## The short answer
For December 2026, start by choosing between the north’s cooler weather and an Andaman beach stay. The historical averages favour both over the lower Gulf for a drier trip. Christmas and New Year add a separate decision: check the room and transport terms before fixing the route.
* **Beaches:** Pick Phuket, Krabi or Koh Lipe for the Andaman beach season as it starts, or Hua Hin, Pattaya and Koh Chang for the driest December averages.
* **Cool weather and culture:** Head to Chiang Mai or Bangkok for usually clear skies and manageable heat.
* **Christmas and New Year:** Book your room and key transport early, with cancellation terms you can accept. Check for a minimum stay or a compulsory gala dinner before paying.
* **Hold off on:** The lower Gulf islands like Koh Samui, which are often still wet and rough in December.
## December weather at a glance
(An interactive table or map is on the web page: .)
On average the Andaman coast gets about 130 to 140 mm of rain in December, much less than in November, and January is drier again. Over in the Gulf, Koh Samui and Koh Phangan average about 260 mm, the tail end of their rainy season, so heavier downpours and choppy water are more likely there. These are historical monthly averages, not a forecast: before a beach or boat day, check the Thai Meteorological Department's [7-day forecast](https://www.tmd.go.th/en/forecast/sevenday), [shipping forecast](https://www.tmd.go.th/en/forecast/shipping) and [weather warnings](https://www.tmd.go.th/en/warning-and-events/warning-storm).
## Christmas and New Year 2026
* **Gala dinners:** Some resorts build a festive gala dinner into a holiday stay, which adds a fixed cost. Renaissance Pattaya's New Year's Eve 2026 package, for example, includes a gala dinner on 31 December and charges extra guests for it. Check your rate's terms for 24 and 31 December.
* **New Year's Eve countdowns:** Bangkok hosts big street parties on December 31 outside major malls like CentralWorld.
* **Full Moon Party:** The [Haad Rin business-maintained calendar](https://www.fullmoonpartythailand.com/dates) lists a New Year's Eve edition on 31 December 2026, an expected date checked 19 October 2026. See our [Full Moon Party guide](https://trip4am.com/guides/full-moon-party-koh-phangan-where-to-stay/) for the source and base choices, and reconfirm the event before booking.
* **Minimum stays:** Some hotels set a minimum stay over the holidays; that Renaissance Pattaya package needs two nights covering 31 December and 1 January. The minimum varies by hotel, so check it on the rate you book.
## Phuket
(An interactive table or map is on the web page: .)
Phuket is a practical first stop if you want direct flights, beaches and plenty of places to eat. December is much drier than November on average, though the sea still changes from day to day. Choose a west-coast beach base for time on the sand, or Phuket Town for food and the Old Town.
**From a beach or town base:**
* **Island hopping:** Take a speedboat out to Phang Nga Bay to see the limestone karsts jutting out of the water.
* **Old Town:** Walk through the historical streets to see Sino-Portuguese architecture and eat local Hokkien noodles.
* **Night markets:** Grab street food at the Sunday Walking Street Market when the sun goes down.
* **Viewpoints:** Drive up to the Big Buddha for wide views across the southern bays.
**Choose your base:** Pick Kata or Karon if you want long beaches and family resorts, or choose Phuket Town if you prefer culture over sand.
For fewer transfers within Phuket, choose a base near the beach or town you plan to use most. Allow for peak-season traffic.
## Krabi
(An interactive table or map is on the web page: .)
Krabi averages about 139 mm of rain in December, compared with about 232 mm in November in the dataset shown above. Keep a spare day for a boat trip: the monthly average cannot tell you whether your crossing will run. Ao Nang and Railay make different bases, depending on how much of the trip you want to spend beside the cliffs.
**Plan around the boat trips:**
* **Railay's cliffs:** Hire a longtail boat to reach this peninsula for rock climbing beside the beach.
* **Island tours:** Compare trips to the Phi Phi Islands, leaving room for a weather cancellation.
* **Jungle pools:** See the Emerald Pool (Sa Morakot), a large green pool with a small cascade in the Khao Pra-Bang Khram Wildlife Sanctuary. The hot spring waterfall at Khlong Thom (Namtok Ron) and the Khlong Thom salt hot springs are separate sites, so check which ones a day tour includes; the [Tourism Authority of Thailand](https://www.tourismthailand.org/Articles/10-things-to-do-in-krabi) lists all three as different attractions. Its 2020 description says the Emerald Pool is swimmable, so check current access and whether swimming is open on the day.
