December Weather in Detail
December sits deep inside the cool dry season that runs from November through February. Across Laos, the rain is gone. Relative humidity drops to 60-65% in the north (compared to 85%+ in August). Skies are mostly clear with occasional high cloud. The temperature pattern is what makes December special compared to March-April: nights are genuinely cool, days are warm but not punishing.
Specifically, expect:
- Luang Prabang (north): 10-14°C at dawn, 26-28°C by 2pm. Bring a light fleece or hoodie for early morning alms-giving walks and riverboat evenings.
- Vang Vieng (central): 12-16°C at night, 28-30°C in the afternoon. Slightly warmer than Luang Prabang due to lower elevation.
- Vientiane (capital): 14-18°C at night, 28-30°C by day. Drier and cooler than any month between March and October.
- 4000 Islands (south, Si Phan Don): 18-22°C at night, 30-32°C by day. The warmest region in December, also the driest. See our 4000 Islands guide for food, stays, and getting there.
Rainfall: roughly 5-15mm total for the month, almost all of it in one or two brief pre-dawn showers that evaporate by sunrise. You won’t need a raincoat. You will need sunscreen and a warm layer for night buses and riverside hostels.
Crowds and Tourism Pressure
December is high season, full stop. You’ll see it in three concrete ways:
- Hostel dorms fill by mid-afternoon. Luang Prabang and Vang Vieng hostels are frequently booked out 2-3 weeks ahead for the Christmas-New Year window (roughly Dec 20 to Jan 5). Outside that week, you can mostly walk in.
- Slow boats get booked out. The Huay Xai to Luang Prabang two-day Mekong slow boat is the poster activity for December, and the morning departures sell out a week or more ahead in peak weeks.
- Domestic flights get pricey. Vientiane to Luang Prabang and Pakse flights run ₹2,000-₹3,000 (~$20.75-$31.12) higher per leg in December compared to late October.
The crowd mix is mostly European (German, French, Dutch) and East Asian (Chinese, Korean, Thai) holiday-makers, plus a smaller American and Australian contingent. Indian backpackers are noticeably fewer than in Vietnam or Thailand, which means Indian-run restaurants are concentrated in Luang Prabang, Vientiane, and 4000 Islands, not Vang Vieng.
Pros and Cons
Pros:
- Best weather of the year: cool dry days, clear skies, zero mud. See our month-by-month guide for the full comparison.
- Slow boat on the Mekong is at its safest and most scenic water level.
- All major sights and routes are open (no monsoon closures on Route 13 or the Bolaven Plateau).
- Christmas and New Year atmosphere in Vientiane and Luang Prabang if you want the social peak.
- Indian food options in Luang Prabang and 4000 Islands are at their busiest and most staffed.
Cons:
- Peak pricing across flights, hostels, and tours.
- Luang Prabang hostel beds are scarce and the top of the canonical dorm range for almost the entire month.
- Slow boats and Luang Prabang city tours need 1-2 week advance booking.
- Christmas and New Year week (Dec 22 to Jan 2) brings the largest crowds and the highest prices, including mandatory gala dinners at many riverside restaurants if you want a reservation.
- December is also northern Laos’ burn-off (slash-and-burn) season, so early mornings can have smoke haze that affects sunrise visibility over the Mekong. Travellers in late November and early January sometimes report clearer skies than mid-December for that reason.
What to Pack Specifically for December Laos
December packing is dry-season packing. You won’t need a poncho or dry bag. You will need layers. See our full Laos packing checklist for the complete list.
- Light fleece or zip hoodie (10-16°C mornings in Luang Prabang and Vang Vieng).
- One warm layer for slow boats and night buses, which drop to 12-15°C with the breeze.
- Quick-dry t-shirts for 28°C afternoons (laundry dries in 2 hours, fastest of the year).
- Long pants or leggings for cool evenings and for visiting temples, which require covered knees and shoulders.
- Sunscreen SPF 50+ (UV is high even at 25°C in dry-season Laos).
- Refillable water bottle (humidity is low and you’ll drink more than you think).
Skip: raincoat, heavy boots, mosquito repellent concentrations. Skip the ultralight travel umbrella. If you’re heading to 4000 Islands, pack a swimsuit for the Mekong and a rashguard for kayaking.
