Best Time to Visit Raja Ampat Indonesia

10/10/2025

Raja Ampat needs no introduction; it is one of the most legendary cluster of islands and waters in Indonesia. This is especially true for scuba divers and snorkeling enthusiasts who want to get a glimpse of an underwater paradise like no other.

And while the magic of Raja Ampat never completely fades, when you go can completely change the experience. From manta-filled dives and glass-calm seas to lush green islands and quiet anchorages, each season in this remote corner of Indonesia brings something unique.

Here’s everything you need to know about the best time to visit Raja Ampat, whether you’re a diver chasing visibility, or a traveler looking to explore above the waterline.

Overview: Weather and Seasons in Raja Ampat

Raja Ampat sits right on the equator, which means it’s warm and humid year-round with daytime temperatures around 31 °C (88 °F) and nights averaging 25 °C (77 °F). You’ll get 12 hours of daylight every day, and water temperatures stay an inviting 27–30 °C (81–86 °F).

There are two broad seasons:

Dry Season (October–April) → Calmer seas, clearer skies, and peak diving conditions.
Wet Season (May–September) → Occasional rain and stronger winds, but vibrant landscapes and fewer crowds.

Even in the so-called “wet” season, Raja Ampat doesn’t shut down, you can dive, snorkel, and explore all year. Just expect short tropical showers rather than long days of rain.

Best Time for Diving Raja Ampat

If you’re here to dive, plan your trip between October and April, when:

The seas are calmest
Visibility reaches 20–30 meters
Water temperatures stay around 28–30°C
And manta rays gather at cleaning stations like Manta Sandy and Blue Magic

The peak diving season runs November to March, when the marine life density is at its highest, think schooling jacks, reef sharks, turtles, and the famous oceanic mantas.

Month	Conditions	Visibility	Highlights
Nov–Mar	Peak diving season	25–30m	Manta migrations, calm seas
Apr	Shoulder season	20–25m	Great mix of calm & quiet
May–Sep	Windier, wet in south	10–20m	Fewer boats, cheaper trips

During May–September, diving continues in the northern Dampier Strait, which remains sheltered. Southern Misool often becomes rougher due to southerly winds, but reefs stay thriving and empty.

✅ Pro tip: Divers after tranquility and discounts should aim for April or early October, calm seas, healthy reefs, fewer crowds.

Best Time for Non-Divers & Leisure Cruising

If your Raja Ampat adventure is more about exploring above water — kayaking lagoons, hiking viewpoints, birdwatching, or just sailing between emerald islands — then the dry season (October–April) is ideal.

November–March: Calm seas for smooth sailing, great for liveaboards and private charters.
April–May: Green landscapes, gentle light for photography, and low crowds.
September–October: Transition months with warm days and glassy bays.

🌿 The wet season (May–August) paints the islands lush green and keeps wildlife active, perfect for birdwatching (especially the rare Birds-of-Paradise on Waigeo). Just expect the occasional tropical downpour.

Combined Best Time for Diving & Island Adventures

For those wanting the best of both worlds, world-class diving and relaxed cruising, aim for November to March.
This is when:

The weather is mostly dry and predictable
Currents are mild enough for all skill levels
Visibility peaks, and manta sightings are common
You can dive in the morning, kayak in the afternoon, and hike for sunset

If you prefer fewer people and lower rates, April and October are the sweet spots.

Trip Type	Ideal Months	Notes
Dive-Focused	Nov–Mar	Calm seas, mantas, best visibility
Leisure/Private Charters	Oct–Apr	Dry weather, smooth sailing
Photography & Birdwatching	Apr–Jun	Green landscapes, fewer tourists
Mixed Diving & Exploring	Oct, Apr	Balanced weather, better prices

Season Tips

Dry Season (October–April)

Expect 5–10 brief rain days/month, usually tropical showers, not full days of rain.
Book early: 80% of liveaboard trips sell out in high season.
Water temps: 27–30°C; Visibility: 20–30m.
Great for both divers and non-divers, every island is accessible.

Wet Season (May–September)

Fewer crowds, 20–40% off on some charters.