* **Tiger Cave Temple:** Climb the 1,260 steps for a panoramic view of the province.
**Choose your base:** Base yourself in Ao Nang for easy boat access, or choose Railay if you want to wake up next to the cliffs.
If a long beach matters more than boat trips between coves, compare Phuket before fixing your base.
## Khao Lak
(An interactive table or map is on the web page: .)
Choose Khao Lak if your plan centres on beach time and trips to the national parks. It sits on the mainland coast north of Phuket; compare the beach areas before booking, especially if you want restaurants within walking distance.
**Inland or offshore:**
* **Similan Islands:** Compare dive trips to this marine park and confirm which sites your operator plans to visit. Our [national park closures guide](https://trip4am.com/guides/thailand-national-park-closures-2026-27/) has this season's opening date and the sites that stay closed.
* **Khao Sok:** Drive inland to Khao Sok National Park for jungle trekking and boat tours on the huge lake.
* **Quiet beaches:** Walk along Bang Niang or Nang Thong beach.
* **Waterfalls:** Hike the short trail to Ton Chong Fa Waterfall for a cool afternoon dip.
**Choose your base:** Look around Bang Niang if you want a few restaurants nearby, but compare Khuk Khak if you prefer a quieter base.
For late nightlife, compare Phuket before committing to Khao Lak.
## Koh Lipe
(An interactive table or map is on the web page: .)
Way down south near the Malaysian border, tiny Koh Lipe is known for clear water, though visibility depends on the sea on the day. The island is small enough to walk across, though December brings a steady stream of ferries and speedboats.
**Around the island:**
* **House reefs:** Snorkel right off the beach to see coral and tropical fish without paying for a boat tour.
* **Walking Street:** Eat fresh seafood and grab a drink on the main pedestrian strip.
* **Sunset views:** Head to Sunset Beach with a cold drink to watch the day end.
* **Island hopping:** Hire a boat to explore the surrounding uninhabited islands in the marine park.
**Choose your base:** Pick Sunrise Beach for morning light, or choose Pattaya Beach if you want to be steps from the ferry drop-off.
Check the crossing time and operator’s change terms before booking; the boat journey is part of the choice.
## Chiang Mai
(An interactive table or map is on the web page: .)
Chiang Mai suits a December trip built around temple walks, cafes and time in the hills. Evenings and early starts can feel cool, so pack a light layer. Choose the Old City for its temples or Nimman for its cafes before you compare rooms.
**Temples, hills and cafes:**
* **Old City temples:** Walk between centuries-old stupas like Wat Chedi Luang right in the center of town.
* **Doi Suthep:** Drive up the mountain to see the golden temple overlooking the city.
* **Coffee culture:** Spend an afternoon hopping between roasters in the Nimman neighborhood.
* **Weekend markets:** Shop for local crafts at the big Sunday Walking Street.
**Choose your base:** Stay inside the Old City moat for historical charm, or pick Nimman if you prefer modern cafes and digital nomad hubs. Our [Old City or Nimman](https://trip4am.com/guides/chiang-mai-old-city-vs-nimman/) guide compares the two.
For a trip with both hills and beaches, give Chiang Mai its own few days rather than treating it as a stop on the way south.
## Bangkok
(An interactive table or map is on the web page: .)
Bangkok works well for a few days of food, markets and river trips before heading north or to the coast. December is mostly dry and relatively cool on average, but the choice of neighbourhood still matters: check how you will reach the places on your list.
**Build a day around:**
* **River ferries:** Ride the Chao Phraya Express Boat past the Grand Palace and Wat Arun. The Orange Flag boat costs 19 baht for the full route from 5 October 2026, and fares move with diesel prices.
* **Chatuchak Market:** Spend a weekend morning walking through thousands of stalls selling everything imaginable.
* **Chinatown:** Eat your way down Yaowarat Road at night for street food.
* **Skybars:** Grab an evening drink on a rooftop for a clear view of the skyline.
**Choose your base:** Pick Sukhumvit if you want to be right on the Skytrain line, or choose the Riverside for a quieter, more scenic base.
Keep Bangkok brief if beach time matters more to you than markets, food and city sightseeing.
## Koh Chang and Koh Samet
(An interactive table or map is on the web page: .)
