After a week-long spell of day temperatures being closer to normal levels, the city recorded a sharp spike in mercury levels on Wednesday. The maximum temperature shot up to 38 degrees Celsius, almost five degrees Celsius above normal at the suburbs, the highest maximum temperature for the season so far.
The city observed a five degrees Celsius jump from Tuesday’s day temperature of 33.8 degrees Celsius at the Santacruz weather station. Before Wednesday’s high, the city had recorded a maximum temperature of 36.8 degrees Celsius on April 8. The highest day temperature last year, however, during the month of April was recorded at 35.3 degrees Celsius.
Weathermen attributed the sudden rise in temperatures due to a delay in the setting in of the sea breeze on Wednesday and induced cyclonic circulation over Rajasthan making winds dry and warm over Mumbai. “Generally the sea breeze sets in between 11am to 11.30am in Mumbai. On Wednesday, this phenomenon took place much later that led to a rise in temperatures,” said VK Rajeev, director, western region, India Meteorological Department (IMD). “We expect the maximum temperature to drop from Wednesday’s high but it is likely to remain between 35-36 degrees Celsius,” he added.
The day temperature recorded between 5.30pm Tuesday and 5.30pm Wednesday at the Colaba weather station too was 2.4 degrees Celsius above normal as 35.4 degrees Celsius was recorded as compared to 32 degrees Celsius the previous day.
“The maritime air blowing over the Arabian Sea is the only cooling factor for Mumbai during the summers otherwise the city would have been as hot as interior Maharashtra,” said Bishwajit Mukhopadhyay, additional director general meteorology, climate services division, IMD.
A cloudy sky between Tuesday night and Wednesday morning got night temperatures at south Mumbai to shoot up by 1.4 degrees Celsius above normal as compared to below normal temperatures over the last few days. Between 8.30am Tuesday and 8.30am Wednesday, the minimum temperature recorded at the suburbs was 25.4 degrees Celsius, 0.1 degree Celsius above normal while 27.3 degrees Celsius was recorded at south Mumbai.
Weathermen predicted a partly cloudy sky for Thursday with maximum and minimum temperatures predicted at 36 degrees Celsius and 26 degrees Celsius, respectively.
