Ocean temperatures are surging toward near-record highs this spring, setting the stage for what experts warn could be a rare and powerful super El Niño event later in 2026. Across the globe, scientists and meteorologists are keeping a close eye on the Pacific, where the transition from a cooling La Niña to neutral conditions is already underway, and all signs point to a significant shift in the world’s climate patterns in the coming months.
Report ocean temperatures are nearing record highs this spring, indicating a potential super El Niño event developing later in 2026.
Highlight NOAA forecasts predicting up to a 25% chance of super El Niño emergence by fall or early winter, driven by strong westerly wind bursts.
According to the European Union’s Copernicus Climate Change Service, March 2026 saw ocean temperatures approach the highest ever recorded for that month, just shy of the 2024 peak that was driven by El Niño conditions. The Copernicus team observed, “Current records reflect once again a likely transition toward El Niño conditions.” Their assessment echoes a recent forecast by the World Meteorological Organization (WMO), which predicted that the cooling La Niña phase would soon give way to neutral conditions, before swinging into El Niño later this year.
In the United States, the heat has been particularly striking. Federal weather data revealed that March 2026 was the most abnormally hot month in 132 years of records. Meteorologist Shel Winkley of Climate Central told the Associated Press, “One reason that’s so concerning is just the sheer volume of records. This is coming on the heels of what was the worst snow year. And the hottest winter of record.” On March 20 and 21, about one-third of the US experienced unseasonable heat that Climate Central calculated would have been virtually impossible without human-caused climate change.
These extreme temperatures are not isolated events. Since the pre-industrial era, the global surface air temperature has increased by between 1.3°C and 1.4°C, according to Copernicus. In the Arctic, the situation is even more dire: the extent of sea ice in March was 5.7% below average, the lowest on record for that month. The area of ocean covered by ice continues to shrink year after year, a stark indicator of rapid warming in both the Arctic and Antarctic regions.
But what exactly is a super El Niño, and why does it matter? El Niño is a periodic warming of water in the central and eastern equatorial Pacific Ocean, part of a natural cycle known as the El Niño/Southern Oscillation (ENSO). This cycle, which alternates between the warm El Niño phase and the cool La Niña phase, causes short-term swings in global temperatures and has major impacts on weather patterns worldwide.
NOAA’s latest computer model forecasts, released in April 2026, predict a 61% chance that El Niño will develop between May and July. There’s an estimated 50% chance that this El Niño will be strong, with ocean surface temperatures at least 1.5°C above average, and a 25% chance it could intensify into a super El Niño by fall or early winter—meaning those warm anomalies could reach 2°C or more. Only five super El Niños have been recorded since 1950, the last occurring in 2015-16. These rare events have a track record of upending global weather, and the coming months could see dramatic shifts.
One factor heightening scientists’ confidence in a looming super El Niño is a powerful burst of westerly winds across the equatorial Pacific. Paul Roundy, an El Niño expert from the University of Albany, explained to weather.com, “These periods of strong winds blowing west to east are pushing warm waters onto the equator and driving them eastward, contributing to rapid warming in the eastern Pacific.” Roundy added that the westerly wind burst in early April 2026 is likely the strongest in over 50 years, perhaps even the last century. This surge may overcome the so-called “spring predictability barrier” that usually makes long-range forecasts tricky.
What does all this mean for the world’s weather in 2026 and beyond? For starters, a strong El Niño typically brings wetter winters to the southern United States, from California to Florida, as the southern jet stream is energized and storm tracks are amplified. This can result in more snow if temperatures are cold enough, while the northern US—stretching from the Northwest through the northern Rockies and into the Midwest—often experiences milder and drier winters.
There are also far-reaching effects outside the US. El Niño tends to cause drier conditions in parts of Africa, India, Australia, the Philippines, Indonesia, the Caribbean, and northern South America, while parts of Ecuador, Peru, eastern Africa, central Asia, Chile, Uruguay, and Paraguay usually see wetter than average conditions. These shifts can have profound impacts on agriculture, water resources, and even the risk of wildfires and flooding.
Hurricane season is another area where El Niño’s influence is keenly felt. Stronger El Niño events generally suppress hurricane activity in the Atlantic by producing more sinking air and stronger wind shear, both hostile to hurricane formation. However, the opposite tends to happen in the eastern and central Pacific, where hurricane seasons can become more active during strong El Niños. That said, as the 2023 season proved, there’s always room for surprises.
In Colorado and the broader US West, the prospect of a super El Niño is raising hopes that it could bring relief to historic drought conditions. Previous super El Niño years—such as 1982-83, 1997-98, and 2015-16—have brought above-average precipitation and snow to Colorado, helping to replenish snowpack and reservoirs. Peter Goble, assistant state climatologist at the Colorado Climate Center, cautions that while there is a correlation between super El Niño conditions and increased precipitation, “It’s a small enough sample not to get too excited, but it’s in really good company.”
Colorado’s water situation remains precarious. As of early April, the state’s snowpack was only 22% of normal, with the South Platte Basin—serving cities like Fort Collins and Boulder—at 32%. Reservoirs are around 80% of normal, and nearly the entire state is experiencing some degree of drought. Still, Goble notes that “one banner year can undo the damage of a low snowpack year,” expressing cautious optimism that a super El Niño could turn things around.
The broader environmental stakes are high. Oceans act as the planet’s heat reservoirs, absorbing most of the excess warmth generated by human activities. When oceans heat up, they expand, contributing to rising sea levels. Warmer seas also accelerate the melting of polar ice and fuel stronger storms and heavier rainfall, both of which have become more frequent in recent years.
Perhaps most concerning is the link between super El Niño events and global temperature spikes. The super El Niños of 2015 and 2016 shattered previous heat records, and all of the planet’s top 10 warmest years have occurred since 2015. With 2026 already shaping up as a record-breaker, scientists warn that new temperature highs are likely, possibly extending into 2027. A December 2025 study found that super El Niño events can drive sudden “climate regime shifts” in both temperatures and precipitation, an effect that may be intensifying as the world warms.
As the Pacific continues to heat up and the odds of a super El Niño grow, communities, farmers, water managers, and policymakers around the world are bracing for a season of potential extremes—hoping for relief in some places, but wary of the disruptions that such a powerful climate event can bring.
With history as a guide and the latest science as a warning, the world waits to see just how much the coming super El Niño will reshape our weather, our environment, and our daily lives.
