December is widely considered the best time to visit Thailand, with cooler temperatures, lower humidity, and ideal weather that’s perfect for exploring. Whether you’re dreaming of a tropical Christmas or just want to escape the winter chill back home, Thailand in December offers it all.

However, there’s a catch—this is peak tourist season, so you’ll be dealing with the busiest time of year. If crowds aren’t your thing, consider heading to off-the-beaten-path locations.

Also, keep in mind that while most of Thailand enjoys near-perfect weather, some islands like Koh Samui are still in their rainy season in December. The last thing you want is for your beach days to get washed out!

I’ve spent December in Thailand (as well as most other months). I’ve celebrated Christmas in Pai’s lively bars and watched New Year’s Eve fireworks on Koh Samui’s beaches.

As you plan your holiday to Thailand in December, knowing where to go is crucial for that perfect vacation experience.

Should You Visit Thailand in December?

December is undoubtedly one of the most popular times to visit Thailand, and for good reason. 

The weather is at its prime—cooler temperatures, reduced humidity, and plenty of sunshine make it perfect for beach lounging, temple hopping, and trekking through lush jungles. It’s also the dry season, which means less rain and more reliable conditions for outdoor adventures.

But with all these advantages come a few trade-offs. 

December is peak tourist season in Thailand, which means crowded attractions, busy streets, and higher prices. 

If you’re like me, the idea of navigating through throngs of tourists and paying premium prices for everything can be a bit of a turn-off.

Personally, I prefer to avoid peak season, even if it means risking a little hot weather or the occasional rain shower. There’s something to be said for experiencing Thailand’s beauty without feeling packed in like sardines, and I’m willing to trade a bit of comfort for a more relaxed and affordable experience.

That said, if you’re set on visiting Thailand in December, there are ways to make the most of it! By choosing your destinations wisely and planning ahead, you can still enjoy the country’s magic without too much hassle. 

And let’s be honest, no matter how busy it gets, you’re still in freakin’ Thailand!!! It doesn’t get much better than that.

The Pros of Spending December in Thailand:

👍 Comfortable Weather: December brings mild temperatures and lower humidity, perfect for sightseeing, beach days, or trekking in the lush, green countryside.

👍 Dry Season: With less rain and more sunshine, it’s easier to plan your outdoor adventures. Hiking trails aren’t muddy and mosquitoes are less of a nuisance.

👍 Festive Atmosphere: While Christmas isn’t widely celebrated by locals, you’ll find festive decorations in popular areas and malls, giving you a touch of holiday spirit during your travels.

The Cons of Spending December in Thailand:

👎 Busy Season: The great weather draws in crowds, making December the busiest time of the year in Thailand. Expect popular tourist spots to be busy, and prices for accommodations and tours to be slightly higher.

👎 Advance Booking Needed: With so many visitors, it’s essential to book your hotels, tours, buses, trains, and even flights well in advance—sometimes weeks or even a month ahead for the most sought-after options. I once had to delay my visit to Chiang Mai because all the overnight trains were sold out!

👎 Higher Prices: Peak season often comes with increased prices for accommodations and services.

👎 Waterfalls Not at Their Peak: Some waterfalls may not be as full as they are during the rainy season.

👎 Monsoon Season: The islands in the Gulf of Thailand (Koh Samui, Koh Tao, and Koh Phangan) are rainiest this time of year. You may still get plenty of sun, but it’s a coin toss!

Weather and Temperature in Thailand in December

December is a fantastic time to visit Thailand, especially if you’re after cooler temperatures and less humidity. Don’t get confused by the word “cooler” here – Thailand is a tropical destination that is warm year-round, and there’s always a chance of rain!

For most of the country, December marks the start of the dry season, meaning fewer rainy days and plenty of sunshine. 

But with such a diverse landscape, the weather can vary depending on where you go—Northern Thailand, Central Thailand, and the islands all offer slightly different experiences this time of year.

Weather in Chiang Mai In December (Northern Thailand)

If you’re looking for a break from the heat, Northern Thailand is the place to be in December (and any time, really). 

Popular destinations like Chiang Mai, Chiang Rai, and Pai offer cooler weather, making them perfect for trekking, temple hopping, and enjoying the lush, green countryside.

In Chiang Mai, the daily highs hover around 84°F (29°C), with lows dropping to a pleasant 59°F (15°C) at night. It’s cool enough that you might want to pack a light jacket for the mornings and evenings, especially if you’re heading into higher elevations. 

I’ve spent Christmas in Pai, and while it’s not freezing by any means, the locals bundle up as if it were! If you love cooler(ish) weather, this region is a great escape in December.

Weather in Bangkok in December (Central Thailand)

In Bangkok and the central region, December offers a break from the city’s usual heat and humidity. 

Highs typically reach around 89°F (32°C), with lows dropping to a more comfortable 71°F (22°C). This makes it a great time to explore the city’s temples and markets without the oppressive heat you’d experience in the hotter months.

I love visiting Bangkok in December because it’s still warm enough to wear shorts, but you don’t feel like you’re melting every time you step outside. Just be prepared for a lot of people—Bangkok is one of the busiest spots in Thailand year-round, and December is no exception.

Weather in Phuket, Krabi, and Koh Samui in December (Southern Thailand)

December is when the southern part of Thailand truly shines – or at least most of it. 

