With parts of the country already experiencing uncomfortably warm summer weather, the India Meteorological Department (IMD) said on Wednesday that above normal maximum temperatures are likely over most parts of the country in May and a significantly high number of heatwave days are expected over northern plains, central region and adjoining areas of peninsular India.
IMD chief Mrutyunjay Mohapatra said on Wednesday data shows that the heat waves in April this year were far worse than in 2023, the warmest year on record so far, adding that this trend is likely to continue in May, with around eight to 11 heatwave days predicted over south Rajasthan, west Madhya Pradesh, Vidarbha, Marathwada, and Gujarat regions, Mohapatra said.
Heatwave scorched parts of east, northeast, and southern peninsular India in April, prompting health warnings from government agencies, some states to suspend in-person classes in schools and also revision in polling time for the ongoing Lok Sabha elections.
West Bengal, Odisha, Jharkhand, Tripura, Kerala, Karnataka, Telangana are among the states where mercury has crossed 40-45 degrees Celsius and also where IMD has been regularly sounding red, orange and yellow alerts for heatwaves.

The previous all-time high temperature of 28.5 degree Celsius was recorded on April 29, 1986.
Why Are Bengal, Odisha Experiencing Such Hot Weather
India saw two spells of heatwaves in April — from April 5 to 7 and April 15 to 30. IMD's Mohapatra attributed the prolonged heatwave spell over east, northeast, and south peninsular India in April to the absence of thunderstorms and a persisting anticyclone at lower levels over the west central Bay of Bengal and the adjoining eastern coasts of India.
This caused the sea breeze to cut off over Odisha and West Bengal on most days, he said.
The IMD said south peninsular India recorded an average maximum temperature of 31 degrees Celsius in April, which was the second-highest since 1901. The mean temperature (28.12 degrees Celsius) in April in east and northeast India was the highest since 1901, the weather office said.
The IMD chief said above normal maximum temperatures have become frequent over south peninsular India since 1980s. The region recorded 12.6 mm of rainfall in April, which was the fifth lowest since 1901 and the second lowest since 2001.
Mohapatra said the number of heatwave days this April was the highest in 15 years in Gangetic West Bengal and nine years in Odisha. Odisha also experienced the longest heatwave spell (16 days) in April since 2016.
Amid the prevailing but weakening El Nino conditions, the IMD had earlier warned of extreme heat during the April-June period, coinciding with the seven-phase Lok Sabha elections.
