Research notes and updates from the team.
The SST forecast shows development of weak El Niño conditions by Jun-Aug, growing slightly to reach weak/moderate strength by the fourth forecast season of Sep-Nov. A positive Indian Ocean Dipole exists throughout the four forecast seasons, becoming slightly stronger by the fourth season. The tropical Atlantic maintains near to slightly above average SST during all four seasons.

OISSTv2 is often used for real-time analysis and model initialization, while ERSSTv4 is used for retrospective official ENSO diagnosis because it is more homogeneous over time, allowing for more accurate comparisons among ENSO events that are years apart.
