The national capital on Thursday recorded a minimum temperature of 12.5 degrees Celsius, the lowest in October in 26 years, according to the Indian Meteorological Department (IMD).
The normal minimum temperature for this time of year is between 15 and 16 degrees Celsius, he said.
Kuldeep Srivastava, the head of IMD’s regional forecasting center, said the last time Delhi recorded such a low temperature in October was in 1994.
The nation’s capital recorded a low of 12.3 degrees Celsius on October 31, 1994, according to IMD data.
The city recorded its all-time low temperature (9.4 degrees Celsius) on October 31, 1937, Srivastava said.
The IMD lead scientist said the lack of cloud cover was the main reason for such low minimum temperatures this time around.
Clouds pick up some of the outgoing infrared radiation and project it downward, warming the ground.
Another reason is the calm winds that allow the formation of fog and fog, Srivastava said.
The minimum temperature is expected to drop to 11 degrees Celsius by November 1, the IMD added.
