The first hot night was recorded in Odisha and Jharkhand on 15 March 2025, while the situation was seen in Gujarat and Maharashtra on March 27 in 2024 last year. The temperature in the country is rising rapidly, due to which the effect of heat started to show in February itself. For the first time, the heat was defined by the Indian Meteorological Department during the month of winter i.e. February. The first heat of this year was recorded in Goa and Maharashtra on 25 February 2025.
Temperature above normal
According to the Indian Meteorological Department, so much heat has never been seen in February in February in the last 125 years. In recent years, not only the heat is coming first, but its intensity is also increasing. India’s highest temperature in Buddhist, Odisha, reached 43.6 degrees Celsius on 16 March 2025. The temperature was also recorded at 42 and 41.7 degrees Celsius respectively in Jharsugada and Bolangir. During February 2025, the night temperature in 22 states and union territories of India was three to five degrees Celsius above normal. Between 11 and 23 February, at least one day night temperature was recorded in 31 states and union territories of the country. In particular, Odisha and Jharkhand felt their first hot night on 15 March 2025, while in 2024 it was recorded on 5 April and 29 May respectively.
Temperature reached more than 5 degrees in ten states
The night temperature in ten states and union territories including Odisha was 5.1 degrees Celsius above normal. It happened twice in Odisha on February 12 and 20, 2025. According to IMD, the night temperature was recorded at 5.1 degrees Celsius or more than normal in two places in North-West India, Rajasthan and Jammu and Kashmir.
The mountainous areas also started scorching …
Even Indian states like Himachal Pradesh and Indian states such as Kerala have not experienced heatwave in the past are now displaying high frequency of excessive temperature. In Karnataka, it is estimated to have a height of 2.0 ° C by 2030, which will lead to the scorching heat, which will pose a greater threat to the weak population.
More effective urban heat island effect at night
A report by the Indian Institute of Tropical Metrology states that the effect of Urban Heat Island Effect is more clear at night. Buildings, roads and other infrastructure in cities absorb heat and then emit that heat. During the day, the rays of the sun reach the short wave radiation and heat the earth’s surface. This heat at night is free as long -west radiation. Although these short waves easily reach the surface, the longwave radiation gets trapped in concrete and clouds. High buildings and concrete in the city do not allow excess heat out at night. In such a situation, the temperature does not cool down and heat and heat continues even at night.
Effect of climate change … heat reaching new level
Scientists believe that both night and day temperature is increasing due to climate change. Due to this, the number of hot nights is also increasing. Due to climate change, there has been a rapid increase in the number of warm nights along with the increase in temperature across the country in the last decade. According to a study published in the Lancet Journal, hot days and unusually warm nights can affect sleep, leading to increased health problems. From the beginning of February 2025, it has become clear that the heat in India is now reaching a new level, due to which the extreme conditions of the weather are becoming more dangerous. The ocean temperature of February was 22.04 ° C, which was 1.34 degrees above normal. Earlier in February 2016 was recorded 1.29 degrees above normal in February.
