Delhi is set to record its coldest November in at least 10 years, the Meteorological Department said, adding that the mean minimum temperature of the month hovered around 10 degrees Celsius this year.

The national capital has an average minimum temperature of 12.9 degrees Celsius during November.

From November 1 to November 29, the city has recorded a mean minimum temperature of 10.3 degrees Celsius, which is the lowest in at least a decade, India Meteorological Department data shows.

The mean minimum temperature was 15 degrees Celsius last year, 13.4 degrees Celsius in 2018 and 12.8 degrees Celsius in 2017 and 2016.

With the minimum temperature remaining less than 10 degrees Celsius for the seventh consecutive day this month, Delhi’s lowest temperature today was recorded at 7 degrees Celsius.

“On November 23, Delhi recorded a minimum of 6.3 degrees Celsius -- its lowest minimum temperature in the month since November 2003, when the city recorded a minimum of 6.1 degrees Celsius,” Kuldeep Srivastava, the head of the IMD's regional forecasting centre, said.

The minimum temperature this month, barring on November 16, has remained 2-3 degrees Celsius below normal in the absence of a cloud cover on most days, according to IMD officials.

Clouds trap some of the outgoing infrared radiation and radiate it back downward, warming the ground.

The month of October was the coldest in 58 years in the national capital.

The mean minimum temperature in October this year was 17.2 degrees Celsius, the lowest since 1962, when it was 16.9 degrees Celsius.
