Only three meteorological subdivisions recorded deficient rainfall this monsoon season. India’s geographical area is divided into 36 meteorological subdivisions. Twenty-one subdivisions recorded normal rainfall, 10 saw excess

In the 2023 monsoon season, India recorded 820 mm of rainfall, which was 94.4 per cent of the long-period average of 868.6 mm. The country logged 925 mm of rainfall, 106 per cent of the long-period average, in 2022; 870 mm in 2021; and 958 mm in 2020.

The IMD had predicted above-normal rainfall (106 per cent of the long-period average) for the monsoon season this year. It also accurately forecast below-normal monsoon rainfall for northeast India, normal rainfall for the northwest, and above-normal rainfall for central and southern peninsular regions.

The monsoon is critical for India’s agricultural sector, with 52 per cent of the net cultivated area dependent on it. This primary rain-bearing system is also essential for replenishing reservoirs that provide drinking water and support power generation across the country.
