The rains have finally bid adieu to Mumbai. According to the Indian Meteorological Department (IMD), monsoon withdrew from the city on Tuesday evening.

“Satellite images have showed that the atmosphere is dry. Relative humidity has decreased to about 35% from last week’s 70%,” said RV Sharma, deputy director general, western region, IMD. “We have also been getting dry winds from the east and north east of Mumbai for the past few days. All these parameters indicate that the monsoon has withdrawn.”

The last few weeks have seen heavy rain in many parts of the city. But, the withdrawal of monsoon is declared when there are five clear, hot days without rain over a larger area. There has been no rainfall in the past 24 hours and the weathermen have forecast only partly cloudy skies.

Even though the monsoon starts receding in the second week of October, Sharma said the withdrawal is not as definite as the June 11 onset.

Just two months into the monsoon, on August 17, Mumbai crossed the average annual seasonal rainfall of 2,294 mm. From June 1 to September, the city received an average rainfall of 3,200 mm.

A combination of normal monsoon features — low-pressure areas over the Bay of Bengal, trough off the west coast, and strong wind pressure areas over the west coast of the Arabian Sea — were responsible for the city’s record rainfall.
