• Northern states such as Haryana and Rajasthan recorded the highest average of 11 heatwave days annually during the summer months of April to June. Punjab and Delhi followed closely with averages of 10.8 and 9.2 days, respectively. In contrast, southern and eastern states experienced far fewer heatwave days, with Assam averaging just 0.2 days and Karnataka 1.2 days.

Impact & Risks

The high frequency of heatwave days in northern states poses significant risks to public health, agriculture, and infrastructure. Prolonged exposure to extreme heat can lead to heat-related illnesses, including heatstroke, particularly among vulnerable populations such as the elderly, children, and outdoor workers. Additionally, the agricultural sector may face challenges due to heat stress on crops, potentially impacting food security. Urban areas like Delhi and Gurugram are also at risk of increased energy demand for cooling, straining power grids.
