Indian Ocean Coral Bleaching
Temperatures in decline across the WIO, positive outlook for recovery.
Temperatures are in decline across the region and no coral mortality has yet been reported. Widespread moderate bleaching in northern parts of the WIO should stabilize and dissipate in coming weeks, with only slight residual risk in Kenya/Somalia and NW Seychelles. The 4th global bleaching event was announced on 15 April, at the end of the bleaching period in the WIO.
