Season planner for Raja Ampat
Warm, equatorial conditions dominate. October-April is typically calmer with more manta activity at cleaning stations. May-September often brings stronger southeast trades that can roughen crossings, though sheltered reefs still shine. Turtles nest on remote islets with hatchling releases peaking mid-year.
