQHI+. About the scales

Not covered: the government monitoring networks of China, Turkey and Iran, which publish only on their own websites. We are building the reader for China's network. The networks of Turkey and Iran don't answer requests from outside their countries, so we can't read them. Most cities there are missing from this board, not clean. Why.

SmogRank, all cities ranked by mean PM2.5 (µg/m³), last 24 hours to 14 Oct 2026, 05:00 UTC: each city's mean of its hourly values, cities measured in 18 or more of the 24 hours. Monitor data from national networks via OpenAQ and the publishers listed at smogrank.com/sources. smogrank.com/rankings. Ranked on low-cost sensors, with no reference monitor in the city: #1 Gaur, Madhesh, #2 Kuala Lumpur, #4 Multan, #5 Faisalabad, #6 Gujranwala, #7 Lilongwe, #8 Lahore, #9 Dhaka and #10 Bahawalpur.
