“Super El Niño” Could Bring Extreme Weather and Record Heat Worldwide

A potentially powerful El Niño is developing in the Pacific Ocean — and experts say it could have major impacts on weather across the globe.

Forecasters are warning this event could become a “Super El Niño,” a rare and particularly intense version of the climate pattern driven by unusually warm ocean temperatures near the equator.

If it strengthens as expected later this year, the system could shift weather patterns worldwide — bringing flooding to some regions and drought and wildfire risks to others.

In the United States, El Niño often brings stronger winter storms to parts of California and the southern tier of the country, increasing the risk of heavy rain and flooding. At the same time, it can suppress Atlantic hurricane activity by increasing wind shear that disrupts developing storms.

Globally, the impacts can be even more widespread. El Niño is linked to heat waves, drought conditions in places like Australia and parts of South America, and heavier rainfall in regions such as southeastern South America and parts of Africa and Asia.

Beyond immediate weather effects, a strong El Niño can also accelerate global warming. By releasing heat stored in the oceans into the atmosphere, it can push global temperatures even higher — raising the possibility that 2026 or 2027 could become the warmest years on record.

Scientists say while there is still some uncertainty about how strong this event will become, early indicators suggest it could be one of the most significant in decades.

Experts will continue monitoring ocean temperatures in the coming months to better understand how this developing El Niño could shape weather patterns around the world.
