Research notes and updates from the team.
In January 2023, equatorial sea surface temperatures (SSTs) in the central-eastern Pacific Ocean remained cooler than normal, exhibiting persistent La Niña conditions (the NINO3.4 index value in January 2023 was -0.75C). The most recent weekly (08 Feb 2023) anomaly in the NINO3.4 region was -0.5 °C, showing a weakening of the current La Niña conditions in the tropical Pacific.
