Ocean Indicators We’re Tracking for El Niño’s Arrival on the West Coast

September 5, 2026 — Has El Niño reached the West Coast?

You might think it has. After all, the ocean off Southern and Central California is unusually warm. But that is from a recent marine heatwave predates the current El Niño. Much of the Pacific Coast is experiencing relatively normal conditions while still awaiting the impacts of what could be a very strong El Niño.

In June, NOAA’s National Weather Service declared that El Niño had developed. That finding, however, is based on ocean temperatures from the tropical Pacific Ocean, near the Equator, which warm ahead of El Niño’s impact on the Americas.

While eastern tropical Pacific temperatures have already risen more than 2°C (about 3.6°F) above normal, El Niño-related warming along the West Coast typically lags that increase by a few months. NOAA Fisheries scientists are tracking West Coast conditions as part of our Integrated Ecosystem Assessment. Here are some of the changes in ocean conditions and marine life that typically signal the arrival of El Niño’s influence along the West Coast.

Two giant warming patterns are brewing in the Pacific and warping US weather

September 2, 2026 — In the north-east Pacific Ocean, an immense and persistent heatwave is wreaking havoc on marine life and weather patterns.

“It’s a really bright red eyeball in the Pacific,” says Andrew Leising, a research oceanographer at the US National Oceanic and Atmospheric Administration (Noaa). “It’s huge, it stretches across the whole [ocean].” The Pacific heatwave, which formed in May 2025, is already bringing surface temperatures 3-4C (5.4-7.2F) above average for this time of year, according to Leising.

Add to that: a massive warming pattern known as El Niño is brewing further south. El Niño is a weather phenomenon that pushes up global temperatures, and it is also supercharging Pacific Ocean warming. It is expected to intensify this autumn to become the strongest El Niño in living memory.

This combination of a massive marine heatwave and a “super El Niño” is rarely seen. Here are five impacts we can expect to see – and where they will happen.

El Niño is disrupting the Pacific’s marine food web from the bottom up

August 27, 2026 — As the 2026 El Niño strengthens in the equatorial Pacific, satellites are capturing the first major signs of disruption to the marine food web.

According to by NASA’s Earth Observatory observations, satellite measurements show a substantial drop in surface concentrations of chlorophyll across the Central Pacific compared with neutral conditions in June 2025. Chlorophyll is the pigment that helps plants absorbs sunlight to generate energy, and its reduction indicates a decline in phytoplankton, the base of the ocean’s food webs.

Hyung-Gyu Lim, an associate professor of oceanography at Chonnam National University in South Korea, told Mongabay by email that a developing El Niño can slow the process of upwelling, where nutrient-rich cold waters rise from the ocean depths to the surface. “This may trigger less nutrient supply. It is not surprising for me,” Lim said.

Earth is simmering in its hottest water temps on record, and that’s bad for fish and us

August 25, 2026 — The world’s oceans simmered to their hottest temperatures on record over the weekend and are likely to warm even further in the next few months, putting stress on life in the water and on land too, the European climate service Copernicus announced Monday.

Spurred by a still growing but already supersized natural El Nino and human-caused climate change, the world’s ocean temperatures hit 21.1 degrees Celsius (70 degrees Fahrenheit) on Friday and Saturday, narrowly edging out the average daily record set in March 2024, said Samantha Burgess, strategic climate lead for Copernicus.

“This is yet another sign of our climate system under strain and the ocean under immense pressure,” Burgess said.

Jane Lubchenco, an oceanographer and former chief of the U.S. National Oceanic and Atmospheric Administration called the record “very troubling.”

“An ocean this warm destabilizes weather patterns and threatens food security, economic prosperity and marine life,” Lubchenco said in an email. “A warmer ocean is not our friend.”

IFFO reports weak fishmeal and fish oil output as El Niño impacts fisheries

August 20, 2026 — IFFO – the Marine Ingredients Organization is reporting continued weak output of fishmeal and fish oil as a coastal El Niño weather pattern impacts raw material availability.

Scientists warned in July that a “Super” El Niño was likely to develop in 2026, causing a wave of different impacts on multiple global fisheries. Fisheries were already anticipating the phenomenon before it started to gain strength but, ultimately, could do little but react to warming water.

El Niño could bring highest sea levels ever recorded to CA coast

August 11, 2026 — A strengthening El Niño could bring the highest sea levels ever recorded to the California coast this year, raising the risk of widespread and damaging flooding.

It’s the latest effect forecast for what’s expected to be an historically strong event, one forecasters warn could also lash Southern California with powerful rain and broil both land and sea with punishing heat waves.

“We’re expecting likely the highest sea levels ever recorded on the California coast associated with this event,” said Mark Merrifield, director of the UC San Diego Scripps Institution of Oceanography’s Center for Climate Change Impacts and Adaptation.

During a recent online town hall, Merrifield presented a NASA satellite image showing sea levels already more than half a foot higher in the eastern Pacific Ocean compared to the reference state, and said by this fall and winter, “we should be seeing sea levels far above the average seasonal cycle.”

According to NASA, El Niño’s warmer ocean water displaces colder water close to the sea surface. Warmer water causes a rise in the sea surface height because water expands as temperature rises.

