The nip in the air continued on Thursday with Santacruz recording a minimum temperature of 13.8 degrees,more than three degrees below normal,and Colaba recording 18 degrees,just below its normal of 20 degrees.
After a warm first day of the year,with Santacruz recording a minimum temperature of 20.8 degrees and Colaba recording 21.1 degrees,the temperatures fell sharply the next day to 16 degrees in the suburbs and 18.8 degrees in the island city.
However,after a marginal increase on Tuesday,the temperatures have been falling gradually with Santacruz on Thursday recording a minimum temperature two degrees below Wednesdays 15.7 degrees while Colaba fell from 19.5 degrees the previous day.
Weather officials have attributed the fall in mercury levels to a western disturbance in the north.
The western disturbance,which is currently over north Pakistan and Jammu and Kashmir has led to snowfall in some areas. Since the winds in the city continue to blow from northerly to north easterly,they are carrying the cooling winds from the north to the city,causing a dip in temperatures, said Bishwombhar Singh,director,India Meteorological Department (IMD).
Even day time temperatures in January have fallen to as low as 27.2 degrees in Colaba on January 1 and 27.8 degrees in Santacruz.
On Thursday,the island city recorded 29.2 degrees,around its normal of 30 degrees and 30.5 degrees in the suburbs,around its normal of 31 degrees.
The weather department expects temperatures to fall by one or two degrees in the next 48 hours. Our prediction is that the minimum temperature will go to about 13 degrees, said Singh.
