Latest status (December 2025)
In the past month or so, the sea surface temperatures of the central and eastern equatorial Pacific cooled and became colder than normal in November 2025. Based on the latest oceanic observations as well as forecasts by a number of climate models around the world, while the sea surface temperatures of the central and eastern equatorial Pacific will remain colder than normal for most of the time in the next couple of months, the sea surface temperatures of the region are expected to rise gradually and return to near normal in February to March 2026.