These eastern islands are among the driest choices in December on average (Koh Chang about 36 mm), which makes them a practical alternative to the south, though an average does not promise dry days. Koh Samet is a quick hop from Bangkok, while Koh Chang takes more effort to reach but gives you a larger, rugged island.
**On Koh Chang and Koh Samet:**
* **White Sand Beach:** Swim and eat fresh seafood on Koh Chang's most accessible stretch of sand.
* **Jungle hikes:** Trek to Klong Plu Waterfall on Koh Chang for a freshwater swim.
* **Fire shows:** Watch the evening beach performances on Koh Samet's Sai Kaew Beach.
* **Island hopping:** Take a boat trip to the smaller, quieter islands south of Koh Chang.
**Choose your base:** Pick Lonely Beach on Koh Chang if you want backpacker bars, or choose Ao Prao on Koh Samet for a quiet resort feel.
Choose these eastern islands for access from Bangkok. Compare Krabi if the limestone scenery is central to your trip.
## The Gulf islands in December
(An interactive table or map is on the web page: .)
Koh Samui and Koh Phangan are still in their rainy season in December, averaging about 260 mm for the month; Koh Tao averages a little under 200 mm. Expect heavy showers and rough seas on some days. January is much drier on average, but a monthly figure cannot tell you which week will settle, so check the forecast for your dates.
**If you choose the Gulf:**
* **Fisherman's Village:** Walk the Friday night market in Bophut on Koh Samui for street food and souvenirs.
* **Diving:** Take a boat out from Koh Tao, though visibility can be reduced after rough weather.
* **Beach clubs:** Spend a cloudy afternoon at a day club on Koh Samui's north coast.
* **Yoga retreats:** Join a wellness center in Koh Phangan's Sri Thanu area while it rains outside.
**Choose your base:** Pick Chaweng on Koh Samui if you want nightlife regardless of the weather, or choose Koh Tao if you are focused on scuba diving.
Keep the Gulf for a flexible trip: December is still one of its wetter months on average. Compare the Andaman coast if dry beach days are your main priority.
## Booking early: what to know
If your dates include Christmas or New Year, compare the whole trip cost before you pay for the room.
* **Check the room terms:** Look for a minimum stay, a compulsory dinner and the cancellation deadline on your chosen rate.
* **Compare the total:** Check taxes, fees and any festive extras. If a rate is quoted "++", our [guide to Thai hotel prices](https://trip4am.com/guides/thai-hotel-plus-plus-tax-explained/) shows how to estimate the total.
* **Match transport to the room:** Check flights, ferries or sleeper trains for the same dates before committing to a non-refundable stay.
* **Stay flexible:** Look for places with generous cancellation policies if your plans might change.
> Tip: Check the ferry schedules for your dates, read the operator's change and refund terms, and secure your transport before finalizing your hotel reservations.
## How long to stay
Plan for 10 to 14 days to see a good mix of the country without spending your whole trip in transit. Start with three days in Bangkok, fly up to Chiang Mai for four days of cool weather, and finish with a week on the Andaman coast in Krabi or Phuket. To choose between them, see [Phuket or Krabi](https://trip4am.com/guides/phuket-vs-krabi/).
## Frequently asked questions
### Is December a good time to visit Thailand?
Yes, it is one of the most popular months of the year. On average the north and central regions are cool and dry, while the Andaman coast starts its beach season.
### Is it rainy in Koh Samui in December?
Yes, on average. Koh Samui averages about 260 mm of rain in December, still part of its rainy season, so expect heavy showers and rough seas on some days. The monthly figure cannot tell you which days; January is much drier on average. Check the [shipping forecast](https://www.tmd.go.th/en/forecast/shipping) before a ferry day.
### Where is the best beach weather in December?
On average, the Andaman coast and the coast and islands near Bangkok. Phuket, Krabi, Khao Lak and Koh Lipe average about 130 to 140 mm of rain in December, much less than in November, and Pattaya (about 14 mm), Hua Hin (about 27 mm) and Koh Chang (about 36 mm) are drier still. That is a historical pattern, not a forecast: check the forecast for your dates and confirm boat trips with the operator.
### How early should I book for New Year?
Once your dates are settled, compare rooms and key transport together. For Christmas and New Year, check minimum stays, gala-dinner charges and cancellation deadlines before paying; a room price alone may not be the trip’s full cost.
