Super El Niño Could Deliver Record Global Heat and Extreme Weather by Fall 2026

Amsterdam, Wednesday, 11 March 2026.
Climate models now show an 80% chance of a strong El Niño event developing by August 2026, with some forecasters predicting a ‘Super El Niño’ that could rival the most powerful on record. This weather phenomenon, characterized by Pacific Ocean temperatures rising at least 2.0°C above normal, would likely push 2026 and 2027 into the top three hottest years ever recorded globally. The developing pattern promises to reshape weather worldwide: wetter conditions across the southern United States and Gulf Coast, milder winters in northern regions, and potentially the quietest Atlantic hurricane season since 2015. For Europe, including the Netherlands, the correlation remains weaker but suggests increased chances of above-normal temperatures and altered precipitation patterns throughout the region.

Computer Models Signal Dramatic Pacific Shift

The evidence for a developing Super El Niño continues to mount as computer models project a fundamental shift in Pacific trade winds over the coming months [1]. As of March 9, 2026, unusually warm water is spreading beneath the Pacific Ocean surface, a key precursor to El Niño formation [1]. While the atmospheric circulation still reflects the influence of a weak La Niña, the ocean is beginning to display more El Niño-like characteristics [1]. The European Centre for Medium-Range Weather Forecasts (ECMWF) models now suggest a 98% chance of a moderate El Niño event by August 2026, with an 80% chance of a strong event and a 22% chance of a super event [2]. These projections represent a significant escalation from NOAA’s March 3, 2026 outlook, which noted model uncertainty for late summer and beyond while expecting the current La Niña phase to wane and enter a neutral phase with a 60% chance from February through April [2].

From ‘Super’ to ‘Godzilla’: Meteorologists Upgrade Predictions

Some weather forecasters have begun using even more dramatic terminology to describe the potential event. David Schlotthauer, a professional weather forecaster, has upgraded his prediction from a ‘super’ El Niño to a ‘Godzilla’ El Niño [5]. According to Schlotthauer’s analysis, “The latest oceanic and atmospheric signals continue to show a rapidly strengthening El Niño pattern developing for Fall 2026, and some forecast guidance suggests this event could become exceptionally strong if current warming trends continue” [5]. Colin McCarthy, posting on Instagram as @us_stormwatch on March 5, 2026, stated that “Everything we’re seeing suggests a very strong El Niño will develop later this year and some climate models are showing the potential for a super El Niño” [4]. McCarthy emphasized that the forecasted pattern “is shaping up to be far more significant than the last strong El Niño in 2023” [4].

Global Temperature Records at Risk

The implications for global temperatures are profound. Climate experts predict that 2026 and 2027 will “almost certainly rank among the top 3 hottest years ever recorded globally” if the Super El Niño materializes [4]. This projection stems from the fundamental mechanics of El Niño events, which tend to boost global average surface temperatures [1]. Yu Kosaka, a climate scientist at the University of Tokyo, explains the underlying process: “During La Niña, warm water sticks to a deeper depth, resulting in a cooler surface. And that reduces how much energy goes out into space” [2]. Tom Di Liberto, a former NOAA meteorologist now at Climate Central, noted that transitioning from La Niña to El Niño releases heat [2]. The potential for record-breaking temperatures becomes even more significant when considering that a strong El Niño would likely result in record global temperatures [1].

Regional Weather Impacts Across Continents

The developing Super El Niño promises to reshape weather patterns across multiple regions. For the United States, the phenomenon typically brings increased rain and flooding across the Gulf Coast and Southeast, while creating hotter, drier conditions in the northern states and Canada during winter [2]. Brian James, Nexstar’s chief meteorologist, explains that “the exact regional impacts will depend on how strong the event becomes and how quickly it develops, but a transition toward El Niño generally tilts the odds toward a wetter southern U.S. and milder conditions across parts of the northern states heading into winter” [2]. The Atlantic hurricane season could see dramatic changes, with Andy Hazelton, an associate scientist at the University of Miami CIMAS, posting on social media that “confidence is growing that this might be the quietest season since 2015, unless something very unusual happens” [2]. This reduction occurs because El Niño suppresses vertical wind shear and stabilizes the atmosphere, reducing hurricane formation [2].

Netherlands Faces Uncertain Weather Outlook

For the Netherlands and broader European region, the connection to El Niño remains more complex and less predictable. Dutch meteorological service KNMI has emphasized for years that the correlation between El Niño and Dutch summer weather is weak, with the Atlantic Ocean typically serving as the dominant factor in Netherlands summers [8]. However, historical analysis suggests that El Niño summers in Europe show a slightly greater chance of above-normal temperatures, more high-pressure influence in Western Europe, and more frequent dry episodes in Southern Europe during summer months, with wetter conditions typically occurring in winter [8]. The latest long-term models, including those from the ECMWF, show a cautious warming signal for Northwest Europe for the coming summer, though no clear signal emerges for precipitation patterns [8]. Dutch forecasters expect stronger summer signals to emerge in seasonal forecasts at the end of April 2026, with the definitive summer forecast scheduled for late May 2026 as weather patterns solidify during June [8].
