Nagpur: There is no relief in sight for Vidarbha from the scorching sun as the Nautapa period, traditionally associated with nine days of peak summer temperatures, is set to begin on Monday amid severe heatwave conditions. Weather forecasts indicate that maximum temperatures are likely to hover between 43°C and 45°C through most of the Nautapa period, making conditions extremely hot and uncomfortable across the region.
According to the India Meteorological Department's observations on Sunday, temperatures remained well above normal across Vidarbha. Bramhapuri emerged as the hottest place in the country at 47.2°C. Other districts recording high temperatures included Chandrapur at 45.6°C, Wardha at 45.5°C, Nagpur at 45.4°C, and Amravati and Gadchiroli at 45.2°C each. Gondia recorded 45°C, while Bhandara touched 44.8°C. Humidity levels remained low in most districts, worsening dry and harsh conditions.
Maximum temperatures ranged between 43°C and 47°C over parts of northwest and central India, adjoining Uttar Pradesh, and east and north peninsular India.
This time, Nautapa period will be from May 25 to June 2. Traditional weather observations suggest that an intensely hot Nautapa is often followed by a good monsoon season.
Scientifically, during April to June, the sun remains nearly overhead across central India between latitudes 13° and 23.5°, also known as the "zero shadow period". This causes direct solar heating of the land surface, sharply increasing ground and air temperatures.
"During this period, hot winds from Rajasthan and Gujarat sweep across Vidarbha and central India, triggering heatwave conditions. Historical records show that some of the highest temperatures in the region — touching 48°C and 49°C — occurred during Nautapa," said environmentalist Suresh Chopane.
Chopne noted that temperatures in evening, late-night and early-morning too are remaining above normal, reducing the cooling relief usually experienced during night hours. "The persistent heat in cities like Nagpur is largely due to the "urban heat island effect", which causes heat to remain trapped for longer periods. Rapid urbanisation in recent years has intensified the phenomenon. As a result, temperatures are not falling easily even after the heatwave conditions weaken," he said.
