Monsoon to reach Kerala four days late: IMD

The southwest monsoon is likely to hit Kerala on June 5, a delay of four days as compared to its normal onset date, the India Meteorological Department (IMD) has said.

The onset of monsoon over Kerala marks the commencement of the four-month-long rainfall season from June to September.

According to the normal onset date, monsoon makes an arrival in Kerala on June 1. “The onset of southwest monsoon over Kerala this year is likely to be slightly delayed as compared to the normal date of onset. The monsoon onset over Kerala this year is likely to be on June 5 with a model error of plus or minus 4 days,” the IMD says.

The monsoon is likely to arrive over the Andaman and Nicobar islands by May 16, six days before its new onset date of May 22 due to a cyclonic storm in the Bay of Bengal.

Even last year, the monsoon had reached the Andaman and Nicobar archipelago on May 18, two days ahead of its then-normal onset date of May 20. But due to its sluggish pace, it reached Kerala on June 8. It covered the entire country by July 19.

According to the IMD forecast, monsoon is likely to be normal this year. The country receives 75% of its rainfall from the southwest monsoon during June to September. It is not only crucial for farming in the country but also for replenishing reservoirs. More importantly, it will be crucial to the economy that is still largely dependent on agriculture. Northeast monsoon is another phenomenon that brings rainfall to Tamil Nadu, Puducherry, and parts of Kerala and Andhra Pradesh from October to December.

From this year, the IMD has also revised the dates of onset and withdrawal dates of the monsoon for several parts of the country based on the data from 1960 to 2019. The previous dates were based on the data from 1901 to 1940.

However, the onset date for monsoon over Kerala, which is June 1, remains unchanged.
