La Nina 2025 Australia Map. What is the La Niña and what does it mean for Australian weather? ABC A La Niña Advisory is currently in place with a 59% chance of continuing through April 2025 Average sea surface temperatures in the Niño-3.4 region of the equatorial Pacific Ocean were at least 0.5°C (0.9°F) warmer than average (5°N-5°S, 120°W-170°W) in the preceding month, and the anomaly has persisted or is expected to persist for 5 consecutive, overlapping 3-month periods (e.g., DJF, JFM, FMA, etc), and the atmosphere over the tropical Pacific exhibits.

2-year history of sea surface temperatures in the Niño-3.4 region of the tropical Pacific for all La Nina events since 1950 (gray lines) and the recent (2024-25) event (purple line). Sustained positive values are indicative of La Niña conditions, and sustained negative values indicative of El Niño conditions

El Niño and La Niña generally have an autumn to autumn pattern of evolution and decay. How does it affect Australia? Each phase of the ENSO has a very different effect on the Australian climate The Nino3.4 index passed the La Niña threshold in December 2024 and La Niña conditions are supported by cool subsurface temperature anomalies in the central Pacific
High chance La Niña will continue through January WFLA. Sustained positive values are indicative of La Niña conditions, and sustained negative values indicative of El Niño conditions This shift allows the very warm pool of water near Australia to move east toward South America.
