Delhi looks like heading for pleasant days with a gradual drop in the maximum and minimum temperatures. Average monthly temperature for Delhi in October as per base observatory Safdarjung is 32.8 degrees and 19.1 degrees respectively. There seems to be a significant drop of more than 5 degrees in the minimum and marginal dip of 1 degree in the maximum. Mostly clear sky with the warm sun does not permit any significant drop during the day and moonlit nights allow the radiations to escape sliding down the night temperatures.
Also, the rainfall drops sharply in October and many times, the month goes totally dry. The average rainfall for the month is 13.7mm and is invariably received with the retreating monsoon. Like in 2019, the monsoon withdrew quite late on 10th October and the month recorded 47.3mm rainfall, the entire amount between 03rd and 04th Oct. The monsoon has already withdrawn this time and the chance of having any rainfall. at least during the first fortnight is bleak. The probability remains high for the entire month to remain literally dry.
With the change over of winds to dry northwesterly, the drop in the night temperature is imminent. A temporary change in this pattern may happen between 07th and 09th October due to the movement of a weather system across Madhya Pradesh and Maharashtra. The seasonal flow will resume thereafter and the night temperatures will drop noticeably. The slight chill in the night and nip in the morning breeze will lead to more pleasant weather conditions.
Though at the cost of repetition, monsoon this year did not give fair treatment to the national capital and the rainfall remained deficit by 20%. Also, the departing month of September was the hottest in the last 2 decades ostensibly due to absence of rains during the last three weeks.
