Kiribati Ocean Outlook
Issued 14 September 2026
Summary
- The sea surface temperature is forecasted to remain warmer across the Kiribati region.
- An increase in sea surface height remains at the Northern Line and Phoenix group and this is correlated with a warmer sea surface temperature over those areas. The remaining islands are expecting near-normal.
- The upwelling zone is expected to cover most of the Kiribati water. High tuna-catches is likely over these areas.
- The coral bleaching outlook indicates Alert Level 2 at the Central Gilbert and most parts of the Line and Phoenix group while Alert level 1 for the Southern Gilbert - there is an expectation for coral mortality. The rest of the islands indicate no stress.
- The next extreme spring tides is forecasted to occur on the 28th September at 5:19PM with an height of 2.82 metres. The public are advised to take precautions to minimize possible threats from extreme spring tides.
September – November 2026
Ocean conditions and outlook
Sea surface temperature
Warmer sea surface temperature persists across the Kiribati region.
Sea surface height
Due with warmer sea surface temperature across the Kiribati region, the sea surface height is expected to increase at the Northern Line and Phoenix while the rest of the islands are near-normal.
Fisheries convergence zone
The convergence zone (purple line) shown on a regional scale is forecasted to lie over the Kiribati water. These areas are expected to be more favorable and rich in migratory species like tuna.
Coral bleaching
To correlate with warmer sea surface temperature for the next three months, the coral bleaching is forecasted to be on Alert level 2 over the Central Gilbert and most parts of the Line and Phoenix group. The Northern Gilbert is on Alert Level 1 while islands at futher north (Makin and Butaritari) indicates no stress.
Tide outlook and moon phases
tide levels for September to November 2026. The highest tides within these three month is projected to reach 2.89 m, occurring on 25th of November at 4:47pm.
Actions for the Fisheries sectors against the available parameters.
