In North Bengal, excluding Darjeeling, Kalimpong, Alipurduar and Cooch Behar temperatures may also rise by 3-4°C by May 12th.

The IMD forecasts light to moderate rain with thunderstorms and gusty winds (30-50 km/h) in South Bengal districts like North 24 Parganas, Birbhum, Murshidabad and Nadia on May 11th. On May 12th, rain is expected in North and South 24 Parganas, East and West Midnapore, Birbhum, Murshidabad and Nadia.

Quotes

· IMD Official (via X): “Heatwave conditions expected in South Bengal districts from May 10th to 12th. Temperatures may hit 42°C in some areas. Stay cautious.! #WestBengalWeather”

· Kolkata Resident (via X): “It’s 38°C today, and IMD says it’ll get worse. Can’t step out without feeling drained. #HeatwaveAlert”

· IMD Chief Mrutyunjay Mohapatra: “This year, North, East and Central India will face above-normal temperatures from April to June with prolonged heatwaves.”

Additional Information
The IMD’s earlier predictions for 2025 warned of above-normal temperatures across most of India, particularly in North, East, Central and Northwest regions from April to June. However, South and East India including West Bengal were expected to experience relatively normal heat, though still uncomfortable. X discussions highlight that March 2025 was already swelteringly unbearable, setting the stage for a tough May and June. The current heatwave aligns with these forecasts, with temperatures in Kolkata on May 8th recorded at 37.4°C (2°C above normal) and night time temperatures at 28.9°C.

The heatwave comes amid broader challenges in West Bengal, as the India-Pakistan conflict has already disrupted daily life. X posts mention concerns about rising vegetable prices and water scarcity in rural areas like Bankura and Purulia, exacerbated by the heat. The IMD has advised residents to avoid outdoor activities between 11 AM and 4 PM, stay hydrated and wear light clothing. Local authorities in affected districts are setting up cooling centers and distributing oral hydration salts, according to X updates from @ANI and @IndiaToday.

Impact Analysis
The heatwave poses serious health risks, especially for vulnerable groups like the elderly, children and outdoor workers. X users in West Midnapore and Birbhum report cases of heat exhaustion, with hospitals seeing a 20% rise in heat-related illnesses, as per @TimesNow posts. The high humidity, ranging from 46% to 92% in Kolkata, makes the heat feel even worse, increasing the risk of heatstroke.

Economically, the heatwave is hitting daily wage workers hard. Farmers in South Bengal districts like Purulia and Bankura are struggling with crop damage due to the dry, hot conditions as reported on X with #FarmersInCrisis. The expected rainfall over the weekend may provide some relief but heavy rain in North Bengal could lead to flash floods in areas like Jalpaiguri, a concern raised by X users citing past flood events in 2023.

The heatwave also strains infrastructure, with power demand surging due to increased use of fans and air conditioners. X posts from Kolkata mention frequent power cuts, with #KolkataHeat trending alongside complaints about electricity shortages. The combination of extreme heat and the ongoing national security crisis due to the India-Pakistan conflict adds to public stress, making timely weather updates crucial for safety and preparedness.

West Bengal’s heatwave alert from May 10th, 2025 signals tough days ahead with temperatures soaring to dangerous levels in South and North Bengal. While the IMD’s forecast of rain over the weekend offers hope, residents must stay cautious to avoid heat-related health issues. As the state battles extreme weather alongside national security challenges, staying informed and prepared is key. Follow IMD updates and take necessary precautions to beat the heat safely.
