During 2026, marine heatwave (MHW) NEP25A persisted at record intensity off the Southwest Coast of North America. NEP25A is a significant contributor to the record warm U.S. thermal pattern for all of 2026 so far especially the Southwest States. Contributions to the anomalous warmth were also made during recent months by expansion of the Kuroshio MHW and the subtropical North Atlantic MHW.

The week 3-5 HDD projections are mixed but trending colder. Notable is the colder AI solutions. 3 of 5 late November East Pacific oscillation (EPO) forecasts are negative supporting potential for a “polar vortex” pattern to close the month. Additionally, negative arctic oscillation (-AO) is expected suggesting high latitude blocking. The potential for a chilly end to November is increasing.

The October 2026 upper ocean heat anomalies across the equatorial Pacific Ocean indicate values peaked during September and eased slightly in October although still record warm.

Stratospheric warming develops during early November in parts of the polar region with varying response within the troposphere in the middle latitudes. The stratospheric warming event causes North Atlantic oscillation (NAO) to shift to moderate negative phase. The -NAO pattern will produce cold weather in Europe peaking next week.

A classic intense negative outgoing longwave radiation anomaly signature representing persistent convection near and east of the Dateline beginning late last May and representative of rapidly developing El Nino has weakened during the past week. For the first time since earlier this year, the southern oscillation index has shifted positive. Has Super El Nino 2026 reached peak intensity?

Regional SSTA in South Atlantic Influencing Brazil Rainfalll
The SSTA regime in the South Atlantic is relevant to the prevailing rainfall pattern across Brazil. Currently, an intense marine heatwave is located in the eastern subtropics with attendant warming extending across the South Atlantic index zone which is a robust +1.28C. Meanwhile, a cool pool of SSTA rests off the Southeast Brazil coast.

Super El Nino Peaking. Expecting Rapid Demise During Early 2027.
Has Super El Nino 2026-27 peaked? What follows Super El Nino? Of course, forecast model opinion varies. However, the recently developed observed and forecast choppy southern oscillation index suggests the oceanic and atmospheric Super El Nino is peaking now. The eastward push of cool subsurface water east of the Dateline suggests that while fuel to sustain Super El Nino for boreal winter 2026-27 remains buoyant, an ending to warm ENSO is on the horizon.
