Latest News About El Niño–Southern Oscillation

Here’s the latest on El Niño–Southern Oscillation (ENSO) based on recent authoritative briefings:

• The current signal is shifting toward ENSO-neutral, with conditions likely remaining neutral through the Northern Hemisphere spring and into early summer 2026. This is the result of NOAA CPC/NCEP/NWS updates and related climate summaries, which note the end of La Niña and a transition to neutral, with a growing possibility of El Niño developing later in 2026 if warming in the central/eastern Pacific intensifies. [NOAA CPC/NCEP/NWS guidance and Climate.gov ENSO updates]

• Outlooks suggest a higher chance of El Niño forming from mid-2026 (May–July window) and persisting into late 2026, contingent on oceanic warming and atmospheric coupling in the tropical Pacific. Probabilities in the most recent outlooks place emphasis on a transition from neutral to El Niño later in the year if SSTs in the Niño-3.4 region rise above thresholds.

• ENSO’s global impacts vary by phase and region, but neutral conditions generally imply a mixed set of typical patterns with fewer extreme ENSO-driven anomalies than strong El Niño or strong La Niña events. Regions commonly affected include parts of North America, South America, Africa, and Asia, with rainfall and temperature impacts linked to the evolving state of the Pacific.

Illustration: A typical ENSO progression recently has moved from La Niña to ENSO-neutral, potentially toward El Niño in 2026, with the timing and strength dependent on ongoing ocean-atmosphere coupling.
