In briefCurrent forecasts suggest El Ni\u00f1o or strong El Ni\u00f1o conditions could form later this year.A climate scientist noted forecasts are unreliable at this time of year, while another expert says current models only show one piece of the puzzle.<\/p>\n

A strong or so-called “super” El Ni\u00f1o could develop later this year, according to some climate forecasters and media reports, bringing the risk of more severe weather extremes and the possibility of a very hot year for the world in 2027. What is a “super El Ni\u00f1o” \u2014 and is it actually on the cards? <\/p>\n

The answer is nuanced, and experts say it’s still too early to know.<\/p>\n

In an X post, Washington Post meteorologist Ben Noll estimated a 22 per cent chance of a “super El Ni\u00f1o” by August and an 80 per cent chance of a “strong” one based on new modelling from the European Center for Medium-Range Weather Forecasts.<\/p>\n

The El Ni\u00f1o climate pattern, which is linked to Pacific Ocean temperatures and affects weather around the world in different ways, fuelled warm and dry conditions when it last occurred in Australia in 2023. <\/p>\n

It develops when sea surface temperatures in the central and eastern tropical Pacific Ocean are warmer than usual. <\/p>\n

Current forecasts suggest El Ni\u00f1o or strong El Ni\u00f1o conditions could form later this year, according to Andrew King, a climate scientist at the University of Melbourne. <\/p>\n

However, he noted forecasts are unreliable at this time of year, and he would not place any confidence in predictions until they come into sharper focus in May or June.<\/p>\n

“At this time of year, in our autumn, there’s kind of a bit of a reset” in conditions in the Pacific Ocean, he told SBS News. <\/p>\n

“Things die down a bit. There’s not really that much going on. And then something usually emerges, kind of late autumn, early winter.”<\/p>\n

“Super” El Ni\u00f1o is not a scientific term, but some use it to describe a very strong El Ni\u00f1o event.<\/p>\n

A spokesperson for the Bureau of Meteorology (BoM) told SBS News it isn’t forecasting a super El Ni\u00f1o and it does not use that term to categorise El Ni\u00f1o\u2013Southern Oscillation (ENSO) events.<\/p>\n

ENSO refers to the climate cycle involving fluctuations in ocean temperatures and atmospheric conditions across the tropical Pacific, driving shifts between El Ni\u00f1o, neutral and La Ni\u00f1a<\/a> phases.<\/p>\n

The BoM said all models indicate a return to neutral conditions in early autumn with a possible shift to El Ni\u00f1o by the end of winter.<\/p>\n

Linden Ashcroft, a senior lecturer in climate science at the University of Melbourne and a Climate Council fellow, said that while it’s “somewhat unusual to have so much agreement at this time of year” that an El Ni\u00f1o might occur, some models are missing important pieces of the puzzle at this stage.<\/p>\n

“The ocean is only part of the story,” she told SBS News.<\/p>\n

“El Ni\u00f1os are the ocean plus the atmosphere, and these forecasts are only really talking about the ocean right now.”<\/p>\n

The BoM noted that its long-range forecasts take into account all influences from the oceans and atmosphere.<\/p>\n

What happens in Australia during a strong El Ni\u00f1o?<\/p>\n

El Ni\u00f1o can drive certain patterns around the world, including wetter conditions and flooding in South America and drought in Australia and Asia. <\/p>\n

Typically, global temperatures increase during El Ni\u00f1o and fall during La Ni\u00f1a, the flip side of the pattern, which occurs when Pacific Ocean temperatures are cooler than usual. <\/p>\n

However, not every El Ni\u00f1o is the same, and the strength of the pattern doesn’t guarantee hot and dry weather.<\/p>\n

\"Record<\/p>\n

Record heat and extreme weather: Experts raise alarm on climate<\/p>\n

“In Australia, eastern Australia especially, El Ni\u00f1o springs and summers are more likely to be drier and hotter than normal,” King said.<\/p>\n

“But it’s not super strongly tied to how strong an El Ni\u00f1o is. There’s other things that influence our weather and climate as well, which means that even if we have quite a strong El Ni\u00f1o, that doesn’t guarantee a really dry spring or summer. It just raises the probability of it.”<\/p>\n

On average, El Ni\u00f1o episodes occur every three to five years, and typically last for about a year, but can be shorter or much longer, according to the Bureau.<\/p>\n

‘Lingering impacts’ of El Ni\u00f1o could bring ‘new record’ year in 2027<\/p>\n

Should an El Ni\u00f1o form this year, it would likely mean an increase in the global average temperature for 2027, King said. <\/p>\n

“If we did have an El Ni\u00f1o form, [there’s a] pretty good chance that 2027 would be a very hot year for the world. Possibly a new record hot year.”<\/p>\n

\"Climate<\/p>\n

Climate report warns of increasingly extreme weather<\/p>\n

Months of unusually high sea surface temperatures in the Pacific are “enough to have quite a big effect on the global average temperature that … would persist beyond 2026 and into 2027 also”. <\/p>\n

“It does kind of have lingering impacts due to relationships with other parts of the ocean and atmosphere as well,” he said.<\/p>\n

The hottest year on record<\/a>, 2024, was driven in part by a moderate-to-strong El Ni\u00f1o in 2023. <\/p>\n

In Australia, 2024 marked the second-hottest year for the country since records started in 1910, according to the Bureau of Meteorology. Australia’s hottest year on record was 2019, which ended with the catastrophic Black Summer bushfire season<\/a>.<\/p>\n

In the World Meteorological Organization’s State of the Global Climate report released earlier this week, it confirmed that the past 11 years have been the hottest on record. <\/p>\n

Climate change will likely drive new records every year, Ashcroft said. A global El Ni\u00f1o event would only “tip the scales even more”, she said.<\/p>\n

“That would lead to a very, very hot year for the planet,” she said.<\/p>\n

Australians warned ‘not to make big decisions’ just yet<\/p>\n

Ashcroft pointed out that in Australia, where “extreme climate is part of our identity”, people are very invested and well-versed in this particular climate pattern, which can evoke fears of bushfires, drought and intense heat for some, such as farmers.<\/p>\n

She noted that even if an El Ni\u00f1o event does occur, it doesn’t always lead to those outcomes, particularly as previously known patterns evolve due to climate change. <\/p>\n

“I’d be encouraging people not to make big decisions based on this one metric, particularly in Australia,” she said.<\/p>\n

“An El Ni\u00f1o event doesn’t always equal hot and dry. The relationships between El Ni\u00f1o and La Ni\u00f1a and Australian climate, they are changing in a warmer world, so the relationships that we understood in the past are not quite as reliable now.”<\/p>\n
