Amid rising concerns over climate change and extreme weather conditions, the India Meteorological Department is preparing to revise the parameters used to officially declare heatwave conditions across the country. The move comes as India continues to experience unusually high temperatures, longer summers, and more frequent extreme weather events affecting millions of people. Officials and climate experts believe the existing criteria may no longer accurately reflect the severity of current heat conditions, prompting the weather agency to review and update its standards for public safety and better forecasting.

According to reports, the IMD is considering changes to the temperature thresholds and other conditions required for declaring a heatwave in different regions of India. The decision follows growing evidence that climate change has intensified heat patterns, making extreme temperatures more common and dangerous than before. At present, heatwaves are declared based on specific temperature limits and deviations from normal conditions, but experts argue that rising humidity, nighttime temperatures, and prolonged heat exposure should also be taken into account.
The review is taking place as several states continue to battle intense summer heat, causing health concerns, water shortages, and stress on power infrastructure. Officials say the revised system is expected to improve early warnings, strengthen disaster preparedness, and help authorities respond more effectively to heat-related emergencies.
The proposed changes by the IMD highlight the increasing impact of climate change on daily life and the urgent need for updated weather monitoring systems. As temperatures continue to rise globally, experts stress that stronger climate adaptation measures and accurate forecasting will play a critical role in protecting public health and reducing the risks associated with extreme heat conditions.
