India is on alert as scientists warn that the ongoing El Nino event could intensify into a 'super' episode, likely peaking between late 2026 and early 2027 — with immediate consequences including below-normal monsoon rainfall, heightened agricultural stress, and strain on the country's electricity grid. The warning comes as the India Meteorological Department (IMD) has already forecast below-normal rainfall for July, at less than 94 per cent of the Long Period Average (LPA) of 280.4 mm.

What El Nino Is and Why This One Is Different

El Nino is a climatic phenomenon marked by unusual warming of surface waters in the central and eastern tropical Pacific Ocean, disrupting weather patterns worldwide. It is formally declared when sea surface temperatures in the central and eastern Pacific rise at least 0.5 degrees Celsius above average across five consecutive overlapping three-month periods, accompanied by a weakening of easterly trade winds and shifts in tropical rainfall.

A 'super' El Nino — defined by sea surface temperature anomalies exceeding 2 degrees Celsius in the reference Nino region — is rare and historically associated with widespread global disruption. Scientists have warned that the 2026 event could rank among the strongest on record, placing it in the same category as the extreme episodes of 1997–98 and 2015–16.

Monsoon Outlook and Agricultural Pressure

The IMD has forecast below-normal rainfall across most of India in July, with exceptions in parts of northwest and northeast India, east-central India, and the eastern peninsular region, where normal to above-normal rainfall is expected. Maximum and minimum temperatures are projected to remain above normal across most regions.

July is the critical month for kharif sowing and reservoir recharge. States under close watch include Madhya Pradesh, Maharashtra, Chhattisgarh, parts of Gujarat, and adjoining Deccan districts, as well as Uttar Pradesh, Rajasthan, Karnataka, Bihar, Jharkhand, Telangana, Andhra Pradesh, Punjab, West Bengal, and Odisha.

Agriculture Minister Shivraj Singh Chouhan said on Wednesday that the government has put in place an extensive monitoring mechanism and expressed confidence that rainfall would strengthen further during July, accelerating kharif sowing. He noted that after a 33 per cent rainfall deficit in June, the overall deficit had narrowed to 24 per cent in July. The number of rainfall-deficient districts has also fallen from 262 to 178 in recent days.

Power Sector Faces Unprecedented Stress

A recent report by the Centre for Research on Energy and Clean Air (CREA) warned that India's power sector could face a greater impact from El Nino than any other country. Reduced rainfall weakens hydropower output, while lower wind speeds cut wind power generation — even as rising temperatures push up electricity demand for cooling. In conditions of reduced rainfall and weaker winds, the strain on thermal generation and transmission infrastructure is expected to intensify.

A high-level review meeting on Tuesday, chaired by Principal Secretary to the Prime Minister P.K. Mishra, assessed preparedness for the kharif season and El Nino's potential impact across sectors of the economy. He directed that the El Nino situation be monitored continuously and that the impact of a weak or delayed monsoon on vulnerable districts be assessed in coordination with state governments, so that timely remedial measures could be taken.

Marine and Coastal Risks on India's Horizon

The Indian National Centre for Ocean Information Services (INCOIS) began issuing specialised El Nino bulletins in late June, highlighting likely impacts on maritime sectors. According to INCOIS, the El Nino event is expected to peak during the winter season between November 2026 and January 2027, with sea surface temperatures in the Indian Ocean remaining above normal until April–May 2027.

The marine ecosystem across the northern Indian Ocean — encompassing both the Arabian Sea and the Bay of Bengal — is likely to face thermal stress between March and May 2027. This could trigger increased coral bleaching, more frequent marine heatwaves, and reduced catches of species such as sardine and mackerel due to fish migration or lower recruitment. INCOIS also warned that the Bay of Bengal is likely to remain rough during the monsoon season, raising the risk of coastal erosion and flooding along India's east coast.

What Happens Next

Agriculture Minister Chouhan has directed that contingency plans be activated at the district level, factoring in local water availability, crop patterns, seed stocks, sowing progress, and rainfall intervals. With the monsoon's performance over the coming weeks critical to both food security and reservoir levels, the government's response framework will be tested in real time as the season progresses.
