December marks the beginning of Chiang Mai’s finest season. The rains have finished, temperatures have dropped to their most comfortable range, and the city’s Old Town, night markets, and surrounding mountains are at their most appealing. This is when Chiang Mai earns its reputation as a winter escape — particularly for visitors from Bangkok and international travellers who want cooler weather alongside Thailand’s cultural heartland.
Weather in December
December is one of Chiang Mai’s driest months. Expect highs of 28–30°C during the day with mornings and evenings significantly cooler — typically 14–16°C in the city and noticeably colder in the hills. Rain is rare: the whole month typically sees fewer than 15mm, spread across two or three brief showers.
The cool season creates ideal conditions for outdoor activity. Trekking, cycling, and motorbike rides through the mountain villages are all far more comfortable than in the humid months of May through October. Night temperatures are low enough that sitting outside in the evening with a beer or coffee feels genuinely pleasant — something that’s not always the case in Bangkok.
One caveat: haze. Agricultural burning begins in the hills around December, and you’ll notice some morning haze, particularly in the first half of the month. It’s nothing like the choking smoke of March and April, but visibility on clear-day mountain views may be reduced. December photography is generally good; March is not.
Things to do in December
Old Town and temple circuit
The cool weather makes December perfect for walking Chiang Mai’s walled Old Town. The classic temple circuit — Wat Chedi Luang, Wat Phra Singh, Wat Chiang Man — is entirely walkable in December conditions without the sweating of high summer. Early mornings are particularly atmospheric: mist clings to the moat, monks collect alms, and the light through the temple grounds is exceptional.
Doi Inthanon National Park
Thailand’s highest peak at 2,565m is one of the best day trips from Chiang Mai and genuinely worthwhile in December. The summit is cool enough to require a jacket — temperatures can reach 5°C after dark and 8–12°C in the morning. The waterfalls are past their peak flow from the wet season but still impressive, and the Hmong hill tribe markets near the summit are active through December.
The park entry fee is 300 THB per person for foreign visitors (as of 2026), plus 30 THB per car or 20 THB per motorbike. The drive from Chiang Mai takes approximately 1.5 hours each way.
Elephant sanctuaries
The ethical elephant sanctuaries in the Chiang Mai area — including Elephant Nature Park (ENP) in Mae Taeng and Elephant Jungle Sanctuary — run year-round, but December is particularly comfortable for the outdoor half-day and full-day programs. Prices start at approximately 2,500 THB per person for a half-day at established sanctuaries. Book at least two weeks ahead for December visits — ENP fills up fast.

Doi Suthep
The hilltop temple that looms over the city is busier in December with domestic Thai visitors on long weekends. Aim for early morning (7–8am) before tour groups arrive, or late afternoon. The cable car/shuttle songthaew system costs around 40 THB each way from the temple parking area; the full hike up the 300+ stairs is manageable in December temperatures.
Night Bazaar and Sunday Walking Street
Chiang Mai’s Night Bazaar (Changklan Road) runs nightly and is at its most atmospheric when the cool evening air makes wandering pleasant. The Sunday Walking Street along Wualai Road is the better of the two weekend markets — more craft-focused, less touristy — and December draws a particularly good selection of vendors.
Christmas and New Year in Chiang Mai
Chiang Mai doesn’t have beach-style Christmas party culture, but it has developed a growing festive scene centred on the Nimman area. One Nimman and the surrounding streets put up Christmas decorations, cafes compete with festive menus, and the rooftop bars along Nimman run New Year countdown events with city views.
For New Year’s Eve, Central Festival (the main mall on Highway 11) hosts a ticketed countdown event with live music. The Nimman area becomes a street party by about 10pm. Compared to Bangkok’s Silom countdown or Phuket’s Bangla Road celebrations, Chiang Mai’s New Year is lower-key and, for many visitors, more enjoyable as a result.
Where to stay in December
December is high season in Chiang Mai. Book accommodation at least six weeks ahead, and two to three months ahead if you want options in the Old Town or Nimman for Christmas and New Year week.
Old Town: Walking distance to temples, best for atmosphere. Mid-range guesthouses start at around 1,000–1,500 THB per night; boutique heritage hotels run 3,000–6,000 THB. The Tamarind Village and 137 Pillars House are the top-end properties here.
Nimman: The city’s creative quarter, lined with independent cafes, gallery spaces, and co-working spots. Popular with digital nomads and younger travellers. Mid-range hotels from 1,200 THB; boutique options at 2,500–4,000 THB.
Riverside (Charoen Prathet area): Quieter, with a cluster of guesthouses and the Night Bazaar nearby. Good value, particularly for longer stays.
Compare hotels in Chiang Mai for December — book the Old Town and Nimman areas 6–8 weeks ahead.
Getting around in December
Chiang Mai is manageable with a combination of red songthaews (shared pickup trucks operating as shared taxis, approximately 30–50 THB per person for city trips), tuk-tuks for short hops, and motorbike or bicycle rental for more flexibility. December brings more traffic to the main roads around the Old Town moat, particularly in the evenings around the Sunday and Saturday markets.
For Doi Inthanon and the northern hill station villages, renting a motorbike (250cc recommended for mountain roads; approximately 250–350 THB/day) or joining an organised day tour (from 900 THB/person) is more practical than public transport.
What to pack for December
The temperature range in December is wider than most visitors expect. Plan for:
- Light layers or a fleece for evenings and early mornings
- Standard summer clothes for midday sightseeing
- Warmer jacket if visiting Doi Inthanon summit or doing overnight trekking
- Closed shoes or sandals with good grip for temple stairs and mountain trails
- Sunscreen — even in the cool season the midday sun is strong
