The India Meteorological Department issued a yellow alert for Delhi after temperatures climbed above 44 °C during a severe heatwave [1], [2].

This extreme weather threatens public health and infrastructure in the Indian capital, where prolonged heat can lead to heatstroke and critical water shortages. The IMD warning signals a period of high risk for residents as the region struggles with temperatures significantly above seasonal averages.

Weather stations at the Ridge and Ayanagar recorded a maximum temperature of 44.6 °C [1]. This figure represents a climb of 3.4 °C above the normal temperature for this period [1]. Other reports have cited slightly lower peaks, including a reading of 43.6 °C [2] and a general forecast peak of 44 °C across Delhi and Rajasthan [3].

The IMD has projected that the severe heatwave conditions will persist from May 25 through May 28, 2026 [1]. While some earlier reports indicated the warning was in place only until May 24 [4], the most recent forecasts suggest no significant relief will arrive before May 29, 2026 [1].

Officials have urged residents to take precautions to avoid heat-related illnesses. The yellow alert serves as a notification that the weather may be hazardous, requiring the public to monitor updates, and limit exposure during peak sunlight hours.

The current surge is part of a broader trend of prolonged heat across northern India. These conditions have pushed the mercury well above seasonal norms, prompting the government to issue these alerts to mitigate the risk of mass casualties from heat exhaustion.

“Delhi recorded temperatures above 44 °C”

The issuance of a yellow alert by the IMD indicates that while the heat is not yet at the most extreme 'red' level, the sustained temperatures above 44 °C create a cumulative health risk. The discrepancy in end dates for the warning suggests a volatile weather pattern, but the extended forecast into late May indicates that the city's cooling systems and public health resources will be under pressure for a longer duration than typically expected for the pre-monsoon transition.
