The average rainfall in the city is 2,258mm every year.

On Wednesday, the Santacruz weather station, representative of Mumbai, recorded 2,183mm rain till 5.30pm. It means the city has received 97% of its annual average rainfall and is just 75mm short of completing the annual average.

Weathermen said as the southwest monsoon begins its withdrawal process, the possibility of heavy rainfall is likely during the second half of September. “The weather bureau had predicted a 6% surplus rainfall for the entire country before the setting in of the south-west monsoon. With almost a month still to go, Mumbai and some parts of the Konkan coast will definitely be a part of that 6% excess for the season,” said Biswajit Mukhopadhyay, additional director general, India Meteorological Department (IMD).

Mukhopadhyay said the upper air circulation over Arabian Sea, responsible for rain last week in Mumbai, has faded away. “We expect conditions to be favourable for some rain from the second week of September,” he said.

While day temperatures were a degree Celsius above normal, recorded around the 31 degree Celsius mark, both at Colaba and Santacruz, night temperatures were closer to normal levels on Wednesday.

Moisture levels were moderate as the suburbs and south Mumbai recorded 83% and 86%.
