Is December Right for You?
Weigh the advantages and considerations before booking
- + December lands squarely in Laos's dry-season sweet spot. The monsoon taps shut in late October, and by December the air has shed the waterlogged weight that drags through the wet months. Over Luang Prabang the sky snaps into sharp blue by 8 AM, and the Mekong slips low enough to expose pale sandbars and slick rock shelves that stay submerged half the year. Northern highland trails around Phongsali and Luang Namtha are dry, firm underfoot, and the valley mist caught between karst peaks burns off by mid-morning, delivering visibility you never see from June through September.
- + Temperatures finally behave like Southeast Asia on its best behavior. Vientiane afternoons peak around 28°C (82°F) with humidity hovering near 65%, a clear drop from the 85%+ that soaks the capital from May onward. Above 1,000 m (3,280 ft) in the northern mountains, mornings dip to 8-10°C (46-50°F), cool enough that Hmong villagers in padded jackets huddle around small fires. For anyone used to dripping through Bangkok or Phnom Penh, the relief is instant.
- + December flips Laos food culture into cool-season gear. Sellers along Luang Prabang's morning market on Sisavangvong Road wheel out jaew bong, a thick, smoky mash of roasted chili, dried buffalo skin, and padaek (Lao fermented fish paste), pounded fresh in mortars so large two people haul them. Charcoal grills along the Night Market fire up earlier because the air is finally cool enough to stand beside open flame without misery. Sticky rice steams in bamboo baskets everywhere, and that warm, faintly sweet, starchy scent becomes the baseline note of every meal.
- + The Mekong stays navigable yet calm, making December prime time for the two-day slow boat from Huay Xai on the Thai border down to Luang Prabang, roughly 300 km (186 miles) of river framed by teak forest, limestone cliffs, and villages reachable only by water. Water sits low enough for the captain to weave through rapids without worry. Yet high enough to dodge the sandbars that strand boats in March and April. You glide through stretches where the only sounds are the engine, the water, and the occasional rooster calling from an unseen village up the bank.
- − December kicks off peak season, and Luang Prabang feels the increase. The UNESCO-listed old town, about 35 blocks of French colonial and traditional Lao buildings squeezed between the Mekong and Nam Khan rivers, packs tight from mid-December to early January. The dawn alms-giving along the main road, where saffron-robed monks collect sticky rice from kneeling residents, now draws a ring of tourists with telephoto lenses and idling tour buses. The ritual still runs. It remains a living practice. But the tone has changed. If it matters to you, walk three blocks south to the smaller wats where five monks move in silence and no one watches.
- − The northern highlands turn cold enough to shock. Travelers who packed for tropical Southeast Asia land in Phongsali or the Bolaven Plateau and shiver at 6 AM in shorts and a tank top while fog presses against the guesthouse glass. Nighttime temperatures above 800 m (2,625 ft) regularly fall below 10°C (50°F) in December, and heated rooms barely exist outside a few spots in Luang Prabang. Trekking in Luang Namtha province or sleeping in village homestays demands layers, a proper fleece, and at minimum a sleeping bag liner.
- − Rooms in Luang Prabang and Vang Vieng sell out quickly for the Christmas-New Year stretch, and prices jump. What you paid in September can double or triple for the same bed in late December. Booking six to eight weeks ahead for December nights in Luang Prabang isn't overcautious, it's essential if you want any choice. Vientiane feels less pressure. Yet riverside rooms tighten around Lao National Day on December 2nd.
Best Activities in December
Top things to do during your visit
The two-day slow boat down the Mekong sticks in most travelers' memories as the single most vivid thing they do in Laos, and December may be the best month for it. After the monsoon the river runs clear and low, the banks glow green from recent rains while the sky stays dry, and the temperature on deck hovers around 25°C (77°F) with a breeze that makes sitting on wooden benches pleasant instead of the sweat-drenched ordeal it becomes in April. You push off from Huay Xai in the morning, drift through stretches where karst cliffs rise straight from the water like a scroll-painting backdrop, overnight in the river town of Pakbeng, and reach Luang Prabang by late afternoon the next day. The river's scent, earthy, mineral, faintly green, lingers. December's lower water pulls the boat into a narrower channel, closer to the banks, so you catch more detail: fishermen casting nets from wooden pirogues, water buffalo standing chest-deep, children waving from bamboo platforms above the waterline.
