Heatwave in Delhi peaked on Monday, with the mercury touching 48 degrees Celsius, the highest in the history of the national capital.
"Today was the hottest ever day in the history of Delhi," the official added.
According to private forecaster Skymet, absence of rains over the past two weeks and dry westerly winds led the temperature to soar substantially on Monday.
"There has been no pre-monsoon activity in the past two weeks. So no rains. Also, westerly dry winds from Pakistan and Rajasthan contributed to intensifying the heatwave situation," Skymet Director Mahesh Palawat said.
Western, central, and northern parts of the country on Monday witnessed a surge in temperature, making the heatwave conditions severe.
However, the situation is expected to ease from Tuesday as the monsoon is likely to make progress, though it is expected to reach Delhi only in the first week of July.
Heatwave conditions are set to die down now with the arrival of monsoon as westerly winds will stop and easterly winds filled with moisture will come to the northern region.
"There will be an increase in humidity but the temperature will not cross 40-43 degree," Palawat said.
