Mumbai is likely to witness temporary relief from rising temperatures and air pollution as the India Meteorological Department (IMD) has predicted light to moderate rainfall and isolated thundershowers over the city on October 16 and 17. The forecast extends into the weekend, with light showers expected to ease daytime heat and help mitigate deteriorating air quality.
Neighbouring districts, including Thane and Palghar, have been placed under Yellow Alert due to thunderstorms accompanied by gusty winds. Maximum and minimum temperatures in Mumbai are expected to remain around 35°C and 24°C, respectively, providing temporary respite from the recent heatwave. Statewide alerts indicate that almost all districts of Maharashtra, except Vidarbha, have been placed under Yellow Alert on various days between October 15 and 17. The rainfall is attributed to an upper air cyclonic circulation over the Arabian Sea, which is bringing moisture-laden winds to coastal and inland areas.
This marks the first significant rainfall after the IMD officially declared the withdrawal of the southwest monsoon from Mumbai on October 10, the earliest in seven years. Seasonal rainfall recorded at Colaba observatory reached 2,263.0 mm, while Santacruz recorded 3,112.0 mm. Following monsoon withdrawal, the city has experienced rising temperatures, increased dust pollution, and deteriorating air quality due to the resumption of construction activities. The Brihanmumbai Municipal Corporation (BMC) Environment Department remains on alert, coordinating deep cleaning drives and working closely with agencies such as MHADA, MMRDA, and SRA to minimise pollution. Officials have emphasised that rainfall during this period will help lower particulate matter in the air, improving the overall Air Quality Index (AQI).
Current Central Pollution Control Board (CPCB) data indicates Mumbai’s AQI at 137, classified as Moderate. However, specific areas such as Sion (250), Chembur (229), Deonar (229), Bandra Kurla Complex (211), Mahim (210), Andheri East (182), Colaba (173), and Malad West (162) report higher pollution levels, making localized health precautions necessary. Experts advise residents, particularly vulnerable groups, to limit outdoor exposure during periods of elevated pollution and use protective measures such as masks when commuting. The IMD has urged caution in Thane and Palghar districts, warning of strong winds and potential disruptions due to thunderstorms.
While these showers are expected to provide temporary relief, city authorities have highlighted the need for longer-term strategies to tackle rising temperatures and air quality issues, including sustainable urban planning, greening initiatives, and stricter construction dust management. For now, Mumbaikars can expect cooler mornings and moderate relief from heat and pollution, a welcome change as the city transitions from post-monsoon heat to early winter conditions.
