July 2025 Quick Look

As of mid-July 2025, the equatorial Pacific remains in an ENSO-neutral state, with sea surface temperatures in the Niño 3.4 region close to average. The IRI ENSO plume forecast indicates a high probability (75%) of ENSO-neutral conditions for Jul–Sep 2025. These neutral conditions are expected to persist through the end of the forecast period. For later seasons (Oct–Dec and Nov–Jan), the probabilities for ENSO-neutral decrease slightly to 49% and 49%, respectively, but remain higher than those for either La Niña or El Niño. Looking ahead to the 2025/2026 period, ENSO-neutral once again becomes the dominant category, with gradually increasing probabilities.
