Mumbai has officially recorded its wettest September since 2021, with the India Meteorological Department (IMD) reporting 606 mm of rainfall this month. The downpour intensified over the weekend, prompting the weather bureau to issue an orange alert for the city on Monday. Data from IMD’s observatories revealed that in the 24 hours ending at 8:30 am, Colaba registered 101.2 mm of rainfall while Santacruz received 77.5 mm. Despite the heavy showers, officials noted that rainfall activity is expected to gradually decrease in the coming days.

According to records from the Brihanmumbai Municipal Corporation (BMC), the western suburbs experienced the heaviest rainfall at nearly 100 mm on average, followed by 80 mm in the eastern suburbs and 74 mm in the island city. The cumulative effect of consistent showers throughout the month has taken Mumbai’s September tally to 606.1 mm, a figure not seen since 2021 when the city recorded 744.2 mm in the same period. The IMD clarified that while conditions remain wet, the city has avoided major flood-like situations, with civic authorities working round the clock to clear waterlogging in vulnerable areas.

Since the beginning of June, Santacruz has reported an overall rainfall of 3,100.4 mm—over 787 mm above the seasonal average—while Colaba has recorded 2,245 mm, exceeding the norm by 155 mm. Sunday alone saw Colaba register its second-highest single-day rainfall since 2021 with over 120 mm. While the heavy rains have brought relief from heat and replenished reservoirs, they have also caused widespread disruption to traffic and local commutes. With more showers forecast through the week, the BMC and disaster management authorities continue to remain on high alert, urging citizens to exercise caution.
