EL NIÑO SOUTHERN OSCILLATION – ENSO
April 17th 2024
Current State: TRANSITION TO NEUTRAL CONDITIONS


  • During the last 30 days, sea surface temperatures at equatorial Pacific Ocean were above normal from 110°W and 160°E. Cold anomalies were observed at 100°W, near the South American coast.

  • During the last 30 days, trade winds at equatorial Pacific Ocean region were weaker than normal at east of the dateline and were stronger than normal at west of the dateline.

  • Sub-surface ocean water temperatures at equatorial Pacific Ocean were warmer than normal between the dateline and the South American coast, from surface to 50 m depth. Cold anomalies were present from 50 to 250 m depth.

  • 30-day moving SOI (Southern Oscillation Index) was around neutral values since early March. Its latest value is -3.3 (ending on April 14).

  • During the last 30 days, convection at equatorial Pacific Ocean was below normal around the dateline.

  • Dynamical and statistical models predict for El Niño region, 85 % chances of transition to neutral conditions during the season April-May-June 2024.
