El Niño 2026: UN Warning and India’s Risk
Why in News?
- On 22 October 2026, the United Nations warned from Geneva that a powerful El Niño could cause major economic shocks across Latin America, Africa, Asia and the Pacific, News On AIR reported.
- UN humanitarian chief Tom Fletcher called it a "wrecking ball" and said the next two weeks are critical for preparedness.
- World Meteorological Organization Secretary-General Celeste Saulo said the event could reach unprecedented strength toward the end of 2026.
- It follows the WMO update of 8 October 2026, which said El Niño is firmly established.
Key Terminologies
- El Niño
- A natural climate pattern in which surface waters of the central and eastern tropical Pacific become warmer than normal, which shifts rainfall and temperature patterns across the world.
- Niño 3.4 Index
- The sea-surface temperature anomaly in a central Pacific box, used to measure the strength of El Niño. A larger positive value means a stronger event.
- Indian Ocean Dipole
- A difference in sea-surface temperature between the western and eastern Indian Ocean. A positive phase brings more rain to the west and can offset El Niño's drying effect on the Indian monsoon.
- Long Period Average
- The average monsoon rainfall over 1971 to 2020, about 87 cm for India as a whole, against which the India Meteorological Department measures each season.
Key Issues
- Record Strength: WMO said on 8 October 2026 that the Niño 3.4 anomaly was +2.5 °C in August 2026 and is forecast near +3.7 °C for October to December, above the previous record of +2.6 °C in November 2015 to January 2016.
- Persistence: WMO forecasts a near-100 per cent chance that El Niño continues through February 2027, with a peak around December 2026, according to a consensus of thirteen national and international centres.
- Humanitarian Risk: Tom Fletcher said on 22 October 2026 that about 50 million people could face increased hunger, and the African Development Bank estimates African costs of US$ 10 billion to 20 billion, with GDP falling 1 to 2 per cent.
- Monsoon Damage: India received 706.9 mm of rain from 1 June to 22 September 2026 against a normal 832.4 mm, a 15 per cent deficit, and IIT Gandhinagar's India Drought Monitor showed 52.5 per cent of the country dry or in drought on 16 September.
- Kharif Stress: The area under kharif crops stood at 1,096.49 lakh hectares on 11 September, down 16.05 lakh hectares from a year earlier, Down To Earth reported on 23 September 2026.
Key Implications
Positive/Pros/Merits
- Early Warning Lead: WMO's monthly Global Seasonal Climate Update gives governments weeks of lead time, and Fletcher urged countries to place disaster response capacity on standby.
- Indian Ocean Support: WMO expects a positive Indian Ocean Dipole of about +0.5 °C in October to December, which can partly offset El Niño's drying effect on the monsoon region.
- Targeted Preparedness: The agriculture ministry and ICAR identified 315 districts as vulnerable to El Niño-related farm distress in June 2026, with 111 in a high-priority category.
- Regional Partnership: The India-UN Development Partnership Fund has funded early warning and disaster risk reduction projects in seven Pacific Island countries, The Tribune noted on 22 October 2026.
Negative/Cons/Demerits
- Food And Price Pressure: A deficient monsoon of 15 per cent and lower kharif sowing raise the risk of higher food prices, an analytical link from the figures reported.
- Unequal Regional Impact: The seasonal deficit was 43 per cent in Rayalaseema, 37 per cent in coastal Andhra Pradesh and 36 per cent in Marathwada, so distress is concentrated in some farm regions.
- Regional Spillover: Saulo warned of higher temperatures, less rain and more wildfire smoke in Southeast Asia, which strains water and farming.
- Forecast Limits: IMD forecast 90 per cent of the Long Period Average on 29 May 2026, with a margin of plus or minus 4 per cent, but the deficit by 22 September was 15 per cent.
Key Initiatives
- World Meteorological Organization, 2026: Its monthly Global Seasonal Climate Update of October 2026 said El Niño is firmly established using a consensus of thirteen centres.
- United Nations: Under-Secretary-General Tom Fletcher on 22 October 2026 asked governments, businesses and partners to mobilise resources and keep response capacity on standby.
- Ministry of Agriculture and ICAR, June 2026: They identified 315 districts as potentially vulnerable to El Niño-related farm distress and placed 111 in a high-priority category.
- India Meteorological Department, 2026: It gave a seasonal outlook of 90 per cent of the Long Period Average on 29 May 2026 and expected weak El Niño conditions to strengthen later in the season.
- India-UN Development Partnership Fund: It supports early warning and disaster risk reduction projects in seven Pacific Island countries, and the Quad runs Humanitarian Assistance and Disaster Relief programmes in the Indo-Pacific.
The UN and WMO say the next weeks are the window to prepare, with response capacity placed on standby and resources mobilised. In India, the agriculture ministry and ICAR have listed vulnerable districts, and IMD continues to issue seasonal outlooks.
Director's Perspective
Way Forward
- Link IMD's seasonal outlook to district-level advisories for sowing, water and credit, so the 315 vulnerable districts get early support.
- Review reservoir stocks and rabi water plans now, especially in the Deccan and the south.
- Strengthen crop insurance claims and food-stock management before prices rise, so deficits do not turn into inflation.
- Share early-warning tools with neighbours and Pacific partners through existing funds.
The 2026 El Niño is a test of preparedness more than prediction, because the forecast is clear while its impact on India is already visible. Strengths are early warning and district listing, while weaknesses are uneven regional preparedness and limits in seasonal forecasting. In a Mains answer, explain the El Niño-monsoon link with the Indian Ocean Dipole, then conclude that district-level planning for water, crops and prices is the best defence.

Frequently Asked Questions
What is El Niño and why is the October 2026 warning important?
El Niño is a warming of the central and eastern tropical Pacific that changes rainfall and temperature worldwide. On 22 October 2026 the United Nations warned it could cause major economic shocks, and WMO said on 8 October that it could be among the strongest since at least 1950.
How does El Niño affect the Indian monsoon?
El Niño usually weakens the Indian southwest monsoon, and a positive Indian Ocean Dipole can partly offset it. In 2026, India had a 15 per cent rain deficit between 1 June and 22 September, according to the India Meteorological Department data reported by Down To Earth.
What did the World Meteorological Organization forecast on 8 October 2026?
WMO said El Niño is firmly established and strengthening rapidly, with a near-100 per cent chance of persisting through February 2027 and a peak around December 2026. It forecast a Niño 3.4 anomaly near 3.7 degrees Celsius for October to December, a record.
PYQ Practice — Statement Analysis
1 A positive Indian Ocean Dipole can partly offset the drying effect of El Niño on the Indian monsoon.
A positive phase brings more rainfall to the western Indian Ocean region and the Indian subcontinent.
2 El Niño is a cooling of the surface waters of the central and eastern tropical Pacific.
El Niño is a warming of those waters, while La Niña is the cooling phase.
3 The India Meteorological Department measures monsoon rainfall against the Long Period Average of 1971 to 2020.
The average is about 87 cm for the country as a whole.
