Mumbai has recorded its second-highest June rainfall in seven years, as the intensified southwest monsoon unleashed torrential downpours that have paralysed daily life and exposed severe stress points across the city’s infrastructure. With sustained rainfall over the past week, temperature levels have hovered between 30 and 32 degrees Celsius, while intermittent showers are expected to continue in the days ahead.
On June 19, Mumbai’s Colaba observatory reported over 143 mm of rainfall within 24 hours—its highest single-day figure for June since 2023, and only the second-highest since 2018. The India Meteorological Department (IMD) has indicated that multiple weather systems over the Arabian Sea and Western India have contributed to this intensified activity. The heavy rainfall, which began early in the morning, continued into the evening, inundating low-lying areas, delaying suburban train services, and choking key arterial roads. The cumulative rainfall recorded across the city has significantly exceeded historical averages for this time of year. Colaba has so far recorded approximately 475 mm of rainfall this June, while Santacruz observatory has received over 400 mm. This compares to the city’s monthly average of around 300 mm and marks a nearly 50 percent increase in rain volume over last year’s levels for the same period. While June is typically the onset month for the southwest monsoon, this year’s early and intense arrival has outpaced historical timelines and caught many off guard.
The relentless rain has disrupted life in almost every part of the city. Waterlogging has been reported in key commercial and residential districts, including Andheri, Dadar, Kurla, Sion, and parts of South Mumbai. Commuters have had to wade through waterlogged streets, with buses and auto-rickshaws either rerouted or suspended. Local train services—the city’s arterial transport lifeline—were delayed on both the Central and Western Lines, affecting thousands of daily passengers. The situation worsened as visibility dropped and traffic congestion increased, leading to cascading delays during both morning and evening peak hours. City officials have deployed emergency teams to pump out stagnant water from flood-prone locations and ensure power supply stability. The Brihanmumbai Municipal Corporation (BMC) has activated its monsoon war rooms and is working alongside the Disaster Management Cell to monitor rainfall intensity and coordinate quick responses. Civic authorities have urged residents to stay indoors unless absolutely necessary and avoid low-lying or landslide-prone zones, particularly during high tide timings.
Despite these measures, there is growing concern that such emergency responses are only temporary fixes to a deeper urban planning crisis. Experts and urban climate analysts argue that Mumbai’s stormwater drainage systems, many of which are over 50 years old, are incapable of managing the extreme rainfall events now becoming common due to climate change. Encroachments along natural water channels, the loss of mangrove buffers, and poor maintenance of nullahs have all contributed to the city’s recurring flooding woes. With each year’s monsoon, Mumbai finds itself confronting the same problems—only with rising intensity. Meteorologists have predicted that Mumbai will continue to receive intermittent rainfall through the weekend and into next week, with brief periods of dry weather. The IMD has issued a yellow alert, warning of potential heavy spells on June 22 and 23, particularly in northern and eastern suburbs. Maximum temperatures are expected to hover around 32 degrees Celsius, while minimum temperatures will likely remain near 25 degrees Celsius. High humidity and water accumulation are also increasing the likelihood of vector-borne diseases, further straining public health systems.
The city’s longstanding monsoon-related challenges are no longer just infrastructure or engineering issues—they are rapidly becoming issues of climate adaptation, equity, and sustainability. Residents living in informal settlements and marginalised communities bear the brunt of these disruptions, often without access to secure shelter, drainage, or public transportation alternatives. Women, children, and the elderly in these areas are particularly vulnerable when faced with waterlogging, flooding, and health hazards. The editorial vision of building carbon-neutral, resilient, and inclusive cities finds renewed urgency in the face of such climate-linked events. Experts argue that Mumbai must accelerate its transition to sustainable urban development—introducing sponge city principles, expanding permeable surfaces, restoring natural stormwater pathways, and adopting decentralised water retention systems. Equally important is the need to integrate disaster risk reduction into the city’s housing and transport policy, ensuring that safety and accessibility are guaranteed to all citizens, regardless of their location or socioeconomic status.
This year’s early and intense monsoon should be seen not just as a weather anomaly but as a clarion call to rethink the future of urban India. Mumbai, with its unique coastal geography and population density, can either become a model for climate-resilient infrastructure or continue to endure monsoon-induced chaos year after year. As the monsoon continues its steady grip over the city, civic vigilance remains high. Residents are being urged to follow weather advisories, report waterlogging and electric faults promptly, and avoid unnecessary travel. Emergency response teams remain on standby, and daily rainfall data is being monitored closely to manage flood risks and minimise economic disruption.
While the rain is expected to ease slightly in the coming days, the larger question lingers—can Mumbai endure the new normal of extreme weather without long-overdue systemic reform? The answer will likely shape the future of India’s most dynamic urban centre and its journey toward becoming a sustainable, equitable, and resilient city.
