In October 2025, most parts of the country are expected to receive normal to above-normal rainfall. However, some areas in Northwest India and extreme south peninsular India and isolated pockets in the Northeast India, may experience below-normal rainfall.

"Rainfall over east and northeast India this monsoon season was the second lowest since 1901. The lowest rainfall (1065.7 mm) in the monsoon season in the region was recorded in 2013," Mohapatra said during an online press conference.

"Rainfall over east and northeast India has been deficient in many years in recent times. There is a trend (which shows) that rainfall over this region is decreasing since 2020. Studies also show that rainfall over east and northeast India has decreased in the last 20 years," he said.

Northwest India received 747.9 mm, 27.3 per cent more than the normal of 587.6 mm.
