Bali in December: Weather, Rain, Crowds and Where to Stay

Bali in December is the month when the rainy season and the busiest holiday weeks of the year arrive together. That clash is the whole problem: you can pay peak prices and still lose your afternoons to rain, or you can pay far less and get calm mornings on a clean beach. The difference is which half of the month you pick and which coast you sleep on. This guide gives you the numbers, the coast-by-coast verdict and two routes that work with the weather.

Bali in December at a Glance: 6 Numbers That Decide Your Trip

This section gives you the month in figures, so you can judge it before you read anything else. Bali sits just south of the equator, so the temperature barely moves through the year. What changes in December is the rain, the humidity and the sea.

What	December in south Bali	What it means for you
Day / night temperature	About 31 °C / 25 °C	Hot at all hours; air conditioning or a good fan matters
Rainfall	About 250 to 300 mm	One of the three wettest months of the year
Days with rain	About 16 to 20	Rain on most days, but rarely all day
Sunshine	About 7 hours a day	Mornings are often bright; cloud builds after lunch
Daylight	About 12.5 hours	Sunrise is early, so early starts are easy
Sea temperature	About 29 °C	Warm everywhere; conditions depend on the coast
Crowds	Low to mid until about the 20th, then peak	Two different months in one
Prices	Good value early, highest of the year late	Your dates matter more than your hotel class

The climate figures are long-term averages for Denpasar, on the south coast, as published by Climates to Travel’s Bali climate tables. Other long-term datasets put the rain days closer to 20, which is why we give a range. Individual years differ, and a wet year can start earlier or run later.

Humidity sits around 80 per cent or higher, so 31 °C feels hotter than the number suggests. The sun is also strong: the UV index reaches the extreme band on clear mornings, even when the afternoon turns grey. Sunscreen matters as much as a rain jacket.

How the Rain Really Works: The 4-Part December Day

This section explains the daily rhythm, because it is the single most useful thing to know. Most first-time visitors picture a rainy season as a grey week. In Bali it behaves more like a timetable.

Build your days around that pattern and you lose very little. Fight it, with a 3 pm beach club booking or a sunset temple visit every day, and the month will feel worse than it is.

Storms can be dramatic. Lightning is common, and the heaviest bursts can drop a large share of the day’s rain in under an hour. Tropical cyclones occasionally form over the ocean south of Indonesia between November and May. They rarely come near Bali itself, but a distant one can bring several days of wind, swell and steady rain.

Which Coast in December? The Area-by-Area Verdict

This section tells you where to sleep, which is the decision that changes your trip the most. Bali’s weather differs by coast and by height, and so does the sea. Most advice treats the island as one place. It isn’t.

Area	Sea and beach	Rain	Verdict
Sanur	Reef-protected, calm, good for swimming	Typical for the south	Go: the easiest December base
Nusa Dua	Sheltered, usually the cleanest water	Typical for the south	Go: best for families and resort stays
Uluwatu and the Bukit	Cliffs and views; sea often rough	Slightly drier than inland	Go for scenery, not for swimming
Seminyak, Legian, Kuta, Canggu	Rough surf; debris often washes ashore	Typical for the south	Go with care: food and nightlife yes, beach no
Ubud and the foothills	No beach	Wetter than the coast	Go: green, cooler evenings, best in the mornings
Bedugul, Munduk, Kintamani	No beach	Cloudiest and wettest	Go with care: short visits, early starts
Amed and the north-east	Calm bays, snorkelling from shore	Often drier than the south	Go: the quiet alternative
Nusa Lembongan and Nusa Penida	Boat crossings can be rough or cancelled	Similar to the Bukit	Go with care: leave a spare day

The west coast: why the famous beaches disappoint

Kuta, Legian, Seminyak and Canggu face the open ocean to the west. In the rainy season the wind turns onshore, the surf gets messy, and currents carry plastic and driftwood onto the sand. Clean-up crews work daily, but the beaches can look rough for days at a time.

That doesn’t make the area a mistake. The restaurants, cafes, shops and beach clubs run as normal, and the sunsets between storms can be the best of the year. Just don’t choose it for swimming.

The east and south-east: where the sea behaves

Sanur sits behind a reef on the east-facing side, so the same wind that spoils the west leaves its lagoon calm. Nusa Dua, a little further south, is sheltered too and is usually the clearest water on the island in the wet months.

Both are flat, walkable and well set up for families. Sanur is also the main harbour for boats to the Nusa islands, which saves a road transfer on a rainy day.

Ubud and the highlands: greener, wetter, cooler

Ubud sits in the foothills, where cloud builds earlier and rain falls more often than on the coast. The reward is colour: the rice terraces, ravines and gardens are at their greenest, and the evenings are a touch cooler.

Above about 1,000 metres, around Bedugul, Munduk and Kintamani, it is cloudier again and cool enough at night for a light layer. Waterfalls are at full force. Paths are slippery, and some become unsafe after heavy rain.

The north-east: Bali’s quiet rain shadow

Amed and Tulamben lie in the lee of Mount Agung and are often drier than the south. The black-sand bays are calm, and you can snorkel over coral straight from the beach. It’s a long drive from the airport, so stay at least two nights.

Crowds and Prices: The Two Halves of Bali in December

This section shows you which dates are cheap and which are the dearest of the year. December is really two months. The first is low season with rain. The second is the peak of the peak.

Dates	What happens	What it means for you
1 to about 15 December	Low season: quiet beaches, restaurants and roads	Best value of the month; book a week or two ahead
About 16 to 22 December	School holidays begin; arrivals build each day	Still fair value; choose now, not later
About 23 December to 1 January	Peak: full hotels, set-menu dinners, heavy traffic	Highest rates of the year; minimum stays are common
First days of January	Peak continues, then eases after the first week	Stay on if you can’t avoid late December

Two groups arrive at once in the last ten days. International visitors come for Christmas and New Year, and Indonesian families come for the school break. Hotels know it, and many add compulsory gala dinners and minimum stays of several nights.

