Southwest Monsoon likely to hit Kerala on May 31: IMD | India news

NEW DELHI: The annual southwest monsoon is likely to arrive in Kerala on May 31, ushering in the crucial four-month period of rainfall that is crucial for Agricultural Economy of India.
“This year is southwest monsoon is likely to set over Kerala on May 31 with a model error of four days,” the India Meteorological Department said on Wednesday.
IMD Director General Mrutyunjay Mohapatra said this timing closely matches the normal onset date of monsoon over Kerala which usually occurs around June 1. “Monsoon over Kerala is on June 1,” Mohapatra said.
Last month, the IMD had predicted above-normal rainfall for the June to September Southwest Monsoon season. The months of June and July are particularly important for agriculture as this period marks the primary phase of sowing the kharif crop.
Two key factors contributed to the likelihood of abundant rainfall, which included a positive Indian Ocean Dipole (IOD), indicating cooler than normal temperatures in the eastern Indian Ocean compared to the western region. This facilitates rainfall in several South Indian states. Currently, the IOD status is ‘neutral’ but is expected to move to a positive phase in August.
The second reason highlighted was a reduced snow cover in the Northern Hemisphere and Eurasia. Mohapatra explained that historically there has been an “inverse relationship” between the extent of snow cover in these regions and the intensity of the monsoon.
The onset date plays a crucial role in tracking the monsoon’s journey across the nation, providing a respite from the intense summer heat as it moves north.
