Apr – Jun
The quiet window
Seas calming after the wet season, landscapes still green, crowds below peak, nights around 21–22 °C in June.
Silo 2 · Planning
April to June, or September to November
The shoulders of the dry season are the answer for almost every wellness trip here: calm enough seas, clear water, and the breathing room that July and August do not have.
- Independent, not an operator
- Trade-offs named, not hidden
- Free, no obligation
- 800–1,000 mm Annual rainfall — unusually dry
- ~36% Humidity inside the park
- 25–40 m Peak visibility in the north
- 10–30+ Mantas per dive, Dec–Feb
The short answer
The short answer
April to June is the best overall window; September to November is the close second. Both give calm seas, comfortable temperatures and sub-peak crowds — and for a wellness trip, sea state matters more than the last few metres of visibility.
- Komodo is one of the driest regions in Indonesia, which is why the "wet season" here is far less absolute than elsewhere in the country.
- What actually varies is the sea. Comfort on a boat is the variable that decides whether a sailing retreat works.
- July and August have the best water and the most people. The daily park cap is felt hardest then.
- And the genuine trade-off: manta encounters peak in exactly the months the seas are roughest.
When to go
The four windows
What each part of the year actually delivers, and who it suits.
See all retreat formats
Apr – Jun
Jul – Aug
Driest, busiest, priciest
The best underwater visibility of the year, and the highest prices, the most boat traffic and the strongest south-east winds.
Sep – Nov
The second prime window
Excellent conditions with far fewer boats than peak, and the southern manta aggregations building toward December.
Dec – Mar
Rough seas, peak mantas
The roughest water and the highest seasickness risk on smaller vessels — and exactly when manta encounters peak.
The trade-off
Calm seas or peak mantas?
These two things do not coincide, and pretending otherwise is how people end up seasick on a trip they booked to relax on.
-
Sea state
- Shoulder (Apr–Jun, Sep–Nov)
- Calm to moderate. Comfortable for deck practice and for sleeping aboard.
- Wet season (Dec–Mar)
- Rough, particularly January and February. Some sites inaccessible.
-
Mantas
- Shoulder (Apr–Jun, Sep–Nov)
- Building through October and November at the southern sites.
- Wet season (Dec–Mar)
- Peak. Reports of 10–30+ per dive at Manta Point and Manta Alley.
-
Crowds
- Shoulder (Apr–Jun, Sep–Nov)
- Below peak. Anchorages often quiet.
- Wet season (Dec–Mar)
- Lowest of the year — some operators reduce schedules entirely.
-
Landscape
- Shoulder (Apr–Jun, Sep–Nov)
- Still green in April to June; drying through September.
- Wet season (Dec–Mar)
- Greenest, and the inland scenery is at its best.
-
Who it suits
- Shoulder (Apr–Jun, Sep–Nov)
- Almost every wellness traveller, and anyone prone to seasickness.
- Wet season (Dec–Mar)
- Divers who came specifically for mantas and do not mind the crossing.
If you are prone to motion sickness, treat December to February as a diving decision rather than a wellness one — and start the medication before you board, not when you feel it.
Planning by format
What the season means for your trip
Season affects each format differently. Find yours.
If you are sailing
Sea state is everything.
- April–June and September–November are the comfortable windows
- Book 2–4 months ahead for July–August
- Dec–Feb: expect movement, and plan medication in advance
- Ask the operator which southern sites are reachable on your dates
If you are land-based
Season matters far less.
- Spa access is year-round and unaffected by sea state
- Wet season is greener and cooler inland
- Park day trips are the part the weather actually cancels
- Shoulder months give the best rate-to-conditions ratio
If you are diving
The calculation is different.
- July–August: best visibility, 25–40 m in the north
- September–November: excellent conditions, far fewer boats
- December–February: manta season, roughest crossings
- Water sits around 27–28.5 °C through the shoulder months
Before you book
Frequently asked questions
What is the best month for a wellness retreat?
May or June if you want one month. Seas are calming after the wet season, the landscape is still green, temperatures are comfortable with night lows around 21–22 °C in June, and visitor numbers have not peaked. October is the equivalent on the other side of the year. Both give you the conditions without the July–August crowding.
When are the seas calmest?
April to June and September to November. These are the windows where a multi-day sailing is comfortable rather than endured. January and February bring the roughest water of the year, with storms possible and some sites inaccessible — which matters much more on a small vessel than on a large one.
Can I do yoga and diving in the wet season?
You can dive — and manta encounters peak then. Yoga on a moving deck is another matter: a phinisi in February moves enough that balance work is unrealistic, so sessions get confined to anchorage hours or cancelled. If the practice is central to your trip, do not book December to February.
When is manta season, and does it change planning?
Encounters build from October and peak December to February at the southern sites, with reports of 10–30+ per dive. It changes planning in one specific way: the best manta months are the worst sea months. If mantas are the reason for the trip, accept the crossings. If recovery is the reason, come in the shoulder and take what the mantas give you.
How far ahead should I book?
Two to four months for July and August, when the park cap and the better vessels both fill. Four to eight weeks in the shoulder months is usually enough. Park permits are tied to your passport and travel date through the SiOra system, so the dates need to be fixed before the permit exists.
