December in Labuan Bajo is the start of the rains, and nowhere near the washout people imagine. Expect hot, humid days broken by short, heavy downpours, seas that need a little more respect, and hills turning from gold to green. Boats still go out. Dragons still stand around looking prehistoric. And until the Christmas crowd lands, you’ll have a lot of it to yourself.
The honest version: December is a trade. You give up some certainty about the weather, and you get back space, softer prices early in the month, full waterfalls and the greenest version of Padar you’ll ever see. If your only window is Christmas to New Year, it’s a different story, and we cover that below.

Who this is for
Anyone deciding whether December works for a Labuan Bajo trip, or already locked into December and wondering what they’re in for. If you’re still comparing months, our guide to the best time to visit Labuan Bajo covers the whole year, and our wet season guide goes deep on November to March. This page is just December, in detail.
December weather in Labuan Bajo
| What | The December reality |
|---|---|
| Air temperature | 27 to 31°C, humid |
| Rain | Builds through the month. Short, heavy bursts, mostly afternoon or overnight |
| Sea state | More variable, with west-monsoon swell on some days |
| Crowds | Quiet until mid-December, busy Christmas to New Year |
| Landscape | Green and getting greener |
| Boat trips | Run most days, with occasional weather reshuffles |
December sits at the front end of the west monsoon. Early December often feels like a slightly stickier version of shoulder season. By late December the rhythm of build-up, downpour, clear-out is well established. Between showers the light goes washed and golden, and photographers cross oceans for less.
What the rain is actually like
Tropical rain here is an event with a beginning and an end, not a grey lid over the day. Most wet days deliver one or two hard bursts, often late afternoon or overnight, and then it’s done. All-day rain happens, but it’s the exception, and it’s rarer in December than in January or February.
The practical response is simple. Put your boat days early in your stay so you have room to reshuffle, keep a town day or a pool day in your back pocket, and don’t judge the whole day by an ugly sky at 6am. Weather moves through fast here.
Komodo boat trips in December
Trips run all December. The sea is the variable, not the park. The west monsoon can push swell through the outer sites, so operators sometimes reroute, swap islands or shuffle your day by 24 hours. A slow boat handles chop more comfortably than a speedboat, and our speedboat vs slow boat comparison walks through that trade-off. For a month-by-month picture of the water itself, see our Komodo sea conditions guide.
Quota pressure is low in early December, so booking a few days out is usually enough. From about 20 December, treat it like peak season and book weeks ahead. The system itself doesn’t change: every entry still goes through SiOra via your operator, which we explain in our guide to how to book Komodo National Park.
Diving and mantas in December
December opens manta season. From roughly December through February, plankton-rich water pulls mantas into the park’s cleaning stations in numbers, and sightings get very good. The trade is visibility, which varies more than in the dry months, and a few exposed sites that sit out the swell on rough days. Dive operators here plan around all of this daily. Our month-by-month Komodo diving guide covers which sites shine when.
The Christmas and New Year exception
From about 20 December to early January, Labuan Bajo fills up. Indonesian school holidays and international festive travel land at the same time, so rooms book out, boats fill, prices climb and the park’s daily quota becomes a real constraint again. If this is your window, book in this order: room first, boat straight after, both a few weeks ahead. New Year’s Eve in town is loud, cheerful and centred on the waterfront. It is not a secret escape, and it doesn’t pretend to be.
Why December is worth it
Padar’s famous viewpoint spends the dry season in browns and golds. In December it turns green, and the Padar and Pink Beach day looks like a different country. Cunca Wulang and the other waterfalls run full instead of trickling. Sunsets get theatrical with all that cloud to light up. And the town itself slows down: harbour-front tables without a wait, dive boats with spare seats, staff with time to talk. If you like places best when they’re not performing, early December is quietly one of the good windows.
What to pack for December
Everything on our Komodo day trip packing list, plus a light rain jacket, a proper dry bag for crossings, quick-dry everything and one warm layer for windy boat rides. Skip the umbrella. Sideways rain wins that fight every time.
Tips and mistakes to avoid
- Put boat days early in your stay and keep one spare day. Reshuffles are common, ruined plans are optional.
- Travelling between Christmas and New Year? Book the room, then the boat, weeks ahead. Early December needs no such nerves.
- Prone to seasickness? Choose the slow boat and sit low and central. December seas reward the unhurried.
- Don’t cancel a trip because of a grim morning sky. Ask your operator instead. They read this weather for a living.
- Waterproof your phone and camera on crossings, even on calm days. Spray is part of the deal.
