The best time to sail Raja Ampat is the dry season, October to April — optimal weather, stunning underwater visibility, and favourable sailing conditions. Here is the month-by-month detail.
The Peak Season
The Best Month
November
Many seasoned travellers and charter companies agree November is the best month — peak underwater visibility (to 30 metres), warm water, dry weather, and gentle 5–10 knot winds for effortless cruising. Charter rates typically run $1,500–$4,000 per week, usually including meals, dive equipment, and experienced guides.

April
Tail of peak season — pleasant ~28°C, short afternoon showers, and full-moon coral spawning. Charter from ~$1,000–$2,800/week.

Off-peak tranquillity — fewer visitors, brief showers, and great birdwatching (Red Bird of Paradise on Waigeo). Charter from ~$800–$2,500/week.
The monsoon season, roughly May to September, brings strong winds and heavy rainfall — sailing conditions can become unsafe and diving visibility can drop. The most challenging months are June (rough seas and postponements), July (increased wave activity between islands), and August (less predictable, with many liveaboards not operating).
Especially for peak months (December–February), securing your yacht early saves money and ensures availability.
Light, breathable clothing, reef-safe sunscreen, and a good underwater camera for the vibrant marine life.
Weather can be unpredictable — a flexible itinerary leads to spontaneous adventures and undiscovered spots.
On remote islands, being respectful of local cultures and traditions enriches the whole experience.
