Last time the national capital witnessed a chillier November was in 2003 when the recorded minimum temperature was 6.1 degree Celsius, reveals data from the IMD Safdarjung observatory, the is representative of the city’s weather. According to the head of the IMD regional weather forecasting centre, Kuldeep Srivastava, this year has been exceptionally cold as temperature in Delhi during Octobers was also two or three degrees below normal. In November, barring two days, the night time temperature has mostly remained below normal of average.
The factors that contributed to the record drop in temperature, Srivastava said are cold winds blowing from the mountainous regions with fresh snowfall, clear nighttime skies in Delhi that increases the loss of heat due to radiation and cooling of the ground. The direction of the wind blowing from the north-west direction is likely to divert to easterly by Wednesday increasing temperature by close to 10 degrees until Friday.
Some areas in Delhi like the Lodhi road, Mungeshpur were colder than Safdarjung with a recorded temperature of 6.4 and 6.3 degree Celsius respectively. According to Srivastava, the temperature will fall further in December when unlike November’s cold early morning, day time temperature will also drop significantly. The maximum temperature recorded in the city on Sunday was also the lowest day time temperature recorded so far in the month at 24.2 degree Celsius.
