The India Meteorological Department (IMD) has forecasted nearly double the usual number of heatwave days across Northwest India this season. While the region typically experiences five to six heatwave days, this year, it is expected to endure 10 to 12.
IMD scientist Soma Sen Roy stated, “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.” However, she clarified that this is a seasonal projection and does not imply that every day of the season will be abnormally hot.
She further explained that while the forecast suggests above-average heat on a broader scale, the IMD will continue refining predictions through extended-range and daily updates for more precise local insights.
The IMD did not comment on whether 2025 will surpass 2024, which was India’s hottest year on record. Last year, the country endured 554 heatwave days.
When does IMD sound heatwave alert?
According to IMD’s definition, a heatwave occurs when the maximum temperature in the plains reaches at least 40 degrees Celsius or exceeds the normal by five degrees.
The latest Seasonal Heat Outlook for March to May 2025, released on February 28, indicates that most parts of India will experience above-normal maximum and minimum temperatures. However, some regions in the southernmost parts of Peninsular India and isolated areas in the Northeast may see near-normal or slightly below-normal temperatures.
“During the season (MAM), 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,” the forecast stated.
Temperatures to soar in North India
In the coming days, North India is set to experience further warming, with Delhi and its neighboring areas likely to see a temperature rise of 1-2 degrees Celsius. However, north-westerly winds will bring a sharp drop of 3-4 degrees due to dust-raising winds from Rajasthan. Blowing at 20-30 km/h, these winds will sweep through Punjab, Haryana, and Rajasthan over the next three days, creating dry and dusty conditions.
