Between March–May 2021, above-normal temperatures are expected in most subdivisions in north, northwest, and northeast India. March 2021 was the hottest month of the last decade in certain cities of Maharashtra State. During April, temperatures dropped following some western disturbances that resulted in sudden rains. Over 20 million people in Maharashtra State live in densely populated informal constructions. These people are more vulnerable to heatwaves and heat-related illnesses, as the materials used in building construction increase their exposure to heat.