December Costs vs Shoulder vs Monsoon
December is peak pricing across every category. Here’s how it compares to the late-November shoulder and the August monsoon low.
| Item | Peak (December) | Shoulder (Late November) | Low (Monsoon) |
|---|---|---|---|
| Flight from India (round trip) | ₹32,000-₹42,000 (~$331.94-$435.67) | ₹24,000-₹30,000 (~$248.95-$311.19) | ₹18,000-₹22,000 (~$186.71-$228.21) |
| Domestic flight VTE-LPQ | ₹6,500-₹9,000 (~$67.42-$93.36) | ₹5,000-₹7,000 (~$51.87-$72.61) | ₹4,000-₹5,500 (~$41.49-$57.05) |
| Luang Prabang dorm (per night) | ₹475-₹755 (~110,000-175,000 LAK or ~$4.92-$7.83) | ₹388-₹647 (~90,000-150,000 LAK or ~$4.03-$6.71) | ₹302-₹475 (~70,000-110,000 LAK or ~$3.13-$4.92) |
| Vang Vieng dorm (per night) | ₹388-₹690 (~90,000-160,000 LAK or ~$4.03-$7.16) | ₹324-₹518 (~75,000-120,000 LAK or ~$3.36-$5.37) | ₹259-₹432 (~60,000-100,000 LAK or ~$2.69-$4.48) |
| Slow boat Huay Xai to LPQ | ₹561-₹647 (~130,000-150,000 LAK or ~$5.82-$6.71) | ₹561-₹647 (~130,000-150,000 LAK or ~$5.82-$6.71) | ₹475-₹561 (~110,000-130,000 LAK or ~$4.92-$5.82) |
| Kuang Si Falls entrance | ₹129 (~30,000 LAK or ~$1.34) | ₹129 (~30,000 LAK or ~$1.34) | ₹129 (~30,000 LAK or ~$1.34) |
The biggest single price differential is the international flight. Indian-origin fares from Delhi, Mumbai, and Bengaluru bump up ₹8,000-₹12,000 (~$82.98-$124.48) round trip from late November to mid-December. Domestic VTE-LPQ runs ₹1,500-₹2,500 (~$15.56-$25.93) higher per leg. Dorm beds go up about 15-25% from shoulder. Tours and slow boat tickets hold closer to flat pricing year-round.
Getting Connected
December is the easiest month to stay connected: no rain to interfere with signal, every cell tower running on generator backup is dormant, and the dry-season power grid is stable. Pick up a Unitel or Tplus SIM at Wattay Airport (Vientiane) or Luang Prabang Airport for ₹259-₹345 (~60,000-80,000 LAK or ~$2.69-$3.58) with 30 days of data. Coverage is excellent in all four hub cities (Vientiane, Vang Prabang, Vang Vieng, Pakse) and decent along Route 13 and the Mekong. For shorter trips, Get Nomad eSIM gives you data on landing without a passport swap at the kiosk.

FAQ
Is December the best month to visit Laos? Yes, alongside January and February. December has the best weather for slow boats, trekking, and the Bolaven Plateau loop, and zero rain anywhere in the country.
How cold does it get in Laos in December? Luang Prabang and Phongsali drop to 8-12°C before sunrise, the coldest the country gets all year. Vientiane and Vang Vieng stay milder at 14-18°C at night.
Is Luang Prabang crowded in December? Yes, especially over Christmas and New Year. The week before Christmas and the week after New Year are noticeably calmer if you want the town with fewer tour groups.
What is the That Luang Festival? Laos’ largest religious festival, held at That Luang stupa in Vientiane. It typically runs for a week in late November but routinely spills into the first week of December. Expect processions, markets, and a major fair around the stupa.
Can I do the slow boat from Huay Xai to Luang Prabang in December? Yes, December is the best month for it. Water levels are moderate, skies are clear, and the Mekong is calm. Book at least a week ahead for the Christmas-New Year week.
Is Christmas a big deal in Laos? For tourists, yes (riverside dinners, NYE fireworks in Vientiane). For locals, no. Most cafes and guesthouses run a Christmas menu, but expect it to feel staged for the foreign crowd.
Subodh’s Take
December is the right month to go if your dates are fixed and you want the best weather with zero rain risk. It’s the wrong month to go if you’re flexible, because you’ll pay 25-40% more for almost everything compared to a November shoulder week that has nearly identical weather. If you can shift your trip by even 10 days on either side, do it. If you can’t, book hostels and the Huay Xai slow boat at least three weeks out, particularly for the Dec 22 to Jan 2 peak window.
