Mumbai and its metropolitan region experienced intense pre-monsoon showers on May 6 and 7, 2025, bringing both relief from the sweltering heat and significant disruptions across the city.
The India Meteorological Department (IMD) had issued a yellow alert for Mumbai and neighbouring districts, forecasting thunderstorms accompanied by lightning and gusty winds reaching speeds of 50–60 kmph. The sudden weather change led to a noticeable drop in temperatures, with the Santacruz observatory recording 21.2 mm of rainfall and a maximum temperature of 33.8°C by 5:30 PM on May 7. In contrast, the Colaba observatory noted 3 mm of rainfall and a maximum temperature of 32.4°C.
However, the heavy rains were not without consequence. Over 100 tree branches collapsed across the city, leading to disruptions in local train services. On the Western Railway line, services between Churchgate and Marine Lines were temporarily halted after a piece of cloth became entangled in the overhead electric wires, causing sparking and power issues. Similarly, the Central Railway experienced delays due to tripping of overhead equipment in various sections. The IMD has indicated that such pre-monsoon activity is likely to continue for the next few days, with light to moderate rainfall expected in isolated pockets of the city. Residents are advised to exercise caution, especially during evening hours when the likelihood of thunderstorms and gusty winds is higher.
While the rains have provided temporary respite from the heat, they have also highlighted the city’s vulnerability to sudden weather changes. The incidents of tree falls and disruptions in essential services underscore the need for improved urban planning and infrastructure resilience. As Mumbai continues to grapple with the challenges posed by climate change, there is an urgent need to invest in sustainable and eco-friendly solutions to ensure the city’s long-term viability and competitiveness.
