This January, with the northern states experiencing the coldest days, the night temperature at most places in Goa is likely to remain below normal (-1.6°C to -2.0°C) for the next two days.
The lowest minimum temperature of 17.4 degree Celsius was recorded in Panaji and 10 degree Celsius was recorded in Valpoi on January 2 after strong northeasterly winds blowing from northern states triggered a drop in the mercury level in the state.
Officials from the weather department attributed the fall in temperatures to cold winds
from the northern parts of the country, especially after snowfall in the Himalayan states. “The drop in minimum temperatures is due to cold air advection – the movement of cold winds from northern parts of the country during winter months to warmer regions like Goa. The IMD considers December and January as the winter months in northwest India,” the official said.
The temperature in north and northwest India is governed mainly by the western disturbances during the winter. When western disturbances approach, the temperature rises. The mercury level dips when the disturbances trigger snow in the hills and get some strong northwesterly winds.
On Wednesday, the maximum temperature was appreciably two notches above normal at 33 degree Celsius due to clouding preventing heating, while the minimum temperature dipped a notch below normal at 19 degree Celsius.
The official said the current conditions are likely to continue till Thursday but from Friday onwards temperatures are likely to fall further if there is more snowfall in the northern parts of the country.
There was no large difference between the day and night temperatures in the state over the past few days, officials from the IMD said. “If there is more snowfall in the northern parts of the country, we expect night temperature to drop further in the city over the weekend,” the official said.
