The El Niño Southern Oscillation is currently neutral. There are some early signs that a La Niña might form in the Pacific Ocean later in 2024. As a result, the Bureau's ENSO Outlook has shifted to La Niña Watch. When La Niña tch criteria have been met in the past, a La Niña event has subse-quently developed around 50% of the time. There is about an equal chance of neutral ENSO conditions in the same outlook period. Sea surface temperatures (SSTs) in the central Pacific have been steadily cooling since December 2023.
