Core Forecast: Historic El Niño Likely This Fall-Winter
The U.S. Climate Prediction Center (CPC) indicated a greater-than-90 % chance of a very strong El Niño during the Northern Hemisphere fall and winter of 2026-27. NOAA’s September 10 assessment gave a 75 % chance the event will exceed the strength of all El Niño episodes recorded since 1950. The World Meteorological Organization (WMO) forecasts a near-100 % likelihood that the El Niño will persist through February 2027, describing it as “exceptional.”
Background & Context
El Niño is the warm phase of a natural climate oscillation that recurs every two to seven years, marked by weakened trade winds and elevated sea-surface temperatures across the central and eastern equatorial Pacific. Recent paleoclimate research from the Galápagos Islands shows El Niño temperature swings have intensified by roughly 36 % over the past four decades, a trend attributed to anthropogenic warming. Satellite observations in June 2026 recorded tropical Pacific sea-surface temperatures more than 10 °C above long-term averages.
Data & Statistics
- Probability estimates: >90 % (CPC), 75 % (NOAA, September 10), near-100 % (WMO).
- Sea-surface temperature anomaly: >10 °C above average in parts of the tropical Pacific.
- Agricultural impact: Oxfam reports drought linked to El Niño has already ruined bean and corn crops across Central America’s Dry Corridor, deepening food and water insecurity.
- U.S. wheat outlook: NOAA forecasters anticipate increased rainfall later in the fall and winter across the central and southern Plains, potentially improving winter wheat yields.
- Pakistan’s economy: Agriculture accounts for roughly 20 % of GDP; drought-prone provinces such as Sindh and Balochistan face threats to wheat, cotton, and rice production.
Official Statements & Responses
- Donald Keeney, agricultural meteorologist at Vaisala Weather (Finland), highlighted ongoing drier conditions across Central America and projected additional warming before a gradual decline later in winter and spring.
Impact on Vulnerable Regions
- Central America: Persistent drought threatens staple crops, exacerbating food insecurity for millions.
- United States: Anticipated increased precipitation may benefit winter wheat in the Plains, while other regions could experience heightened heat stress.
- Pakistan: A stronger El Niño is expected to weaken monsoon rains in Punjab and Khyber Pakhtunkhwa, intensify drought in Sindh and Balochistan, and raise the risk of heat waves and glacial-lake outburst floods in Kashmir and Gilgit-Baltistan. The cumulative effect threatens agricultural output, hydropower generation, and urban heat exposure for cities such as Karachi and Lahore.
On-the-Ground Reports
Oxfam’s field assessments in the Central American Dry Corridor document crop failures and deteriorating water supplies linked to El Niño-driven drought. Local meteorological agencies in Pakistan have begun issuing early warnings, but relief efforts remain largely reactive.
Conflicting Reports & Gaps
- Probability variance: CPC’s >90 % estimate, NOAA’s 75 % figure, and WMO’s near-100 % projection differ, reflecting methodological uncertainties.
- Impact specificity: Global agencies outline broad risk categories, but detailed, region-specific impact models—particularly for Pakistan’s complex topography—are lacking.
- Preparedness data: No comprehensive, publicly available assessment quantifies the readiness of national disaster-management systems in the most vulnerable countries.
What’s Next
Forecasts from the CPC, NOAA, and WMO will continue to be updated through February 2027. The WMO has announced a coordinated “exceptional preparation” campaign with national meteorological services, urging governments to accelerate climate-smart agricultural policies, expand water-storage infrastructure, and strengthen early-warning systems ahead of the anticipated peak of the El Niño event.
