The India Meteorological Department (IMD) in Kolkata has said an impending heatwave is likely to affect several districts of South Bengal from May 8. The condition is expected to persist until May 12.
The forecast indicates a significant rise in both temperature and humidity, with deviations expected to be around 4 to 6 degrees above the seasonal average.
According to the special IMD bulletin, the worst-affected districts will be Paschim Bardhaman, Purulia, Bankura, and Birbhum, where maximum temperatures are likely to soar to 40 degrees Celsius or higher.
The region is also expected to experience elevated humidity levels. The maximum relative humidity in coastal districts could range between 80-90% while interior districts may record levels around 70-80%. These combined factors are expected to result in sultry and uncomfortable weather conditions, increasing the risk of heat-related illnesses.
“The upcoming heatwave may severely impact vulnerable sections of the population, including infants, the elderly, individuals with chronic illnesses, and those exposed to the sun for prolonged periods such as construction workers, farmers, and traffic personnel. There is a heightened risk of heat exhaustion, cramps, heatstroke, dehydration, and heat-related skin ailments like heat rash,” the regional meteorological centre stated in its bulletin.
As part of its advisory, the IMD has urged the public to take necessary precautions. People are advised to avoid stepping outdoors between 11 am and 4 pm, which are the peak hours of heat exposure. It is recommended to stay indoors in well-ventilated or shaded areas as much as possible, wear lightweight, loose-fitting, light-colored cotton clothing, and keep heads covered when stepping outdoors.
Doctors have also weighed in with additional health advice. “It is essential to consume a lot of mineral-rich fruits, vegetables, water, and natural juices to beat the heatwave,” said Dr Arindam Biswas of R N Tagore Hospital. Echoing this, Dr Pratim Sengupta of Bellevue Clinic said, “Always carry a bottle of water during the heatwave and keep yourself hydrated.”
