The India Meteorological Department (IMD) has issued a critical travel advisory as India experiences extreme pre-monsoon weather in April 2026. Heatwaves are affecting northern, central, and eastern India, with temperatures soaring to the mid-40s Celsius in states like Punjab, Haryana, Delhi, Rajasthan, Chhattisgarh, and parts of Uttar Pradesh and Madhya Pradesh. Concurrently, the IMD predicts heavy rains, thunderstorms, and strong winds across the Northeast, particularly in Arunachal Pradesh, Assam, and Meghalaya, along with isolated showers in Odisha, Jharkhand, West Bengal, Kerala, and Karnataka. Travelers are advised to stay hydrated, wear appropriate clothing, and avoid outdoor activities during peak heat hours. The combination of extreme heat and sudden storms can lead to health risks, including heat exhaustion and vector-borne diseases. Precautions such as packing rain gear and monitoring local weather updates are essential for safe travel. The IMD also notes that 2026 could see an increase in heatwave days across the country, emphasizing the need for vigilance among travelers.
