Delhi Braces For First Heatwave Of 2026

Delhi is heading into its first heatwave of 2026, with forecasters warning that hot conditions are likely across the capital through April 24. (mausam.imd.gov.in) The India Meteorological Department said heatwave conditions are likely in Delhi from April 21 to April 24, with maximum temperatures “appreciably above normal to markedly above normal.” Its April 21 bulletin said the latest spell began in Haryana on April 18 and had spread to Delhi by April 21. (mausam.imd.gov.in 1) (mausam.imd.gov.in 2) Delhi’s regional forecast said temperatures were expected to rise another 2-3 degrees Celsius over five days, while a district bulletin for neighboring Gautam Budh Nagar projected highs of 40-41 degrees Celsius from April 21 to April 24. (mausam.imd.gov.in) (hindustantimes.com) A heatwave in India is not just “hot weather.” The meteorological department treats it as a hazard category and issues impact-based warnings that tie temperature forecasts to health risks and suggested actions. (mausam.imd.gov.in) (pib.gov.in) For Delhi this week, the forecast impact level was “moderate health concern” for vulnerable people, including infants, elderly people and people with chronic diseases. The weather office advised avoiding heat exposure and using light-colored cotton clothing and head cover. (mausam.imd.gov.in) (health.delhi.gov.in) Delhi has spent the past two summers building a formal heat response system. The Delhi Disaster Management Authority’s heat action plan identifies children, older adults, outdoor workers, low-income residents, people with disabilities and patients with chronic illness as high-risk groups. (ddma.delhi.gov.in 1) (ddma.delhi.gov.in 2) That plan goes beyond alerts. It lays out early-warning coordination, hospital preparedness, public messaging, ward-level vulnerability mapping and measures such as cool roofs and surveillance of heat-related illness. (ddma.delhi.gov.in) (ddma.delhi.gov.in) Power demand is another pressure point as temperatures climb. Delhi officials said ahead of the 2025 summer that peak demand could touch 9,000 megawatts, above the 2024 record of 8,656 megawatts, and local studies have linked hotter days directly to higher cooling demand. (timesofindia.indiatimes.com) (hindustantimes.com) The national backdrop is also shifting. The India Meteorological Department said on April 20 that heatwave conditions were very likely over parts of northwest, central and adjoining east India during the next four to five days, extending Delhi’s heat into a wider regional spell. (mausam.imd.gov.in) A fresh western disturbance could start affecting the western Himalayan region from April 23, but Delhi’s immediate forecast still points to several days of dangerous afternoon heat. For residents, that makes this week less a surprise than the first real test of the city’s heat plan for 2026. (mausam.imd.gov.in)
