BALI WEATHER IN DECEMBER
– Peak Wet Season · Christmas & New Year · Highest Prices of the Year –
December brings heavy rain, yet it’s still one of Bali’s busiest and priciest months, driven by Christmas and New Year. Rain rarely deters the festive crowds.
December at a Glance
What to Expect in December
December sits at the heart of Bali’s wet season, and it shows. Rain is a near-daily presence, arriving most often in the afternoon or evening as a short, heavy downpour rather than an all-day drizzle. Mornings still frequently start bright and clear, which is when most outdoor plans should be made. By the back half of the month, storms can occasionally settle in for longer stretches, sometimes a full day.
Temperatures hold at 25-30°C during the day, cooling only slightly to 23-25°C at night. Humidity climbs to around 85%: the highest of the year, which makes December feel like the muggiest month on the island even though the temperature readings themselves aren’t the year’s highest.
Rainfall increases further from November, averaging around 220-270mm across 18-20 rainy days. December sits among Bali’s three wettest months alongside January and February, with January typically taking the title of wettest overall. When the rain falls, it’s usually intense but short-lived, 20 minutes to a couple of hours, though multi-day spells become more common as the month progresses.
Despite the rain, December is Bali’s busiest and highest-priced month of the year. Peak season specifically runs from around 23 December to 6 January, when Christmas and New Year visitors, alongside Indonesian and Australian holidaymakers, push hotel rates, restaurant bookings, and traffic to their annual highs, with some reports of prices tripling compared to the quieter first half of the month. The first three weeks of December are calmer and noticeably better value than the holiday fortnight itself.
Weather by Area
As in November, December’s rain isn’t evenly distributed across the island, and with the added factor of holiday crowds, where you base yourself matters even more this month.
- Canggu & Seminyak (West Coast) — warm and humid at 26-30°C, with regular afternoon or evening showers that are generally short-lived. Mornings usually start clearer, with rain developing later in the day, which can interrupt beach plans more than in November.
- Ubud (Central Highlands) — cooler at 22-26°C, with misty mornings and rain that lasts longer and arrives earlier than on the coast. Some trekking trails become genuinely slippery this month.
- Kintamani (Mountain / Caldera) — the coolest and wettest area covered here, with heavier, more prolonged rain spells than November and chilly highland nights.
- Uluwatu & Nusa Dua (Bukit Peninsula) — moderate rainfall with the limestone terrain’s fast drainage still working in December’s favour — sun often returns quickly between showers. Expect warm temperatures around 26-29°C, though sea conditions vary with the wind.
- Sanur & the Nusa Islands (East Coast) — similar conditions to the Bukit Peninsula, with warm days around 26-29°C and afternoon rain. Sanur and Nusa Dua’s sheltered, reef-protected beaches remain among the calmest and clearest swimming options on the island this month.
Temperature & Comfort
Daytime temperatures of 25-30°C paired with December’s peak humidity make the middle of the day feel noticeably heavier than the dry season, even on the days when rain never falls. Evenings cool only slightly, to 23-25°C on the coast. Highland areas: Ubud and especially Kintamani, run several degrees cooler, and a light jacket earns its keep on an evening in the hills.
Rainfall & Sunshine
Expect around 18-20 rainy days through the month, with rainfall totalling roughly 220-270mm, noticeably more than November’s 150-190mm. Sunshine still averages around 7 hours daily; December’s rain comes in concentrated bursts rather than persistent grey skies, so sunny mornings remain common even in a wet month. UV stays strong whenever the sun does appear.
Surf Conditions
Seas turn rougher and more wind-affected in December, particularly along the south and west coasts. Seasonal debris carried by ocean currents and onshore winds can wash up on Kuta, Seminyak, and Canggu’s beaches, a pattern that typically continues into February. Diving visibility drops with the increased runoff and chop, though sheltered sites like Tulamben and Amed remain workable.
Surf follows the same wet-season pattern established in November: the NW monsoon keeps the east coast: Keramas, Sanur Reef, Green Bowl, and Nusa Dua’s reef breaks, firing fairly consistently through December, typically in the 3-6 foot range. The Bukit’s west-facing breaks are less reliable than in the dry season but can still deliver on wind-lull mornings. For swimming rather than surfing, Nusa Dua and Sanur’s sheltered, reef-protected beaches stay calmer than the west coast even in December’s rougher conditions.
