  • Between mid-August and September trade winds at equatorial Pacific Ocean region were stronger than normal between 140°E and the South American coast.

  • Sub-surface ocean water temperatures at equatorial Pacific Ocean were colder than normal between 140°W and 150°E, from 100 to 200 m depth. Warmer temperatures were present at west of 160°W and at east of 130°W, at less depth.

  • 30-day moving SOI (Southern Oscillation Index) had negative values during August and positive values during September. Its latest value is +5.8 (ending on September 17).

  • During the last 30 days, convection at equatorial Pacific Ocean was slightly below normal around the dateline and above normal at west of 170°E.
