New Delhi – Large swathes of India are grappling with an intense heatwave, with temperatures consistently exceeding 40 degrees Celsius in many areas and reaching as high as 47.6 degrees Celsius in some regions. The India Meteorological Department (IMD) has issued a series of heatwave warnings, including red, orange, and yellow alerts, across the country, signaling a high risk of heat-related illnesses and heat stroke. These extreme conditions are expected to persist for the next few days, although a gradual reduction in maximum temperatures is forecast from May 29 onwards.
Scorching Temperatures and Widespread Warnings
Maximum temperatures have been recorded between 43°C and 47°C in several parts of Northwest, Central, and Peninsular India as of May 25. The IMD's press release on May 25 highlighted severe heatwave conditions in isolated pockets of Punjab, Haryana, Chandigarh, Delhi, Uttar Pradesh, West Rajasthan, East Madhya Pradesh, and Vidarbha. Under a red alert, authorities have urged extreme caution, particularly for vulnerable populations, due to the high likelihood of heat illness and heat stroke. Cities like Banda in Uttar Pradesh and Brahmapuri in Maharashtra recorded the highest temperatures on May 25, both reaching 47.6 degrees Celsius. The ongoing heatwave has led to record-high electricity demand across India and has also contributed to agricultural drought in some areas, threatening food security.
Monsoon's Approaching Arrival Amidst the Heat
While the country swelters, there is anticipation for the arrival of the southwest monsoon. The IMD had initially forecast the monsoon's onset in Kerala around May 26, five days ahead of the normal June 1st date. However, recent reports indicate a slight delay, with the monsoon onset now being forecast for a window between June 1 to June 10. The monsoon has already arrived over the Andaman & Nicobar Islands on May 16, six days ahead of schedule. The onset of the monsoon is crucial for the country's agriculture, which heavily relies on these rains. Despite the developing monsoon conditions in the south, Northwest India continues to be under an orange-alert heatwave, with temperatures expected to remain high until May 28. A Western Disturbance is anticipated around May 28, which may bring some relief in the form of pre-monsoon thundershowers to parts of Northwest India. The IMD has also predicted isolated heavy to very heavy rainfall over Northeast and adjoining East India during the next 2-3 days, and over Kerala and Tamil Nadu on May 26.
Impact of Extreme Heat and Future Outlook
The persistent heatwave is not only causing discomfort and health risks but also impacting daily life and economic activities. Reports from Uttar Pradesh indicate that frequent power cuts and tripping are affecting industries, including the famous Chikan embroidery sector, despite government claims of stable power supply. Scientists have previously warned that climate change is increasing the likelihood and intensity of such heatwaves in South Asia, making them a recurring reality. The long-term forecast for the 2026 southwest monsoon season suggests below-normal rainfall, potentially exacerbated by an developing El Niño, which could further strain water resources. As the country navigates the current heatwave, the focus shifts to the approaching monsoon and its potential to provide much-needed relief.
