Mumbaiites sweated it out on Wednesday, with the maximum temperature touching an all-time high for September at 37.4 degrees Celsius.

According to officials from the India Meteorological Department (IMD), the suburbs recorded the highest day temperature for the month since 1944, when department started recording data. The maximum temperature in south Mumbai, too, was 3.6 degrees above normal at 34.8 degrees Celsius.

In 2014, the suburbs recorded 37 degrees Celsius on September 30, which was the previous all-time high for the month. The second highest temperature for September was 36.4 degrees Celsius in 1972, followed by 36.2 degrees Celsius recorded on Tuesday.

“The temperature depends on winds. As the withdrawal of monsoon is here, winds are changing to easterly. This heats up the land, as against the westerly winds during the monsoon. Hot winds create dryness in the air. The phenomenon is seen every year at the end of September,” said Ajay Kumar, scientist, IMD Mumbai.

Kumar said there is a possibility of thundershowers in the next two days that might bring down the temperatures.

The night temperature in south Mumbai rose by two degrees to 27 degrees Celsius on Wednesday, while in the suburbs it remained the same as Tuesday at 24.4 degrees Celsius.

Moisture levels in the city and suburbs, too, witnessed a drop. While Colaba recorded 72% humidity, the humidity at Santacruz was 56%.

Weathermen have predicted partly cloudy skies, with maximum and minimum temperatures at 37 degrees Celsius and 24 degrees Celsius respectively, for Thursday.
