The ECMWF seasonal expects El Niño to peak in the central Pacific around the new year — and linger into June.

In the eastern Pacific, near Ecuador, Peru and Chile, twin El Niño peaks are predicted in November and May, with immense ocean heat lasting for at least six more months.

📈 Since the start of the year, scientists with Scripps Oceanography's Shore Stations Program and Coastal Ocean Observing Lab have recorded 73 days (and counting) of record-high water temperatures off Scripps Pier. 🧵 ⤵️

Sea surface temperature anomalies in the central and eastern equatorial Pacific, the region at the heart of El Niño, could reach 3.7°C in October–December, which is forecast to be the highest on record.

This is one of the most striking graphics I've ever seen.

Off San Diego, 54°F (12°C) water now sits 300 feet deeper than it did in August.

You can literally see the Kelvin wave associated with El Niño pushing north along the California coast, bringing warm water up from the south, deepening the thermocline and rapidly warming sub-surface waters.

It's one of the most extreme marine heatwaves in California's history.

El Niño continues to strengthen, with a strong-to-very strong El Niño likely through January-March 2027 (remaining greater than a 79% chance). An #ElNino Advisory remains in effect. #ENSO https://t.co/5zlzaZ1aZx

New data from #ClimateCentral reveals the growing toll of costly U.S. wildfires.

The U.S. has experienced 453 billion-dollar wildfires since 1980, costing $3.2 trillion and claiming an estimated 17,200 lives.

The El Niño-driven period of wet and stormy weather across Florida will soon begin.

Beginning next week, the subtropical jet and moist air will combine to produce a consistent period of stormy weather that will plague FL for much of winter.

We could be seeing storms trek across Florida weekly beginning next week, bringing with it an above-average flood and severe weather threat through at least January. I have particular interest in a potential storm system next Tuesday. More on that to come.

El Niño's warm water is still moving east across the Pacific, and more strengthening is expected.

Subsurface ocean waters just reached their most anomalous point in this event so far: 12.2°C above average in the Niño 3 region — with water temperatures around 30.8°C (87.4°F).

[Copernicus ECMWF @CopernicusECMWF]

Latest Climate Bulletin: 2026 is virtually certain to surpass 1.5°C above pre-industrial levels, record high global air & global sea surface temperature for October, river flows remain exceptionally low, 2nd lowest Antarctic sea ice extent for October.

Water temperatures along California coast continue to warm & have now reached genuinely *astonishing* levels. At the Farallon Islands--usually the epicenter of NorCal's infamously frigid upwelling zone--temps now exceed 66F, shattering all records for this late in calendar year.

[Colin McCarthy @US_Stormwatch]

California is experiencing one of the most extraordinary marine heatwaves in it's history. Water temperatures off Santa Barbara reached nearly 75°F today, 12°F above normal. Off San Diego County, temperatures reached above 77°F in the past week.

From the Bay Area to San Diego, coastal waters are running 6–12°F above normal. Category 5, or “beyond extreme,” marine heatwave conditions are occurring along virtually the entire Southern California coast.

Farther north, temperatures off Monterey have reached 68°F and 67°F off Half Moon Bay.

This exceptional warmth could have major consequences for marine life and could help enhance storms this winter.
