Latest status of El Niño and La Niña

El Niño and La Niña
Latest status (May 2024)

In the past month or so, El Niño continued to weaken. Based on the latest oceanic observations as well as forecasts by a number of climate models around the world, the El Niño is transitioning to the ENSO-neutral state. Subsequently, sea surface temperatures over the central and eastern equatorial Pacific are expected to continue to decrease, indicating that La Niña may start to develop in the latter half of 2024.
