Heavy rain and cooler temperatures that impact Indian industries, businesses and communities during the southwest monsoon have begun withdrawing from the Indian sub-continent.
The Indian Southwest Monsoon rainfall to date
The graph below shows a healthy overall cumulative rainfall across India so far this wet season – currently running about 7% more than normal.

Parts of northern and eastern India saw heavy rainfall and thunderstorms during May, with remaining parts of India experiencing heavy flooding rainfall between mid-June and September.
Withdrawal of the Indian Southwest Monsoon underway
As the Northern Hemisphere summer comes to an end, the northern Indian subcontinent cools and the pressure increases, leading to a reversal of the Southwest Monsoon (called the Northeast Monsoon). Cold and dry winds flow down the Himalayas into India – causing the retreat of the Monsoon during September and October.

Over the past two weeks, the southwest monsoon has gradually withdrawn from northwestern India, approximately five days ahead of the normal withdrawal date.

The withdrawal of the southwest monsoon will slow down over the coming week, with 100-200mm of rainfall expected across parts of western and central India, including Mumbai, over the next seven days. Away from the northwest, broader parts of the country can expect weekly falls of 20-60mm as well.

The withdrawal of the southwest monsoon should resume through the first half of October, before likely clearing the country before the end of the month. Relief from flooding rainfall causing disruptions to transport, energy and infrastructure industries is brought with the withdrawal of the monsoon. A healthy monsoon season of rainfall is also imperative to the agricultural industry, with ground moisture remaining high well into the dry season.
