Citizens sweltered in the 40.5-degree Celsius heat on Thursday, the second hottest March day in a decade.
The maximum temperature in the suburbs was 8.4 degrees above normal, while at Colaba, the day temperature was 38.6 degree Celsius - 7.9 degrees above normal.
The hottest March day in the last ten years was recorded on March 17, 2011 when the highest temperature recorded was 41.3 degree Celsius.
In the past week, the maximum temperature has risen steadily by almost seven degrees. "Meteorologically speaking, the Konkan and Goa sub-divisions are experiencing Hot Day conditions. This is one notch below heat wave conditions," said VK Rajeev, director, India Meteorological Department (IMD), western region. As per the IMD terminology, a coastal town experiences a Hot Day when the maximum temperature departure is five degrees or more from normal.
Along with Mumbai, coastal cities such as Panjim, Dabolim and Ratnagiri also experienced hot and dry conditions. The Met department said anti-cyclone conditions that had prevailed over the northeast Arabian Sea for a third day running caused the rise in mercury.
"We expect the anti-cyclonic conditions to dissipate over the next two-three days. The temperatures will stabilise then," added Rajeev. In an anti-cyclone, heat is trapped at the surface, which is not allowed to escape into the atmosphere, thus increasing the temperature.
On Thursday, the minimum temperature was 23.5 degree Celsius at Santacruz and 18.2 degree Celsius at Colaba. Unlike the rising maximum temperature, the night temperatures have been normal or below normal because of the absence of clouds. The humidity levels on Thursday were 50% and 23% at Colaba and Santacruz respectively.
The IMD predicted that on Friday, the minimum temperature would be 18 degree Celsius and the maximum temperature would be 39 degree Celsius.
