Here’s a concise update on the latest ENSO news.
-
What ENSO is: The El Niño–Southern Oscillation (ENSO) is a periodic climate pattern defined by sea surface temperature (SST) variations in the central/eastern tropical Pacific and corresponding atmospheric changes.[3][8]
-
Current state as of early 2025–2026: After a La Niña phase, most official sources indicate a transition to ENSO-neutral conditions, with forecasts suggesting neutral conditions through at least the Northern Hemisphere summer 2025, before potential development of El Niño later in 2025 or 2026 depending on evolving ocean-atmosphere indicators.[2][5][3]
-
Forecaster outlook: The Climate Prediction Center and other agencies have been signaling that ENSO-neutral conditions were expected to persist through spring and into summer, with increasing odds of El Niño formation later in 2025 or 2026 based on SST anomalies in Niño regions and atmospheric feedbacks.[5][3]
-
Why it matters: ENSO conditions influence global weather patterns, including rainfall, drought risk, and hurricane activity, with stronger Niño phases typically increasing winter rainfall in some regions and altering storm tracks, while La Niña and neutral phases have different regional impacts.[3][5]

The WMO El Niño/La Niña Update is based on several oceanic and atmospheric indicators, including: SST anomalies in the equatorial Pacific Ocean, especially in the Niño 3.4 region Atmospheric pressure variations, measured by the SOI, which reflects the difference in air pressure between Tahiti and Darwin, Australia Subsurface ocean temperature anomalies which indicate the presence of warm or cold water below the surface Trade winds and atmospheric circulation which influence ocean-atmosphere...
