Thirteen of Mumbai's 14 air quality monitoring stations recorded annual average PM10 levels above the national limit of 60 micrograms per cubic metre in 2025-26, according to the BMC's Environment Status Report 2025-26. Chembur and BKC recorded the highest levels at 125 micrograms per cubic metre each, more than twice the standard, while only Kandivali met it.

Update, 30 October 2026: Business Standard and Economic Times add that Mumbai's average daily air quality index doubled to 102 through 27 October from 45.4 in September, with IQAir ranking it India's most polluted city, and quote scientist Gufran Beig blaming El Niño's slowed winds. The Times of India provides station-wise PM10 data and mentions a bakery shut.
The Times of India's report focuses on the BMC data and official explanations, quoting deputy commissioner Avinash Kate on dust from roadwork and construction, and noting a bakery has been shut. Business Standard and Economic Times (Reuters) highlight the city's loss of its coastal advantage, citing El Niño slowing winds and a record October air quality index, with scientist Gufran Beig warning conditions may persist to year-end.