Luang Namtha is the launch pad for the Nam Ha National Protected Area, 222,400 ha (549,500 acres) of untouched forest and montane jungle, and December is when the trails come alive. The red earth hardens, rivers shrink to knee-high splashes, and shafts of light slip through the canopy to ignite the tree ferns and dangling epiphytes. Two- and three-day hikes climb between 600, 1,200 m (1,970, 3,940 ft), threading Khmu and Akha villages where you bunk on woven mats in bamboo longhouses and share lam, the day's forest stew of bamboo shoots, river greens, and whatever the hunters bring in. Dawn is crisp enough for misted breath. But by 10 a.m. you're down to one shirt as the trail rises through sun-lit glades. Dry-season birds own the canopy: great hornbills thud overhead and blue-winged pittas flick metallic blue in the understorey.
Thirty kilometres south of Luang Prabang, Kuang Si is the waterfall that broke the internet, and December shows you why. The 60 m (197 ft) cascade spills through a staircase of turquoise limestone pools whose colour looks Photoshopped but is simply calcium carbonate meeting sunlight. Sediment is low, so the blues sharpen, and at 22 °C (72 °F) the water slaps you awake before it feels perfect. Gibbons whoop from the dipterocarp canopy at dawn; a hidden trail curls behind the main drop to the wide limestone lip where the roar fades to a hush. Arrive before 9 a.m. or after 3 p.m. to dodge the tour-bus increase. On your way out, linger at the bear-rescue centre, cool December mornings rouse the Asiatic black bears, sending them climbing and foraging instead of dozing through the heat.
Vang Vieng spent ten years scrubbing off the party grime and rediscovered the landscape that was waiting all along: a rice-paddy valley ring-fenced by karst towers, river caves and spring-fed blue lagoons. December is prime time on the Nam Song: gentle current, lower water that unseals cave mouths, and 26 °C (79 °F) air that lets you paddle for hours. Tham Chang, ten minutes from town, delivers cathedral-size chambers where your torch beam dies before it finds the far wall. Cycle 3 km (1.9 miles) and climb to Tham Phu Kham; inside, a reclining bronze Buddha rests on green-tinged stone, and outside the lagoon is so clear you can count pebbles 3 m (10 ft) down. Tubing still floats along. But December afternoons drift past water buffalo, not booze barges.
Vientiane refuses to shout. It mur is a capital that behaves like a languid country town, and a push-bike at December's 28°C (82°F) is the perfect pace to let it confess its secrets. Roll south along Fa Ngum Road and the Mekong promenade unrolls for 5 km (3.1 miles): dawn tai-chi in Chao Anouvong Park, French shutters flaking paint above Setthathirath Road, and the 1818 cloisters of Wat Si Saket where more than 2,000 ceramic and silver Buddhas stand in hypnotic formation. Pedal north-east and you can be at Patuxai, Laos's concrete nod to the Arc de Triomphe, finished with cement originally donated for an airport runway, then glide on to the golden bulk of Pha That Luang, the national crest, in under 20 minutes. After sunset the riverfront night market ignites: smoke from ping kai, lemongrass-and-fish-sauce chickens, drifts across the road, laap salads detonate with lime and toasted rice powder, and vendors ladle khao piak sen, the milky galangal-scented noodle soup, into bowls big enough to swim in.
Southern Laos lifts abruptly to the Bolaven Plateau, 1,200 m (3,940 ft) above the Mekong, and December is when the coffee cherries turn lipstick-red. Volcanic soil and altitude coax arabica beans that taste of dark chocolate and carry a natural sweetness no sugar can improve. A 200 km (124-mile) loop out of Pakse strings together Tad Fane's twin 120 m (394 ft) falls, permanent mist swirling in the gorge, and the broad, swim-friendly curtain of Tad Yuang where the stone trembles under the water's weight. Daytime highs sit at a crisp 20-24°C (68-75°F) and nights dip to 12°C (54°F), so bring a jacket. In the Laven and Katu villages, bamboo drying beds sag under scarlet cherries and the air carries the popcorn crackle of beans in wood-fired drums. Drive for an hour without seeing another foreign plate and you will understand why this stretch of Southeast Asia still feels like a private discovery.
