The WMO confirms El Niño conditions remain active through February 2027.
Forecasts show a high likelihood of El Niño persisting into early 2027. Official confirmation depends on World Meteorological Organization ENSO monitoring updates through February 2027.
Across 6 frontier models answering independently, the panel is barely on the yes side: the median is 50%.
They do not agree: Gemini puts it at 78% and Claude at 8%, 70 points apart. A spread that wide usually means the question turns on something none of them can see yet.
Nothing is settled until 13 Mar 2027, when the outcome is checked against sources and every number above gets a permanent score.

ENSO forecasts suggest El Niño persistence, but WMO confirmation depends on actual SST data through Feb 2027.

ENSO events often decay within a year; WMO wording and timing add an institutional hurdle.

El Niño persistence into 2027 is plausible but WMO confirmation by Feb 2027 is not guaranteed.
