North-western India, September 2026
For 7 days, from 19 to 25 September 2026, 58 cities in India and Pakistan had PM2.5 at least twice their usual for the time of year. The worst reading was Gurugram, Haryana, India: 170.0 µg/m³ on 23 September, about 3.8× its usual 45.1.
Few fires were detected near these cities on those days. Spreads like this usually come from still weather trapping smoke from heating, traffic and industry, or from dust.
Cities reached 58 in 2 countries
Days 7 19 to 25 September 2026

An episode is a run of days when many cities close to each other (four or more within 350 km on a day, 8 or more in all) each had a daily PM2.5 mean of at least 25 µg/m³ and at least 2 times their usual for that time of year. Found in our own measurements, not picked by hand. How we find episodes . Values are each city's daily mean of its own monitors; causes are the usual kinds for a pattern like this, not a confirmed source. Fire detections from NASA FIRMS; smoke maps from NOAA HMS.