Christmas itself is low-key. Bali is mostly Hindu, so the day is a celebration for visitors: hotels and restaurants put on festive menus, and temples, tours and shops carry on as usual. New Year’s Eve is the big night, with fireworks along the south coast and long traffic jams before and after midnight.

Balinese festivals follow their own calendars, so they don’t fall on fixed December dates. Galungan and Kuningan come round every 210 days, and Nyepi, the day of silence, is usually in March. If one lands during your stay, expect decorated streets and some temple road closures.

If your dates are flexible and you want warm weather with less rain, compare the options in our guide to the best warm-weather destinations in December. And if you must fly in the last week, read how to prepare for flight delays in December first.

What to Do in the Rain: 9 Things That Work in December

This section sorts activities by how well they survive the weather. The short version: culture, food and wellness are barely affected; open-water and summit activities are a gamble.

Activity	December verdict	How to do it
Rice terrace walks (Tegallalang, Jatiluwih, Sidemen)	Good	Start by 8 am; wear shoes that grip
Temples (Tanah Lot, Uluwatu, Tirta Empul)	Good	Mornings; carry a sarong and a rain jacket
Waterfalls	Good with care	Full and loud; skip swimming after heavy rain
Cooking classes, spas, yoga	Very good	Book for the afternoon rain window
Museums and craft villages around Ubud	Very good	Ideal wet-day plan
Surfing	Good on the east coast	Breaks near Sanur, Nusa Dua and Keramas; west coast is onshore
Snorkelling and diving	Mixed	Visibility drops near river mouths; Amed and Tulamben are the safer bet
Mount Batur sunrise hike	A gamble	Cloud often hides the view; trails are slippery
Day trips to Nusa Penida	A gamble	Rough crossings; go only on a calm forecast

Waterfalls deserve a line of their own. They are at their most powerful in December, but the water turns brown after a storm and currents in the pools are stronger than they look. Go for the view, and keep to the marked paths.

Divers should adjust their hopes. Manta rays are seen around Nusa Penida in most months, but the ocean sunfish season is in the dry months, and run-off cuts visibility near the main island. The north-east coast, with its shore dives and wreck, is the most reliable choice.

Two pieces of paperwork are worth doing before you fly. Foreign visitors pay a one-off tourist levy of IDR 150,000 per person, which you can settle online through the official Love Bali website, the provincial government’s portal. Most nationalities also need a visa; check the Indonesian immigration service’s e-visa site for the rules that apply to your passport.

Two Routes That Work With the December Weather

This section gives you two ready-made plans. Both put the sea first, when you’re freshest and the forecast is easiest to read, and both keep long drives to the mornings.

Route 1: ten days, sea first, then green

Route 2: seven days over Christmas or New Year

Pick one base and stay put. Moving hotels in peak week costs you a day in traffic each time. Take four nights in Sanur or Nusa Dua for the beach, then three in Ubud, and travel between them before 10 am.

Reserve your Christmas and New Year’s Eve dinners when you book the room, and ask the hotel whether a gala dinner is compulsory. It often is, and it can add a large amount to the bill.

When NOT to Go, and the Better Month If You Want X

This section is the honest part. December suits a certain kind of trip and frustrates others. You can also check any country and month with our free tool, or see the wider picture on our when not to go page.

If you want…	December is…	Better month
Reliable beach days and dry weather	A poor fit	May, June or September
Surf on the famous west and Bukit breaks	The wrong season	May to September
Clear-water diving and ocean sunfish	A poor fit	July to October
A volcano sunrise with a view	A gamble	May to September
The lowest prices and empty sights	Good only before the 20th	Late January to March, with rain
Dry weather without peak crowds	Not possible	May, June or September
Green terraces and full waterfalls	A good fit	December to March
A tropical Christmas or New Year party	The right month	No better choice

Skip late December altogether if crowds and traffic spoil a trip for you. The island’s roads were not built for peak-week volumes, and a 20-kilometre drive can take two hours. Our guide on how to avoid crowds while travelling in December has tactics that help, but they can’t fix a full island.

Skip December too if the trip is a once-only honeymoon built around beach photos. The odds of a grey, wet week are real, and no hotel can change that.

5 Common Mistakes People Make in Bali in December

This section covers the errors that even repeat visitors make in the wet months.

1. Booking a west-coast beach hotel for the swimming

The photos were taken in July. In December the sea in front of Seminyak or Canggu is often rough, and the sand may be strewn with debris. If the sea matters to you, sleep in Sanur or Nusa Dua and visit the west for dinner.

2. Planning sunset for every evening

Late afternoon is when rain is most likely. Plan one or two sunset outings and treat a clear one as a bonus. Put your fixed plans in the morning instead.

3. Packing an umbrella and cotton

Storm gusts turn umbrellas inside out, and cotton never dries in 80 per cent humidity. A light rain jacket and quick-dry fabrics do the job better and weigh less.

4. Trusting the boat timetable

Fast boats to the Nusa islands and beyond run in most conditions, but crossings get rough and services are sometimes cancelled. Never book an island return for the same day as your flight home.

5. Leaving Christmas week to the last minute

By early December the good-value rooms for the 23rd onwards are gone, and what’s left is priced for people with no choice. Book that week months ahead, or move your trip a fortnight earlier.

Bali in December: FAQ

The Bottom Line

Bali in December is a good trip for early risers who choose their dates and their coast with care: go in the first three weeks, sleep in Sanur or Nusa Dua, and give the afternoons to the rain. Your next step is to fix your dates, then book the base that matches them.
