At 38.8 degrees Celsius, city records 3rd highest day temperature in April in 10 years

Meanwhile, after Mumbai recorded daily maximum temperature above 37 degrees Celsius two days in a row, the IMD’s Regional Meteorological Centre declared a heatwave warning for Mumbai, and neighbouring districts like Thane and Palghar.

The IMD issues a heatwave warning whenever the daily maximum temperature recorded is higher than normal by a range of 4.5 degrees Celsius to 6.4 degrees Celsius. For a coastal city like Mumbai, the maximum temperature also needs to be above 37 degrees Celsius in both weather observatories of the IMD to declare a heatwave.

Alongside Santacruz, the IMD’s coastal observatory at Colaba recorded 34 degrees Celsius on Wednesday, which is also two degrees above normal.

Weather experts have said that currently, there is a possibility of the temperature falling marginally in the next couple of days. “Temperatures are high due to the formation of an anticyclone that has associated around Mumbai, in the next one or two days there is a chance of this anticyclone getting disassociated, which may lead to slight drop in temperature,” said an IMD official.

“Also, easterly winds are blowing from the mainland and sea breeze is also getting delayed, which has led to rise in temperature in Mumbai over the past few days,” said the official.

Alongside maximum temperature, Mumbai’s minimum temperature has also crossed the normal level, with Santacruz and Colaba observatories recording 25.6 degrees Celsius and 26.6 degrees Celsius on Wednesday, both of which are one degree above normal.

Meanwhile, the Thane Belapur observatory of IMD in Rabale, close to Kharghar — where 14 people succumbed to heatstroke during an event last Sunday — recorded 41 degrees Celsius on Wednesday.
