India's early heatwave exceeds 40°C in nine states

India is experiencing an early heatwave, with temperatures exceeding 40°C in nine states. This year's heatwave began much earlier than usual, starting in late February, compared to April last year. Temperatures have reached alarming levels, particularly in Odisha, where a record high of 43.6°C was recorded on March 16. The heatwave is also affecting public health, agriculture, and the power sector. The India Meteorological Department (IMD) defines a heatwave as when temperatures hit 40°C, with a notable rise from normal levels. Heatwave conditions have been reported in areas across Western India, including Gujarat and Maharashtra, as well as in states like Rajasthan and Odisha. Last year, India faced a severe heatwave during the summer, leaving many areas struggling with extreme heat. This year, above-normal temperatures have been prevalent since January, indicating a potential continuation of this trend. Experts expect above-normal temperatures to persist in March. Heatwaves typically impact western and east-central states initially before moving to northern regions. Research indicates that heatwaves in India are becoming longer and more intense due to climate change. While thunderstorms and winds may provide temporary relief from the heat, predictions indicate that high temperatures and humidity may return shortly after.
