Kolkata is expected to enter the first week of June under persistent heat and humidity, with weather officials forecasting isolated afternoon thunderstorms that may offer only temporary relief. The changing conditions come at a time when Indian cities are facing rising concerns over heat resilience, public health preparedness, and the growing pressure of extreme weather on urban infrastructure.
According to regional weather assessments, daytime temperatures across Kolkata are likely to remain near 36 degrees Celsius through the week, while humidity levels are expected to stay elevated. Meteorologists have indicated that scattered thundershowers could develop during late afternoons and evenings, particularly across parts of south Bengal, although widespread rainfall is not yet anticipated.The current weather pattern reflects a broader seasonal transition unfolding across eastern India as pre-monsoon activity gradually intensifies. Climate specialists note that rising moisture from the Bay of Bengal, combined with localised heating, is creating unstable atmospheric conditions that often trigger short but intense thunderstorms. However, experts caution that these brief weather events may not significantly reduce accumulated urban heat, especially in dense neighbourhoods with limited tree cover and high concrete exposure.The Kolkata weather outlook has renewed attention on how Indian metros are adapting to longer periods of thermal discomfort. In several parts of the city, residents have already experienced “real feel” temperatures crossing dangerous thresholds because of humidity. Public transport users, street vendors, construction workers and informal sector employees remain among the most exposed groups during prolonged warm spells.
Urban planners say recurring heat stress is no longer a seasonal inconvenience but an infrastructure challenge. High overnight temperatures reduce cooling recovery for households, while rising electricity demand places additional strain on ageing power networks. Health professionals also warn that prolonged exposure to humid heat can increase dehydration risks, especially for elderly residents and children living in densely populated areas with inadequate ventilation.The weather pattern has further highlighted the need for more climate-responsive urban planning in Kolkata. Researchers increasingly point to the importance of shaded streets, restored water bodies, permeable surfaces and expanded urban greenery in reducing heat retention across rapidly built-up districts. While thunderstorms may temporarily improve air quality and lower surface temperatures, experts argue that long-term adaptation will require structural interventions rather than seasonal dependence on rain-bearing systems.India Meteorological Department projections suggest temperatures across several regions may remain above seasonal norms through June, alongside uneven rainfall distribution. For Kolkata, this means the city could continue experiencing alternating cycles of oppressive humidity and short-lived storm activity in the coming weeks.
As monsoon conditions slowly advance eastward, civic authorities and residents alike are likely to monitor not only rainfall levels, but also how effectively the city manages rising climate vulnerability in its public spaces, transport systems and residential neighbourhoods.
