The IMD predicts a ‘double heatwave’ in Northwest India from March to May 2025, with heatwave days expected to rise to 10-12. The forecast indicates above-normal temperatures across most of India, while local advisories for heat protection are likely to be issued. Immediate temperature increases are expected, although some relief may come from north-westerly winds.
The India Meteorological Department (IMD) has issued a warning regarding an impending ‘double heatwave’ in Northwest India, forecasting approximately double the usual number of heatwave days between March and May 2025. Typical expectations are between five to six heatwave days; however, this year could see 10 to 12 heatwave days, as elaborated by IMD scientist Soma Sen Roy.
Roy noted, “We are expecting slightly above-normal heatwave conditions, especially over West and Central India. Generally, Northwest India sees around 5 to 6 heatwave days. This year, we expect 10 to 12 days, which is double the normal.” It is important to note that this forecast represents seasonal outlooks and does not guarantee that every day will experience higher-than-normal temperatures. The IMD will monitor and provide updated forecasts for enhanced local accuracy.
The agency refrained from confirming whether this summer will exceed the record-breaking heat experienced in 2024, where 554 heatwave days were recorded, marking it as India’s hottest year in history. A heatwave in India is classified when maximum temperatures in the plains reach at least 40 degrees Celsius or exceed normal temperatures by five degrees.
In its seasonal forecast released on February 28, the IMD indicated that most regions in India will likely experience above-normal maximum and minimum temperatures. Notably, some southern areas of Peninsular India and certain regions in the Northeast might encounter near-normal or slightly below-normal temperatures. The forecast stated that, “During the season (March-May), above-normal minimum temperatures are likely over most parts of the country except some isolated southernmost regions of Peninsular India where normal minimum temperatures are likely.”
In the immediate term, North India is expected to experience rising temperatures, particularly in Delhi and adjacent areas, which are predicted to warm by 1-2 degrees Celsius. However, a temporary respite may occur with north-westerly winds originating from Rajasthan, potentially causing a 3-4 degree reduction in temperatures.
These winds, traveling at speeds of 20-30 km/h, will adversely affect weather conditions in Punjab, Haryana, and Rajasthan, creating dusty and dry weather conditions. Given the anticipated intensification of heatwave conditions, local authorities are likely to issue advisories encouraging the public to undertake necessary heat protection measures.
The IMD anticipates unprecedented heatwave conditions in Northwest India from March to May 2025, predicting nearly double the usual heatwave days. This seasonal forecast underscores the necessity for proactive measures to mitigate heat effects. Furthermore, though certain areas may expect a slight respite due to shifting winds, caution is urged across the populace.
