Research notes and updates from the team.
During April 2024, there was a further decline in the sea surface temperatures (SSTs) within the central-eastern equatorial Pacific Ocean compared to the preceding month, leading to a NINO3.4 anomaly index value of +0.81 °C. The weekly-averaged SST anomalies in the NINO3.4 region were +0.30 °C for the week centered on May 08, 2024.

The most recent weekly (week centered on 10 April 2024) anomaly in the NINO3.4 region was +0.90 °C, indicating that the tropical Pacific is experiencing gradually weakening El Niño conditions.