Crowds & Prices: Is December a Good Time to Visit Bali?
December is Bali’s central paradox: its wettest stretch of the year is also its most in-demand. It’s a genuinely great time to visit for festive atmosphere, nightlife, and family holidays, but it rewards planning. Book flights, villas, and New Year’s Eve tables months ahead, especially for the 23 December to 6 January window, when rates hit their annual peak and popular restaurants and beach clubs sell out completely.
If budget or crowds matter more than the holiday buzz, aim for the first three weeks of December, the weather is identical to the peak fortnight, but prices and crowds are markedly lower. If wall-to-wall sunshine is the priority, December will disappoint regardless of timing; that’s simply not what this month offers. What it does offer is Bali at its most alive.
December’s Daily Weather Rhythm
December’s rhythm follows the same rain-aware logic as November, with one difference: back-half-of-month storms can run longer, so it pays to build in more flexibility as Christmas approaches.
Early Morning: 6:00 AM to 10:00 AM
Still the most reliable window of the day. Temple visits, sunrise viewpoints, and dive departures belong here, skies are usually at their clearest before the day’s cloud starts building. This window gets busier than November’s as holiday crowds arrive, so an early start also means beating the day-trip traffic.
Late Morning to Early Afternoon: 10:00 AM to 2:00 PM
Cloud builds over the highlands from mid-morning, though the coast often stays dry into early afternoon. A workable window for the beach or a pool day, but keep plans loose, December’s showers can arrive with less warning than November’s.
Afternoon: 2:00 PM to 6:00 PM
The highest-risk window for rain, and in December the showers are more likely to run long or repeat. This is the month to fully embrace the indoor backup plan: a spa afternoon, a long lunch, a museum visit, or simply riding it out at a covered beach club.
Evening: 6:00 PM – Late
Most evenings clear enough for dinner reservations and beach club events, though December’s storms occasionally extend past sunset, worth checking the forecast before committing to an outdoor NYE table. When skies do clear, the combination of December’s clean post-rain air and busy social calendar makes for some of the best evenings of the year.
December at The Forge means full house energy: cold craft beers and Bintangs, world sport across every timezone, and a kitchen running full pub classics right through the Christmas and New Year rush. Covered seating means the rain is never a reason to skip your table. Given the season, booking ahead matters more this month than any other. Book your table: forgebali.com/reservations.
Best Things to Do in Bali in December
December activities split into two categories: the outdoor essentials that need a morning slot, and the festive, indoor, or rain-proof options that make December worth visiting despite the weather.
Festive Season & Nightlife
- Christmas dinners and beach club events: Seminyak, Canggu, and Uluwatu’s restaurants and beach clubs run full festive programming through the holiday fortnight; book well ahead
- New Year’s Eve parties: Canggu, Seminyak, and Kuta-Legian host the biggest beach club countdowns with international DJs and fireworks; Ubud and Sanur offer quieter, more family-friendly alternatives
- Denpasar Festival (Denfest): a genuinely local counterpoint to the coast’s party scene, with traditional performances, food stalls, and craft markets in the capital
Culture & Temple Ceremonies
- Temple odalan ceremonies: December sees a steady run of temple anniversary ceremonies across the island; ask your accommodation about any happening nearby
- Tirta Empul: the holy spring temple remains a reliable half-day trip regardless of rain, since the ritual bathing happens outdoors in flowing water
- Ubud’s art markets, galleries, and Royal Palace, a dependable rainy-afternoon option in the cultural heart of the island
Diving & Snorkelling
- Tulamben (USAT Liberty Shipwreck): a sheltered, boat-free shore dive that stays workable even when conditions elsewhere are rough
- Amed: Bali’s calmest east coast base for diving and snorkelling, protected from west-coast wind and swell
