Climate change, along with a weather phenomenon known as El Niño, which brings hotter and drier conditions, are considered by weather experts to be the primary reasons for this intense heat. Several states in central, eastern, and northern India experienced more heatwave days than is typical. Cities like Delhi faced even higher temperatures due to the urban heat island effect, where buildings and roads trap and intensify heat. Health professionals advised people to stay indoors during the hottest times of the day, consume ample water, and limit outdoor activities. Simultaneously, some areas received significantly more rainfall than usual. For instance, Vidarbha in Maharashtra recorded over four times its average May rainfall. This early rain was attributed to thunderstorms and an early start to the monsoon season. Highe...
