The India Meteorological Department issued heatwave alerts for several regions as temperatures are forecast to exceed 40°C across the country [1], [2].
These warnings come as extreme heat threatens public health and safety across northern and eastern India. The escalating temperatures increase the risk of heatstroke and put significant pressure on power grids during peak demand.
In Delhi, the weather agency issued a yellow warning [1]. The national capital recently recorded 43.4°C, marking the hottest day of the season so far [3]. Forecasters expect temperatures in the Delhi NCR region to cross 45°C [1] over the next four days.
Other states are facing more severe conditions. The IMD issued an orange alert for Odisha, where Jharsuguda recorded a temperature of 46°C [2]. Similarly, Telangana is under an orange alert as Hyderabad braces for temperatures ranging between 41°C and 44°C [4].
Bihar is also experiencing extreme heat. Districts including Patna, Gaya, Rohtas, and Buxar are seeing temperatures above 40°C [5]. The IMD said these conditions occurred on May 18, 2026 [5].
The varying alert levels, yellow and orange, indicate different degrees of urgency for local administrations to implement heat-mitigation strategies. While yellow alerts suggest that weather becomes potentially disruptive, orange alerts signal a higher level of danger that requires immediate preparation.
“The national capital recently recorded 43.4°C, marking the hottest day of the season so far.”
The widespread nature of these alerts across diverse geographies, from the northern plains of Delhi to the eastern coast of Odisha, suggests a systemic heat event rather than a localized spike. The use of orange alerts in Odisha and Telangana indicates a higher risk of life-threatening conditions compared to the yellow alert in Delhi, requiring more aggressive public health interventions and emergency cooling centers.