- Nusa Penida (Manta Point): manta rays remain present, though crossings and visibility are more weather-dependent than in the dry season
Note: December’s rain and chop reduce underwater visibility island-wide; ask your operator about conditions before booking multi-day dive trips
Surfing: East Coast Still Firing
- Keramas: the wet season’s most consistent break, with the NW monsoon keeping conditions offshore through December
- Green Bowl & Sanur Reef: reliable alternatives when the west coast is blown out, suited to intermediate and advanced surfers
- Nusa Dua reef breaks: sheltered on the Bukit’s leeward side, a solid option across ability levels
Note: December’s swells can be messier than November’s; check forecasts closely and consider a local guide for east coast breaks you don’t know well
Wellness, Spas & Indoor Culture
- Ubud’s spa and yoga scene: the island’s best rain-day retreat, especially valuable during December’s longer storm spells
- Cooking classes in Ubud or Seminyak: a genuinely useful way to fill a rained-out afternoon
- Museums and galleries: the Neka Art Museum and ARMA in Ubud remain excellent, weather-proof half-days rains set in
Nature & the Green Season
- Jatiluwih and Tegallalang rice terraces: at their lushest and greenest by December, though muddy underfoot after rain
- Waterfalls (Tegenungan, Gitgit, Aling-Aling), running at full flow; footing can be slippery, so sturdy shoes matter more than usual
Note: Mount Batur and Mount Agung treks are not recommended in December: trails are muddy, visibility is poor, and some operators pause tours entirely during the wettest weeks
Beach & Coastal Life
- Nusa Dua and Sanur: the calmest, clearest swimming beaches in December’s rougher sea conditions
- Beach clubs with covered seating: essential rather than optional this month; check before booking a fully open-air table
- Jimbaran Bay seafood dinner: an evening activity that continues largely unaffected by afternoon rain patterns
Events & Festivals in December
December’s calendar is Bali’s most festive of the year, anchored by Christmas and New Year but backed by a strong run of local cultural events.
Christmas Day (25 December: Island-Wide)
A national public holiday widely celebrated across Bali’s tourist areas. Major beach clubs and resorts in Seminyak, Kuta, and Canggu run dedicated Christmas events and festive dinners, while Ubud keeps things more understated with decorated streets and cafes.
Pandawa Beach Festival (25 December 2026: Pandawa Beach)
A festive stage event at Pandawa Beach on Christmas Day itself, confirmed on Bali’s official 2026 provincial events calendar (reported consistently across Indonesia’s major news outlets), with performances and activities for holiday crowds along one of South Bali’s most striking clifftop-flanked beaches.
Denpasar Festival / Denfest (Late December: Catur Muka, Denpasar)
Bali’s capital city’s biggest annual cultural celebration, held around the Catur Muka Statue at Jl. Gajah Mada. Traditional dance, gamelan, wayang kulit shadow puppetry, fashion shows, craft stalls, and a dedicated culinary festival run over several days. Exact dates shift slightly year to year: recent editions have run anywhere from 20 to 29 December, so check closer to your trip. Free and open to the public, and a genuinely local counterpoint to the coast’s festive scene.
Bali Rockin’ Blues Festival (December: Mertasari Beach, Sanur)
A beachfront rock and blues music festival blending Indonesian and international acts, confirmed on Bali’s official 2026 events calendar with a December staging at Sanur’s Mertasari Beach. Expect a relaxed, family-friendly atmosphere with food stalls and a cultural marketplace alongside the music. Exact date to be confirmed closer to the event.
New Year’s Eve (31 December: Island-Wide)
Bali’s biggest single night of the year. Seminyak, Kuta-Legian, and Canggu host massive beach club countdowns with international DJs and fireworks; Uluwatu’s clifftop venues offer a more scenic alternative. Ubud and Sanur run quieter, more family-friendly celebrations. Every restaurant, hotel, and beach club runs a special programme, book months ahead for anything near the coast.
