El Nino looms large over U.S. Winter Outlook

10/17/2026 - By noaa.gov, noaa.gov. NOAA’s U.S. Winter Outlook, released today, shows how El Nino will likely influence the upcoming winter months (December 2026 to February 2027), with warmer-than-average temperatures expected across the northern U.S.; wetter-than-average conditions likely across the southern U.S., from California to Florida, and along the Eastern Seaboard; and drought improving… SEE MORE

How Will El Niño Affect Your Local Fisheries?

10/10/2026 - By fisheries.noaa.gov, fisheries.noaa.gov. What does El Niño mean for U.S. fisheries and marine life? What can fishermen and coastal communities expect to observe and experience as this event continues and potentially intensifies? And what are scientists at NOAA Fisheries doing to track this natural phenomenon? The El Niño-Southern Oscillation is a powerful… SEE MORE
Coastally-trapped Kelvin waves, a signature of El Niño, traveled north along the West Coast during the 1997/1998 El Niño, as shown in a map of sea surface height anomalies. Darker reds show sea levels higher than normal, while darker blues show heights below normal. Scientists are now watching for similar waves to move up the West Coast this fall.

Ocean Indicators Help Track El Niño’s Arrival on the West Coast

9/5/2026 - By fisheries.noaa.gov, fisheries.noaa.gov. 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… SEE MORE

7 Ways El Niño and Large Marine Heatwave Could Affect West Coast Marine Species

6/23/2026 - By fisheries.noaa.gov, fisheries.noaa.gov. A large marine heatwave has bathed parts of the West Coast in very warm ocean waters over the past year, breaking temperature records in the Pacific. NOAA has also announced that El Niño has developed in the tropical Pacific and is predicted to intensify to a moderate or strong level this… SEE MORE

El Niño and High Tide Flooding, a Possible Double Whammy for Some Coastal Communities in 2026

5/24/2026 - By oceanservice.noaa.gov, oceanservice.noaa.gov. NOAA’s National Weather Service is predicting El Niño is likely to emerge by July 2026 and continue through the winter, and for many locations in the U.S. this could mean more high tide flooding. To understand why more flooding is expected, it helps to understand what El Niño is and… SEE MORE
