Guwahati: With the monsoon season having come to an end on September 30, 2025, both Assam and Meghalaya recorded deficient rainfall of 33% and 43%, respectively. IMD has further predicted that the NE states are likely to receive below-normal rainfall in the period from October to December, 2025.

On the salient features of Southwest Monsoon Season 2025, the IMD stated that rainfall over East & Northeast India was 1089.9 mm against the 1367.3 mm Long Period Average (LPA), which is the 2nd lowest since 1901.

This year, following its onset in Kerala, the Southwest Monsoon progressed swiftly, covering South India and Northeast India by May 29.
