The intensifying heatwaves pose significant risks to public health, urban infrastructure, and water resources, particularly in northwestern, northern, and eastern coastal regions of India. Cities like Delhi, Kanpur, and Bhubaneswar are expected to face the brunt of these changes, with longer and more severe heat events increasing the likelihood of heat-related illnesses and strain on energy systems. While some southern and coastal cities may experience smaller changes, the overall trend underscores the growing vulnerability of urban populations to extreme heat.
