Colaba Records 862.6mm of Rain as Mumbai Gets 60 Percent of Seasonal Monsoon in 8 Days

Between June 29 and July 6, 2026, the neighborhood of Colaba and other parts of Mumbai experienced intense and heavy rainfall spells in short bursts, recording about 60 percent of the city's seasonal average rainfall in a span of just eight days.

The heavy rain triggered orange and red alerts across Mumbai, causing severe waterlogging and impacting local residents. According to official measurements, Colaba recorded 862.6 mm of rainfall during these eight days, while Santacruz recorded 969 mm of rainfall.

Weather experts have pointed to these measurements as evidence of an increasingly erratic, unpredictable, and vulnerable monsoon pattern. These experts blame global warming and the El Nino effect for the intense spells of rain occurring in much shorter durations.

The impact of the heavy downpours was felt on the streets, with severe waterlogging reported in multiple locations. On July 4, 2026, heavy showers lashed the city, and significant waterlogging was witnessed on Lal Bahadur Shastri Marg.

While weather experts have noted that extreme weather events have generally become more common in Mumbai over the past few years, they emphasize that these intense bursts of heavy rain over short periods are now occurring more frequently, signaling a new normal for the city's monsoon season.