Data collected by scientists over the years also have shown how El Niños contribute to “enormously strong” waves, which can cause beaches to “erode and to narrow,” Merrifield said. “It’s well documented that during El Niño events, beaches across the entire state tend to move landward by about 30 meters [98 feet] or so.”

El Niño Alters Marine Life in the Pacific

August 11, 2026 — As of June 2026, El Niño has officially arrived. This naturally recurring phenomenon is characterized by warmer-than-normal water temperatures in parts of the equatorial Pacific along with changes to atmospheric and oceanic circulation patterns. Its regional effects range from desert floods to delayed monsoons to shifts in where tropical cyclones are more likely to form.

NOAA’s Climate Prediction Center expects the current El Niño to continue to strengthen through the end of 2026, with a 97 percent chance of lasting through early Northern Hemisphere spring 2027. Even during El Niño’s early stages, satellites have observed characteristic changes along the equatorial Pacific, such as warmer-than-normal sea surface temperatures and higher-than-normal sea surface height.

Among the first ecological downstream effects are changes to the marine food web. The maps above show chlorophyll-a concentrations—the pigment present in most phytoplankton—as observed by the OCI (Ocean Color Instrument) on NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) satellite. In June 2025 (left), conditions were neutral, while in June 2026 (right), El Niño was strengthening.

Birds Are Dying. Clues Point to El Niño.

August 7, 2026 — Every month, Giovanny Suárez Espín walks a beach near his home in southern Ecuador, monitoring for dead seabirds. Usually, he sees maybe a handful.

But on recent surveys, the sand has been littered with carcasses.

“Every 10 steps you took, you found five or 10 birds, and it kept going,” said Suárez, who works for American Bird Conservancy, a nonprofit group. “On the three-kilometer walk, we saw lots of dead birds the whole way.”

In June, Suárez and others tallied 638 dead birds on the beaches of three provinces in Ecuador, about seven times the number found over the previous year and a half combined.

“It’s painful,” he said.

In July, they counted an additional 968.

It’s too soon to say for certain what has caused the spike in deaths, which has affected various species, including sooty shearwaters, Peruvian and blue-footed boobies, cormorants, petrels and the critically endangered waved albatross. Die-offs in sea birds aren’t uncommon, and can stem from a variety of factors. In 2023, Ecuador saw mass deaths from avian influenza, said Sebastián Cruz, a seabird ecologist who runs the South American marine bird program for American Bird Conservancy.

But this time, he said, looks different. The birds’ bodies are emaciated. Testing for bird flu is needed, but the few necropsies that have been conducted, along with the behavior of surviving birds, show no signs of infection. And critically, sea surface temperatures off the coast have been exceptionally elevated.

This points to an alarming possibility: The seabirds could already be victims of the building El Niño, a natural climate phenomenon whose effects are now occurring while the planet dangerously warms.

In recent months, as scientists have predicted an El Niño that could be the strongest in recorded history, the attention has focused on how it could hurt humans. And it could hurt us a lot, potentially bringing record heat, drought and torrential rain.

But wildlife stands to suffer, too. Marine mammals and seabirds are among the most at risk.

Climate-driven disruption, constrained supply adding volatility to aquaculture markets in the back half of 2026

August 7, 2026 — Global aquaculture firms and the wider value chain entered the second half of 2026 facing a difficult combination of constrained supply, rising feed costs, climate uncertainty, and uneven consumer demand, according to Rabobank’s latest Global Aquaculture Update.

After weathering several major disruptions over the past decade, the industry has now entered a phase in which climate change, tightening feed ingredient supplies, and geopolitical uncertainty are reshaping global seafood markets, Rabobank Seafood Analyst Novel Sharma told SeafoodSource, explaining the industry should plan for continual uncertainty rather than treat each challenge as an isolated disruption.

El Niño’s ‘whole different ocean’ to send odd sea creatures to US

July 31, 2026 — An intensifying El Niño is forecast to make it “a sharky summer” off the California coast, with greater numbers of white sharks arriving with warmer waters from the south, but they are far from the only marine life expected to make surprise visits.

Strong El Niños can move several species of sharks, as well as rays, tropical fish, birds and even sea snakes northward into waters where they rarely appear.

“We expect to see all kinds of weird tropical things come up with this warm water,” said Douglas McCauley, director of the Benioff Ocean Initiative at the University of California, Santa Barbara.

The strongest El Niños – and this one is forecast to be among the very strongest – can alter entire marine ecosystems, shifting both animals and the food they need to survive.

Its ripple effects in winds, rain and ocean currents can extend across the world’s oceans. Studies have linked El Niño and its cooler water counterpart – La Niña – to starving sea lions in Peru, changes in sea turtle behaviors in the Caribbean and fisheries successes in the Amazon and Congo rivers.

El Niño can trigger “a lot of animal movement,” said Nate Jaros, a vice president of animal care at the Aquarium of the Pacific.

This summer, juvenile sharks and other aquatic visitors are turning up early, thanks to the effects of an intense marine heat wave already in place before El Niño arrives, McCauley said.

“We’re already seeing Mahi mahi. You’ll see more bluefin tuna, and you see weird stuff, like we’ll see more sea turtles and sea snakes,” McCauley said.
