NOAA Warns Strong El Niño Likely in 2026, Threatening Global Weather and Crops

NOAA Warns Strong El Niño Likely in 2026, Threatening Global Weather and Crops
View gallery

A rapidly warming Pacific Ocean has pushed global agencies to raise the alarm over a fast‑forming El Niño that could reach “very strong” levels by late 2026, with NOAA now putting the chance of development at 82% for May–July and nearly certain odds that it will persist into next winter weather +1. Scientists warn the event could help propel 2026 into the ranks of the hottest years ever recorded and reshape rainfall, drought and storm patterns worldwide noaa +1.

How strong could this El Niño get — and how sure are scientists?

Forecast centers including NOAA’s Climate Prediction Center, the World Meteorological Organization (WMO) and the International Research Institute at Columbia University now broadly agree that neutral conditions in the tropical Pacific are giving way to El Niño, with probabilities above 70% for onset by early summer and model ensembles clustering in the “strong” range for sea‑surface temperature anomalies later in the year livescience +2. Some seasonal models used by the European Centre for Medium‑Range Weather Forecasts (ECMWF) even show scenarios exceeding 3°C of warming in the key Niño 3.4 region — territory associated in past decades with only a handful of record‑breaking “super” events usatoday +1.

The WMO said in an April update that “an El Niño event is expected to develop from mid‑2026,” adding that many models point to a strong episode, though it cautioned that the spring forecasting window still carries unusually high uncertainty bbc. ECMWF echoed that warning, noting that while ensemble guidance leans toward a powerful event, spread among model runs remains wide and confidence in precise strength will only solidify after late May usatoday.

Heat, floods, droughts and food prices: where the risks are rising

Because El Niño adds a short‑term boost to an already warmed climate, several analyses now project that the developing event could help make 2026 one of the top two hottest years on record, with monthly and regional extremes likely across many continents noaa +1. Typical El Niño patterns — and early signals in current seasonal outlooks — suggest increased rainfall and flood risk in parts of southern South America and the southern United States, alongside heightened chances of drought and wildfire in Australia, Indonesia, parts of Southeast Asia and the Caribbean bbc +1.

In agriculture, Europe’s Joint Research Centre has issued “widespread forecast warnings” for crop stress in the second half of 2026, highlighting vulnerabilities in southern Africa, Latin America and South and Southeast Asia as rainfall patterns shift wmo. The UN Food and Agriculture Organization’s global Food Price Index has already risen for three consecutive months, reaching 130.7 points in April, and economists at the World Bank say a strong El Niño now represents a clear upside risk to earlier expectations that agricultural prices would ease slightly this year watchers +1. While Atlantic hurricanes may be suppressed by increased wind shear, forecasters expect more active storm seasons in the eastern and central Pacific, raising risks for Mexico and parts of Central America drought +1.

The Bigger Picture

The emerging El Niño is unfolding against oceans that are already near record heat, amplifying concern that even a “typical” event could drive outsized impacts on weather, food security and disaster risk in 2026 noaa +1. Forecasters stress that exact strength and regional outcomes are not yet locked in, but humanitarian and agricultural agencies are urging governments to use the current lead time to pre‑position aid, adjust planting decisions and shore up social safety nets in likely hotspots bbc +2. As model confidence firms over the next two months, the world will learn whether this El Niño merely adds to a string of record‑warm years — or joins the short list of truly historic climate shocks.
