The monsoon arrived in the city on Sunday morning, five days ahead of schedule. This is the second-earliest monsoon arrival date on record — tied with 1969, when the rains set in on June 5.
Storming the city with 17.4 mm of rainfall recorded in Colaba and 32.7 mm in Santacruz, weathermen have predicted heavy rains on Monday too.
“A strong monsoon pulse in the Arabian Sea and air circulation over Mumbai were responsible for the early onset of the rainy season,” said RV Sharma, deputy director general of the India Meteorological Department (Western Region).
Through Sunday, humidity levels stayed above 90% in the island city and the suburbs, reaching averages of 92% in Colaba and 91% in Santacruz. Since June 1, Colaba has received 51.4 mm of rainfall and Santacruz, 126 mm.
The rains brought the city some welcome respite from the heat, with maximum temperatures dipping to 33 degrees Celsius in Colaba and 33.5 degrees Celsius in Santacruz and minimum temperatures at a breezy 26.5 degrees Celsius in Colaba and 25.7 degrees Celsius in Santacruz.
The southwest monsoon reached India three days early this year, hitting Kerala on June 1; it was two days early in Maharashtra, arriving on June 3.
