Amid a later-than-normal southwest monsoon retreat, several states across the western snd southern regions of India are still witnessing intense spells of rains. According to India Meteorological Department (IMD), the southwest monsoon started withdrawing from India on Monday, eight days behind the normal date of September 17.

Delayed Monsoon Retreat

The IMD said, "The southwest monsoon has withdrawn from parts of southwest Rajasthan today, September 25, 2023, against its normal date of withdrawal from southwest Rajasthan of September 17."

According to the weather watchdog, this year is the 13th consecutive delayed Monsoon retreat.

The withdrawal of monsoon from northwest India marks the beginning of its retreat from the Indian subcontinent.

Any delay in the monsoon's retreat means a longer rainy season, which can significantly impact agricultural production, particularly for northwest India where monsoon rainfall plays a crucial role in the Rabi crop production.

Typically, the southwest monsoon makes its onset over Kerala by June 1 and covers the entire country by July 8. It starts retreating from northwest India around September 17, withdrawing entirely by October 15. 

Here's a brief account of the state-wise monsoon scenario.
