Meteorologists are closely monitoring the development of a potential “super El Niño” later this year, and some forecasts suggest it could become one of the strongest on record. According to a recent report from The Weather Channel, warming ocean temperatures in the equatorial Pacific are increasing the likelihood of a major El Niño event developing by late 2026.
El Niño is a climate pattern that occurs when sea surface temperatures in the central and eastern Pacific Ocean become warmer than average for an extended period. A “super El Niño” refers to especially intense warming — typically when temperatures rise at least 2 degrees Celsius above normal.
These stronger events are relatively rare. Since 1950, only a handful of super El Niño events have been recorded, including the well-known 1997-98 and 2015-16 events.
Wetter Conditions in Some Areas, Drier Conditions in Others
While every El Niño event behaves differently, stronger systems often produce noticeable shifts in weather patterns across the globe.
The Weather Channel reports that wetter winter conditions are commonly seen across parts of the southern United States, including California, the Southwest, and the Gulf Coast during strong El Niño years. Increased rainfall can raise the risk of flooding, mudslides, and severe storms in some regions.
Meanwhile, northern parts of the U.S. often experience milder and drier winter conditions during El Niño events.
Globally, El Niño can also influence rainfall patterns in regions such as Africa, South America, Australia, and Southeast Asia. Some areas may experience heavier rain and flooding, while others could face drought conditions.
Hurricane Seasons Could Shift
El Niño may also affect tropical storm activity.
According to The Weather Channel, stronger El Niño conditions typically increase wind shear across parts of the Atlantic Ocean, which can make it harder for hurricanes to form and strengthen. As a result, Atlantic hurricane seasons are often quieter during strong El Niño years.
At the same time, hurricane activity in the eastern and central Pacific Ocean often becomes more active.
Rising Global Temperatures Remain a Concern
One of the most closely watched effects of a super El Niño is its impact on global temperatures. The Weather Channel notes that these events often contribute to significant temperature spikes worldwide as additional heat from the Pacific Ocean is released into the atmosphere.
The previous super El Niño in 2015-16 coincided with record global warmth, and experts suggest another strong event could contribute to additional temperature records in the coming years.
As scientists continue monitoring ocean and atmospheric conditions, forecasts may evolve. Still, growing confidence in a potential super El Niño means weather experts around the world will be watching closely in the months ahead.
