Due to an upper air circulation over the Arabian sea, the maximum and minimum temperatures of Mumbai are on the higher side, according to the India Meteorological Department (IMD). On Monday, Santacruz recorded maximum and minimum temperatures of 36.2 degrees and 23.6 degrees Celsius, respectively. The maximum and minimum temperature at Colaba was 35.2 degrees and 25.3 degrees, respectively.

IMD officials said Mumbai’s minimum temperature was 3 to 4 degrees above normal this December.

“The reason for this increase in temperature is because of a change in wind patterns that was observed last week. South-easterly winds, which were noticed, are the main reason. Besides the increase in night temperatures, the day temperatures have been higher than normal by 2 to 3 degrees. It is because the south-easterly (winds) have obstructed the sea breeze,” said K S Hosalikar, Deputy Director, IMD.

Hosalikar added that the south-easterly winds were generated due to an upper air circulation over the Arabian sea. IMD satellite images show a patch of white cloud on top of the southeast side of the Arabian sea at a height of 3.6 km above the sea level.

IMD officials said November was cooler than December recording the minimum temperature as low as 16 degrees.

“November was cool due to the influence of the north-easterly winds. Such type of circulations are common through the year and not unusual. We expect the weather to improve by December 9,” Hosalikar added.

The current upper air circulation moved from Lakshadweep in the upward directions, said the officials.

They have, however, clarified that though there is a low pressure over Bay of Bengal near Andaman Nicobar Islands, it does not directly affect Mumbai.
