Southwest Monsoon likely to retreat from northwest India on September 25. Reduced rainfall activity expected for next 5 days. Withdrawal marks beginning of retreat from subcontinent. Longer rainy season impacts agricultural production, particularly in northwest India. Monsoon season (June-September) average 870mm, this year 780.3mm.
The southwest monsoon is likely to begin its retreat from northwest India around September 25, the India Meteorological Department (IMD) said on September 22.
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.
"Reduced rainfall activity is expected to continue over northwest and adjoining west-central India for the next five days. Conditions are becoming favourable for the southwest monsoon to withdraw from parts of west Rajasthan around September 25," the IMD said.
The late retreat of the monsoon this year is the 13th consecutive delayed withdrawal.
Withdrawal of the 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.
India has received 780.3 mm of rain during this monsoon season so far, compared to a normal of 832.4 mm. Rainfall between 94 per cent and 106 per cent of the long-period average (LPA) is considered normal.
Normally, the country receives an average of 870 mm of precipitation during the four-month monsoon season (June to September).
