Kolkata is expected to witness intermittent rainfall and relatively milder temperatures through Saturday, offering temporary respite after days of oppressive humidity and heat across the metropolitan region. Weather officials indicated that parts of the city and adjoining districts may continue to experience thunderstorms and cloud cover, a development that has once again highlighted the growing pressure climate volatility places on urban infrastructure and public services.
The latest forecast follows intense pre-monsoon activity that swept through several parts of south Bengal earlier this week, bringing gusty winds, brief waterlogging and disruptions to mobility networks in multiple neighbourhoods. Meteorological data suggests maximum temperatures in Kolkata are likely to remain around 34 to 35 degrees Celsius over the weekend, lower than the unusually high temperatures recorded earlier in May.According to weather officials, moisture incursion from the Bay of Bengal combined with unstable atmospheric conditions has created favourable circumstances for scattered thunderstorms across the city. While the rainfall may improve outdoor comfort levels temporarily, urban planners say repeated episodes of sudden heavy showers expose long-standing weaknesses in drainage systems, pedestrian infrastructure and emergency response coordination.Several low-lying pockets in the eastern and southern parts of Kolkata have faced recurring flooding during pre-monsoon rain spells in recent years. Civic experts note that even moderate rainfall events increasingly strain ageing storm-water networks because of rapid surface concretisation, shrinking wetlands and inadequate water retention planning in densely populated urban corridors.
The recent weather fluctuations also carry economic implications for the city. Informal workers, street vendors and transport operators remain among the most vulnerable during abrupt thunderstorms that disrupt movement and reduce commercial activity. At the same time, cooler conditions may reduce short-term electricity demand linked to air-conditioning and cooling systems after a prolonged humid spell.Urban climate researchers have repeatedly warned that eastern Indian metros such as Kolkata are becoming more exposed to erratic rainfall patterns driven by warming regional weather systems. Instead of sustained moderate rainfall, cities are increasingly witnessing short-duration high-intensity showers that overwhelm infrastructure designed for older climate conditions. Recent storm activity across Bengal, including incidents of uprooted trees and transport disruption, has reinforced concerns around climate resilience planning.For residents, the immediate relief from heat has been welcomed after weeks of uncomfortable weather conditions.
However, civic agencies are expected to remain on alert as the city transitions deeper into the monsoon cycle over the coming weeks. Experts argue that Kolkata’s long-term preparedness will depend not only on weather forecasting accuracy, but also on investments in flood management, urban biodiversity protection and more climate-responsive infrastructure systems.
