The India Meteorological Department's (IMD) seasonal outlook for summer 2026 warns of above-normal heatwave days, with rising nighttime temperatures compounding daytime heat stress across east, central, northwest India, and the southeast peninsula.
Latest data showed that 19 of the world's 20 hottest cities were located in India.
With multiple cities across Bihar, Odisha, Uttar Pradesh, West Bengal, Tamil Nadu, Gujarat, and Maharashtra logging temperatures around 44°C, well above seasonal norms, large parts of India are in the grip of an intense and widespread heatwave.
Crucially, rising nighttime temperatures are a growing concern. Warmer nights reduce recovery from heat stress, driving up energy demand significantly.
As summers grow longer and hotter, the demand for cooling is no longer seasonal. It’s permanent and growing.
