The maximum was almost eight degrees above normal and severe heat wave warnings were issued by the IMD Mumbai for Thane, Palghar and Raigad for Tuesday.
Last year, the highest recorded maximum temperature was 40.9 degrees Celsius on March 28. The all-time highest maximum temperature recorded in the city for March was 41.7 degrees Celsius on March 28, 1956.
On Monday, the IMD Colaba recorded a maximum temperature of 39.6 degrees, which was 6.7 degrees above normal. Relative humidity recorded by the Colaba and Santacruz observatories was 39% and 15%, respectively.
The IMD in a five-day forecast indicated that severe heat wave conditions were very likely in some parts on Tuesday and Wednesday while heat wave conditions were very likely in isolated pockets. Conditions are likely to ease by Thursday.
Heat wave warnings are issued when the temperature of any coastal station reaches 37 degrees and the departure from normal is between 4.5 to 6.4 degrees. When both these conditions are met for a coastal station like the city and when it persists for two days at more than one station, then a heat wave is declared for that region. If departures exceed 6.5 degrees, then severe heat wave conditions are issued by the weather bureau.
“Due to the advection of warm and dry winds from North-West India, heat wave to severe heat wave conditions are very likely over parts of Konkan-Goa, including Mumbai, during next three days. Due to the prevailing clear skies and low humidity values, the temperatures are expected to rise and similar conditions are likely to prevail for next twi to three days over the region,” said the IMD.
People were warned against heat exposure and dehydration, and advised to cover the head in the sun while wearing light cotton clothes.
