Latest status of El Niño and La Niña

El Niño and La Niña
Latest status (October 2024)


In the past month or so, sea surface temperatures of the central and eastern equatorial Pacific were near normal on the whole. Based on the latest oceanic observations as well as forecasts by a number of climate models around the world, the cooling of the central and eastern equatorial Pacific is expected to continue for the rest of this year. The sea surface temperatures of the region are likely to be normal to below normal for the rest of this autumn and winter 2024/25, with a possibility of transitioning to La Niña conditions in the coming winter.
