Kolkata experienced a sudden spell of heavy rain on Monday, bringing welcome respite to citizens who have been enduring weeks of soaring temperatures and high humidity. The rainfall, which began in the afternoon, continued for several hours and affected large parts of the city, including Park Street, Salt Lake, Behala, and Dum Dum.
The downpour led to immediate waterlogging in several low-lying areas, disrupting normal life and slowing down vehicular movement. Commuters faced delays as traffic congestion increased on key roads and intersections. Office-goers and students returning home in the evening had to wade through ankle-deep water in many parts of the city.
According to the India Meteorological Department (IMD), the rainfall was caused by a localized weather disturbance, with moisture-laden winds from the Bay of Bengal intensifying over the region. The IMD stated that these pre-monsoon showers are expected to continue for the next 48 hours, with moderate to heavy rainfall likely in some parts of southern Bengal, including Kolkata.
“The conditions are favorable for more showers due to increased atmospheric instability and the presence of a low-pressure system over the Bay of Bengal,” said an IMD official. “Residents should be prepared for intermittent rain, thunderstorms, and gusty winds during the evening and night hours.”
The temperature, which had crossed 38°C in recent days, dropped significantly following the rain. Monday's maximum temperature was recorded at 32.4°C, almost six degrees lower than the previous day. The change in weather brought a sense of relief to residents who had been struggling with the heat and frequent power outages due to increased demand.
Local shopkeepers and small businesses reported a dip in footfall during the rainfall, while delivery and public transport services operated with delays. Several schools and colleges allowed early dismissal in anticipation of worsening weather conditions.
While the rain offered temporary relief, urban infrastructure issues once again came to light. Poor drainage systems and blocked canals led to waterlogging within minutes in several neighborhoods. Residents expressed concerns over recurring problems that arise during even brief spells of rain.
Environmentalists noted that such unseasonal rain and high variability in temperature are early signs of climate change effects. “This is a reminder that cities like Kolkata need to improve resilience through better planning and climate-sensitive infrastructure,” said Dr. Arindam Roy, a climate researcher.
Authorities have advised citizens to stay updated with weather alerts and avoid waterlogged areas. The Kolkata Municipal Corporation has deployed emergency response teams to address waterlogging and clear blocked drains.
With monsoon season approaching, city officials are urging residents to remain cautious and prepare for further rain-related disruptions. Meanwhile, the sudden downpour has at least provided some relief and a welcome break from the heat for now.
