Monsoon
India receives more than 70 percent of its annual rainfall during the monsoon months, making the season critical for agriculture, drinking water supply, hydropower generation, and groundwater recharge.
In April, the ministry said southwest monsoon seasonal rainfall over the country was expected to be below normal this year.

India is likely to receive 80 cm of rainfall during the season – the long-term average (1971–2020) of seasonal rainfall over India is 87 cm.
Below normal seasonal rainfall is expected over most parts of the country, except some areas over northeast, northwest and southern peninsular India where normal to above normal rainfall may occur.

One reason for the below-normal rainfall could be the emergence of El Niño conditions, which cause less rainfall in the country.
In its May 1 monthly forecast, the department said neutral El Niño-Southern Oscillation (ENSO) conditions over the equatorial Pacific are evolving toward El Niño conditions. El Niño conditions last developed in 2023. Since 2000, these conditions have occurred in 2002, 2009, and 2015.
The Center is fully prepared to mitigate any adverse impact of the El Nino phenomenon on this year’s kharif crop, Union Agriculture Minister Shivraj Singh Chouhan said on Thursday as he called for integrated farming and greater self-sufficiency in pulses and oilseeds, PTI reported.

“Rather than worrying, preparation is required. Contingency plans will be made for the affected areas and crop changes will be considered whenever necessary,” Chouhan told reporters on the sidelines of the two-day National Kharif conference.
The ministry is in the process of identifying areas for alternative crops and ensuring availability of seeds in case of El Nino impact, he told PTI.
The IMD, in its first-stage forecast on April 13, projected a below-normal southwest monsoon for 2026, with rainfall likely to be 92 percent of the long-term average.
The World Meteorological Organization (WMO) has indicated a likely return of El Nino conditions as early as May-July, while the US National Oceanic and Atmospheric Administration (NOAA) in its ENSO update on May 11 said El Nino conditions are likely to emerge during May-June and persist till the end of the year, PTI reported.

El Nino, characterized by an unusual warming of surface waters in the eastern tropical Pacific Ocean, is typically associated with drier and warmer conditions in India.
Kharif (summer) sowing has just started in some parts of India but is still in very early stages. Farmers have started preparing fields for early sowing (especially of short-duration crops such as pulses, coarse grains and some cotton) in areas hit by pre-monsoon rains.
Normal Kharif sowing begins in June and peaks in June-July with the arrival and advance of the southwest monsoon.
