Research notes and updates from the team.
In October 2023, sea surface temperatures (SSTs) in the central-eastern equatorial Pacific Ocean were well above the El Niño threshold (the NINO3.4 index value in October 2023 was +1.59 °C), while the weekly-averaged SST anomalies in the NINO3.4 region was +1.80 °C during the week centered on 08 Nov 2023.

The most recent weekly (11 Oct 2023) anomaly in the NINO3.4 region was +1.50 °C, suggesting that the tropical Pacific is experiencing moderate strength El Niño conditions.