What to Pack for December in Bali
Clothing Essentials
- Lightweight, quick-drying clothing: essential in December’s peak humidity; technical or travel fabrics outperform cotton and linen
- A proper rain jacket or poncho: more reliable than an umbrella once December’s wind picks up
- Light layer or hoodie: useful for cooler evenings in Ubud and Kintamani
- Closed-toe shoes with good grip: temple steps, rice terrace paths, and waterfall trails get genuinely slippery this month
- One smart-casual or festive outfit: for Christmas dinners, beach club events, and New Year’s Eve
- Sarong: required for temple visits; inexpensive and available everywhere locally
Sun & Protection
- SPF 50+ sunscreen: UV stays strong on December’s frequent sunny mornings
- Wide-brimmed hat and sunglasses: for the mornings that start clear, which is most of them
- A proper umbrella or poncho: for the afternoon showers that are now a near-daily feature
- Waterproof phone pouch or dry bag: genuinely useful for boat trips, beach days, and NYE nights out
Activity-Specific
- A 2-3mm shorty wetsuit or rash guard: for surf sessions in the wet season’s slightly cooler, choppier water
- Reef-safe sunscreen: for diving and snorkelling days
- Sturdy sandals or trekking shoes: for rice terrace walks and waterfall visits, where grip matters more than in the dry season
- A dry bag for electronics: worth keeping accessible if you’re out and about through variable weather
Health & Comfort
- Insect repellent: standing water from near-daily rain increases mosquito activity; apply at dawn and dusk
- Basic rehydration or electrolyte sachets: helpful given December’s peak humidity
Best Areas to Stay in December
With December combining wet-season rainfall and peak-season crowds, where you base yourself affects both how much rain you notice and how easily you can move around during the busiest weeks of the year.
Bukit Peninsula / Uluwatu & Nusa Dua
The Bukit’s fast-draining limestone terrain and Nusa Dua’s sheltered, reef-calmed beaches make this the most weather-resilient base for December, both for rainfall and for the rougher seas affecting the west coast. Combined with a scenic, slightly less chaotic New Year’s Eve scene than Seminyak, it’s a strong all-round pick.
Best for: travellers prioritising calmer swimming, surfers chasing the east coast season, and anyone wanting a more scenic NYE.
Seminyak / Petitenget
Bali’s festive headquarters in December: the highest concentration of Christmas and New Year’s Eve events, plus the dining and nightlife density that makes riding out an afternoon shower easy. Book restaurants, beach clubs, and The Forge well ahead for the 23 December to 6 January window.
Best for: travellers who want to be at the centre of Bali’s festive season.
Ubud
December’s rice terraces and jungle are at their most lush, and Ubud offers a genuinely quieter alternative to the coast’s NYE crowds and traffic. Expect more rain and mistier mornings than the coast, with some trekking trails affected.
Best for: travellers prioritising a calmer, cultural December away from the coastal party scene.
Sanur
Calmer, more sheltered seas than the west coast even in December’s rougher conditions, plus a family-friendly New Year’s Eve scene and the Bali Rockin’ Blues Festival on the calendar. A relaxed, distinctly local-feeling base for the festive season.
Best for: families, first-time visitors, and travellers wanting festive atmosphere without the Seminyak-scale crowds.
Ring in the new year the way Bali's regulars do: cold beers, world sport on every screen through the day, and a full festive programme as midnight approaches. December is our busiest month of the year, so bookings for Christmas Day and New Year's Eve tables should go in well ahead. Book your table: forgebali.com/reservations.
December in Bali: Practical Tips
Timing Tips
- The first three weeks of December offer the same weather as the holiday fortnight at a fraction of the price and crowd: worth prioritising if your dates are flexible
- Book flights, villas, and NYE tables months ahead for the 23 December to 6 January window, this is Bali’s single busiest stretch of the year
- Denpasar Festival and Bali Rockin’ Blues Festival dates shift year to year: confirm exact dates closer to your trip if you want to plan around them
Managing the Rain
- Build a flexible afternoon into each day, especially from mid-December onward, storms can run for hours rather than clearing quickly
- Keep rain gear accessible rather than packed away: December’s showers can arrive with less warning than earlier in the wet season
- Allow extra transfer time around the holiday fortnight: heavy rain combined with peak-season traffic can significantly slow the Seminyak-Canggu-Uluwatu corridor
Health & Safety
- Sea conditions are rougher and currents stronger in December: stick to patrolled beaches like Nusa Dua or Sanur if you’re not a confident ocean swimmer, and always follow lifeguard flags
- Dengue risk remains elevated through the wet season: use repellent consistently, especially at dawn and dusk
- Mount Batur and Mount Agung treks are not recommended this month: check with your accommodation before booking any highland hike
Budget Management
- December rates climb sharply during the 23 December to 6 January window, with some reports of prices tripling compared to early December for the same properties
- Early December offers meaningfully better value: the same weather at low-season-adjacent rates
- Book NYE dinners and beach club tables as early as possible: popular venues sell out weeks, sometimes months, in advance
