Delhi is heading into its first heatwave of 2026, with the India Meteorological Department warning that heatwave conditions could develop in isolated to scattered parts of the capital over the next five days. (mausam.imd.gov.in) The weather office said Delhi’s maximum temperatures are likely to rise by another 1-2 degrees Celsius and stay appreciably to markedly above normal through the period. A national heat bulletin issued on April 20 said northwest, central and adjoining east India were likely to see heatwave conditions over the next four to five days. (mausam.imd.gov.in, mausam.imd.gov.in) Forecasts carried by Indian media said parts of Delhi-National Capital Region could reach 42-45 degrees Celsius this week as the hot spell spreads across north India. India Today reported on April 20 that Delhi-NCR and nearby states were bracing for 42-45C temperatures and higher heat-health risks. (indiatoday.in) In India’s weather system, a heatwave is not just “hot weather.” The India Meteorological Department treats it as a period of unusually high temperatures, and for the plains the benchmark starts at a maximum of at least 40C, with the declaration tied to how far temperatures rise above normal. (internal.imd.gov.in, mausam.imd.gov.in) Delhi is entering this spell with a formal response plan already in place. The city government’s Heat Action Plan includes cooling shelters, water coolers and water dispensers, shaded public spaces, hospital heatstroke wards and real-time alerts. (hindustantimes.com, indianexpress.com) The pressure is not only medical. Delhi’s peak power demand is expected to cross 9,000 megawatts this summer, according to distribution company forecasts, after the city recorded an all-time high of 8,656 megawatts in 2024. (business-standard.com, moneycontrol.com) Reuters reported on March 27 that hotter days in 2026 were expected to put fresh strain on India’s electricity and water systems, with extreme heat increasingly testing urban infrastructure. That leaves Delhi facing the heatwave as both a public-health emergency and a utilities stress test. (hindustantimes.com) The immediate advice from forecasters is basic but urgent: avoid prolonged sun exposure, stay hydrated, and reduce heavy outdoor activity, especially for infants, older people and people with chronic illness. If the forecast holds through late April, Delhi will move from an unusually warm start to summer into the kind of heatwave conditions the city now plans for as a recurring seasonal threat.
