Kolkata is expected to witness another round of evening thunderstorms and scattered rainfall this week as changing pre-monsoon conditions begin moderating the prolonged spell of humid heat across the eastern metropolis. The weather shift is likely to offer temporary relief to residents dealing with rising discomfort levels, while also testing the city’s ageing drainage and mobility infrastructure during peak commuting hours.
According to forecasts issued by the India Meteorological Department, parts of Kolkata and adjoining districts may experience gusty winds, lightning activity and light to moderate rainfall over the coming days. Maximum temperatures are expected to remain around the mid-30 degrees Celsius mark, marginally below seasonal highs recorded earlier this month.The changing weather pattern comes after several days of oppressive humidity and elevated night temperatures that strained electricity demand and public health systems across eastern India. Urban climate experts note that while pre-monsoon thunderstorms are common in Bengal during May, increasingly erratic rainfall intensity and warmer baseline temperatures are making Indian cities more vulnerable to heat stress and short-duration flooding events.For Kolkata, the latest rain spell carries both relief and risk. Short bursts of heavy rain often cool surface temperatures and improve air quality temporarily, but they can also expose gaps in drainage preparedness, especially in densely populated neighbourhoods and low-lying transport corridors. Commuters in several southern and eastern parts of the city have already reported intermittent waterlogging during recent storm activity.
Meteorological observations over the past 24 hours showed moderate rainfall and strong winds across parts of south Bengal, including North and South 24 Parganas, Howrah and East Midnapore. Wind speeds in some pockets reportedly touched nearly 60 kilometres per hour during evening storm activity.The broader weather transition is being closely tracked because eastern Indian cities are entering a critical pre-monsoon phase marked by rising heat exposure, high moisture retention and pressure on urban infrastructure networks. Climate researchers increasingly warn that Indian metros must redesign public spaces, drainage systems and housing layouts to adapt to more volatile weather cycles linked to global warming.Residents across Kolkata have also expressed concern over recurring humidity, unreliable cooling access and heat-related discomfort in recent weeks, highlighting how climate variability disproportionately affects households without adequate ventilation or energy backup systems.Urban planners say future resilience efforts in Kolkata will need to move beyond emergency weather alerts and focus on integrated heat mitigation measures such as shaded public infrastructure, permeable surfaces, urban wetlands and climate-sensitive transport planning.
While forecasts suggest thunderstorms may continue intermittently through the weekend, civic agencies are expected to remain alert for localised disruptions linked to traffic congestion, falling trees and temporary water accumulation. The coming weeks will likely determine how effectively Kolkata transitions into the monsoon season while balancing public safety, infrastructure resilience and rising climate pressures.
