A rare climate event may be quietly taking shape beneath the Pacific Ocean, with the potential to reshape weather patterns across the globe. Early forecasts suggest the next El Niño could be far stronger than usual, raising the prospect of extreme conditions in the months ahead—though for now, scientists remain cautious.
Super El Niño Forecast Gains Attention Among Climate Experts
New modelling from international agencies indicates that an El Niño event could develop within months—and it may be stronger than initially expected. The European Centre for Medium-Range Weather Forecasts projects sea surface temperatures rising between 1.3°C and 3.1°C above average. If temperatures exceed 2°C, the event would be classified as a “super El Niño”, a rare and more intense version of the climate pattern.
These events are uncommon, typically occurring every 10 to 15 years. Australia has experienced only three such events since 1982, with the most recent in 2015.
El Niño Impact Could Bring Drier and Hotter Conditions to Australia
A strong El Niño is generally associated with warmer and drier conditions across large parts of Australia. This can increase the risk of heatwaves, drought and bushfires, particularly in eastern regions. The Bureau of Meteorology is already forecasting above-average sea temperatures in eastern and southern waters in the coming months, including up to 3°C higher than normal in parts of the Tasman Sea.
Still, El Niño does not act alone. Weather systems such as cyclones and regional patterns can influence outcomes, sometimes offsetting expected dryness.
Global Models Signal Growing Probability of Strong Event
The US National Oceanic and Atmospheric Administration (NOAA) estimates there is a one-in-three chance the developing El Niño could become strong by late 2026. Several indicators support this outlook, including warming subsurface ocean temperatures and weakening trade winds—both key signals in the formation of El Niño conditions.
At the same time, the current La Niña phase is fading, clearing the way for a transition. Most models agree that a shift toward El Niño is likely by winter, though timing varies from May to late winter.
Uncertainty Remains Around Strength of Super El Niño
Despite the growing signals, scientists remain cautious. Climate expert Ailie Gallant highlights the so-called “autumn predictability barrier”, a period when forecasts are less reliable, reports 9News. This means that while the trend points toward warming in the central and eastern Pacific, it is still too early to confirm whether the event will reach “super” levels.
In practical terms, clearer answers are expected around June, when models become more stable.
A Climate Pattern With Global Consequences
El Niño is part of a broader cycle known as the El Niño–Southern Oscillation, which influences weather patterns worldwide every few years. While it often brings drier conditions to Australia, its global effects can include flooding, heat extremes and agricultural disruption in other regions.
For now, the outlook remains uncertain—but the possibility of a super El Niño is enough to place scientists and policymakers on alert, as the months ahead could shape weather patterns on a global scale.
