Weak La Niña conditions are rapidly fading as tropical Pacific indicators signal transition toward ENSO-neutral state
Sea surface temperatures and atmospheric patterns show clear departure from La Niña baseline, creating uncertainty for global weather systems through mid-2026
| Period | Scenario | Probability | Confidence |
|---|---|---|---|
| Mar-May 2026 | ENSO-Neutral | 60% | Moderate |
| Mar-May 2026 | La Niña | 30% | Low |
| Mar-May 2026 | El Niño | 10% | Very Low |
“El Niño and La Niña are not the only factors that drive global and regional climate patterns, and the magnitudes of ENSO indicators do not directly correspond to the magnitudes of their impacts.”
ENSO transitions create crop planning chaos for farmers, destabilize global agricultural systems, and drive food prices beyond reach for vulnerable populations worldwide
Coastal storm patterns shift
Agricultural zones face uncertainty
Food security vulnerabilities
Substantial uncertainty exists in current projections due to widespread disagreement among tropical Pacific sea surface temperature forecasts across models and ensemble members
