Mumbai weather is expected to remain hot and humid on Sunday, October 18, with the India Meteorological Department forecasting dry conditions across the city and neighbouring areas over the next 24 hours. No significant rainfall is expected in Mumbai during the forecast period, while isolated parts of Ratnagiri and Sindhudurg remain under a yellow alert for thunderstorms, lightning, rain and gusty winds.
The IMD’s Mumbai weather bulletin dated October 18 recorded a minimum temperature of 35.2 degrees Celsius at Colaba, which was above normal. Santacruz recorded a minimum temperature of 25.6 degrees Celsius, also marginally above its normal level, according to the bulletin.
The forecast indicates a sharp contrast within the Konkan region. Mumbai and its surrounding areas are expected to experience dry and humid conditions, while Ratnagiri and Sindhudurg may see thunderstorms accompanied by lightning, light to moderate rainfall and gusty winds. The IMD said wind speeds in isolated locations could reach 30-40 kmph.
The yellow alert covers parts of the Konkan region and signals the possibility of localised weather disruptions rather than a citywide spell of severe weather. For Mumbai residents, the immediate forecast points to continued heat and humidity without significant rain to ease conditions over the next 24 hours.
Air quality also remained uneven across Mumbai and the wider Mumbai Metropolitan Region. Mumbai’s overall Air Quality Index stood at 130 on the Central Pollution Control Board’s dashboard on Sunday, placing the city in the moderate category. The source report said the reading was based on dashboard data available on Saturday morning.
Monitoring stations recorded differences across neighbourhoods. Bandra-Kurla Complex registered an AQI of 129, followed by Borivali at 120 and Byculla at 103. All three readings were in the moderate category, indicating that pollution levels were not uniform across the city and that some localities were recording higher concentrations than others.
Conditions also varied in neighbouring urban centres. Thane recorded an AQI of 101, while Navi Mumbai registered 145. The variation means that residents travelling across the metropolitan region may encounter different air-quality conditions from those recorded in their home neighbourhoods.
The combination of persistent heat and moderate pollution has implications for people who are sensitive to air-quality changes and prolonged exposure to direct sunlight. The source report advised residents to limit extended exposure to direct sunlight while the hot weather continues.
The IMD’s immediate forecast remains dry for Mumbai and nearby areas, while isolated thunderstorms, lightning, rainfall and gusty winds are expected to remain possible in Ratnagiri and Sindhudurg. Residents can continue to monitor local conditions and the CPCB dashboard for neighbourhood-level air-quality changes.
