Given that the late surge enabled the nation record a typical rainfall in the months of June to September, the southwest monsoon is anticipated to begin formally leaving the country on October 6, in one of the most delayed withdrawals.
IMD Director General M. Mohapatra stated that the 2021 all India monsoon seasonal rainfall between June 1 and September 30 was 87 cm as opposed to the Long-Period Average of 88 cm of 1961-2010 (99 percent of its LPA).
During the months of June through September, the nation as a whole experienced seasonal rainfall that was typical (96–106% of the LPA), he continued.
The nation has seen rainfall in the normal and above category for the third year in a row. The same was true for 2019 and 2020.
The south-west monsoon rains, which are essential for India’s farmers, typically arrive at Kerala’s southernmost coast around June 1 and begin to leave the north-western state of Rajasthan in the middle of September.
Nearly half of India’s cropland receives no irrigation and is dependent on the yearly monsoon, hence the monsoon rains are essential.
Nearly 15% of India’s economy, the third largest in Asia, and more than half of its 1.3 billion people are supported by farming.
Up until the end of August, India experienced 9% less rainfall than average, but a third more than usual in September reduced the gap to 1%, according to the IMD.
In reality, September’s late rains were among the heaviest in this century, with an estimated 260.44 millimeters.
The nation had previously seen its best September rainfall in 2019, when it received about 260.44 millimeters. India typically receives about 170 millimeters of rainfall in September, but this year it received 230 millimeters, or about 35.2% more than usual.
