Odds are increasing for a historically strong Super El Niño emerging from the Pacific Ocean, threatening to exacerbate global warming and disrupt weather patterns worldwide by fall.
El Niño is emerging in the Pacific Ocean faster than anticipated, with odds increasing that it could become a historically strong "Super" event by fall or winter. According to a recent update from NOAA’s Climate Prediction Center, there is a two-in-three chance that the phenomenon's peak strength will be strong or very strong.
This rapid development marks a significant shift from last month’s forecast, which favored neutral conditions through June. The boost in confidence stems from a vast pool of warm water building in the central and eastern equatorial Pacific, which is expected to rise to the surface and sustain the warming trend. While the exact peak strength remains uncertain, the likelihood of it reaching super-status has grown from one in four to about one in three.
As a natural climate cycle, El Niño occurs when tropical Pacific waters warm sufficiently to shift atmospheric wind patterns, creating ripple effects on weather globally. These conditions can fuel droughts, heatwaves, and wildfire risks in some regions while causing flooding in others. Crucially, a stronger El Niño amplifies the effects of human-caused global warming, making it more likely that 2026 or 2027 will become the warmest years on record.
El Niño typically occurs every two to seven years and lasts between nine and twelve months. Its intensity is measured by how much water temperatures exceed the average in the equatorial Pacific. Weak El Niño conditions begin when temperatures rise above 0.5 degrees Celsius above average for an extended period. To be classified as a very strong or Super El Niño, water temperatures must exceed 2 degrees Celsius above average.
Currently, average water temperatures are just below the 0.5-degree threshold but are expected to climb above it by next month. The Climate Prediction Center notes that the chances of El Niño lasting through winter have increased to 96%, a near certainty. This prediction is bolstered by computer models showing this potential event could be the strongest on record, dating back to 1950.
Michelle L’Heureux, the scientist leading El Niño and La Niña forecasting at the CPC, explained that a stronger event is more likely if atmospheric changes continue to sync with ocean temperature rises this summer. Specifically, if winds near the equator weaken as ocean temperatures rise, the conditions for a super event are met.
The last Super El Niño occurred in 2015-2016, which remains the strongest in NOAA records. Other notable strong events include those in 1997-1998, 1982-1983, and 1972-1973. While a super event is possible, even a standard strong El Niño will likely pack a significant punch in affecting global weather, though impacts can vary. For instance, the 2015-2016 event caused serious drought in the Caribbean but failed to produce the expected wetter winter in Southern California.
The arrival of a strong or super El Niño will likely alter weather patterns significantly into early 2027. One of the most notable impacts is on the Atlantic hurricane season. Stronger El Niños often create storm-killing conditions in the Caribbean and tropical Atlantic, resulting in fewer tropical storms and hurricanes in those regions.
Conversely, hurricane season typically becomes busier in the central and eastern Pacific Ocean. This shift could mean increased tropical threats to Hawaii and the Southwest United States, depending on the specific tracks of these storms. Forecasters must closely monitor where these storms track to provide accurate warnings for vulnerable coastal areas.
In the United States, the biggest impacts are expected during the winter months. A warmer-than-average winter is typical from the northern US to western Canada and Alaska, although harsh cold spells can still occur. Meanwhile, the southern tier of the US often becomes wetter and cooler, as the intensified jet stream steers more storm systems over this region.
While the exact magnitude of weather impacts remains unpredictable, the combination of a strong El Niño and existing climate trends raises the stakes for extreme weather events. The phenomenon is essentially "loading the dice" toward record-breaking heat, with NOAA already stating it is very likely that 2026 will be among the five warmest years on record, even before accounting for the additional warming effect of El Niño.
The emerging El Niño poses a critical test for climate resilience, with a high probability of intensifying global temperatures. If the event reaches super status, it will likely push global warming metrics to unprecedented levels, potentially making 2026 the hottest year in recorded history. This scenario underscores the urgent need for adaptive strategies in agriculture, water management, and disaster preparedness. As the warm water pool in the Pacific continues to expand, its influence on atmospheric circulation will dictate weather patterns worldwide, amplifying both drought and flood risks in vulnerable regions.