Popular islands like Phuket, Krabi, and the Similan Islands are basking in their dry season, making it the perfect time for beach lounging, snorkeling, and diving. 

The average temperatures in Phuket in December range from 76°F to 89°F (24°C to 32°C), with clear skies and calm seas—ideal for water activities. Nearby islands like Koh Phi Phi are about the same.

If you’re heading to Koh Samui, Koh Tao, or Koh Phangan, be aware that these islands are still in their rainy season in early December. You’re likely to experience more rain and rough seas at the start of the month, but by Christmas, the weather usually starts to clear up. The chance of rain dramatically decreases as the month progresses, so if you’re traveling around the holidays, you should have mostly sunny skies.

I’ve spent New Year’s Eve on Koh Samui’s beaches, and even though it was still the tail end of the rainy season, I had a blast, and didn’t get much rain at all!

Best Places to Go in Thailand in December

Thailand in December offers travelers a wide range of experiences, from the chaotic capital and ancient ruins of the central region to the cooler northern mountains and the sun-drenched southern islands.

Let’s break down where to go in thailand in December, along with tips on what to expect in terms of weather and activities.

Central Thailand: Bangkok, Ayutthaya, and Kanchanaburi

Bangkok

Average December Temperature: 71°F – 89°F (22°C – 32°C)

December is one of the best times to visit Bangkok. The weather is warm but not overwhelmingly hot, making it perfect for sightseeing. 

You can spend your days exploring the Grand Palace, visiting temples like Wat Pho and Wat Arun, or shopping in vibrant markets. The cool evenings are great for rooftop bars or a stroll through the night markets. I LOVE this Bangkok food tour!

Just keep in mind, Bangkok is a tourist hotspot year-round —expect big crowds.

Ayutthaya

Average December Temperature: 69°F – 90°F (21°C – 32°C)

A short train ride from Bangkok, Ayutthaya is known for its ancient ruins and UNESCO World Heritage status. December’s mild weather makes it the perfect time to explore this historical city without breaking a sweat. 

You can easily spend a day or two cycling around the ruins, visiting temples, and learning about the old capital of Siam. If you don’t want to go on your own, this full-day tour is perfect.

Kanchanaburi

Average December Temperature: 67°F – 88°F (19°C – 31°C)

Kanchanaburi offers a mix of history and nature. Famous for the Bridge over the River Kwai and the Death Railway, it’s also home to stunning waterfalls and national parks. 

In December, the weather is perfect for hiking in Erawan National Park or relaxing by the river. It’s a great alternative if you want to escape the hustle and bustle of Bangkok for a few days.

Northern Thailand: Chiang Mai, Chiang Rai, and Pai

Chiang Mai

Average December Temperature: 59°F – 84°F (15°C – 29°C)

With cooler temperatures, Chiang Mai is an absolute favorite for December visitors (and my favorite place in Thailand for any time of year!). 

It’s the perfect time to explore the Old City, visit temples like Wat Phra That Doi Suthep, or venture into the mountains for hikes and waterfalls. 

Nearby Doi Inthanon National Park is famous for being the highest point in Thailand – and I was actually quite cold when I first got there (only in the early morning, then it warmed up!). The locals sometimes think frost is snow, and it’s adorable.

I’ve spent one December here, and while you might need a light jacket in the mornings and evenings, or when you’re riding a scooter, the days are perfect for exploring.

Don’t miss the Sunday Night Market!

Chiang Rai

Average December Temperature: 56°F – 81°F (13°C – 27°C)

Located further north, Chiang Rai is known for its stunning White Temple (Wat Rong Khun) and laid-back atmosphere. 

December is a wonderful time to visit since the weather is cooler, and you can comfortably explore the temples and surrounding countryside. It’s a quieter alternative to Chiang Mai, with plenty of charm and fewer tourists.

Pai

Average December Temperature: 57°F – 80°F (14°C – 27°C)

Located in the mountains, Pai is a popular spot for travelers looking to escape the busier cities. While it’s not exactly off-the-beaten-path, the three-hour drive from Chiang Mai, with its 762 hairpin turns, keeps it a bit less crowded.

I’ve celebrated Christmas in Pai, and it was a blast—everyone flocks to the cozy bars to celebrate! 

Surrounded by mountains and lush greenery, Pai is ideal for those who enjoy a laid-back vibe, acai bowls, hot springs, scooter adventures, and scenic hikes. December brings cool mornings and warm afternoons, making it perfect for exploring the countryside and taking in the mountain views.

Southern Thailand: Islands and Khao Sok National Park

Phuket

Average December Temperature: 76°F – 89°F (24°C – 32°C)

December is one of the best times to visit Phuket. The island is in its dry season, offering warm, sunny days and calm seas—ideal for beach lounging, snorkeling, and diving. 

While Phuket is honestly not my favorite destination in Thailand, it’s is a great base for exploring nearby islands like Phi Phi and Similan, or you can enjoy the lively nightlife in Patong. 

If you’re looking for something a bit quieter, consider Koh Lanta, a more laid-back alternative with beautiful beaches and fewer crowds.

⭐️My top pick for seeing beautiful Phi Phi Island without the crowds is this Phi Phi Sunrise Tour from Phuket, with a near-perfect 5-star rating.

Krabi

Average December Temperature: 71°F – 88°F (22°C – 31°C)

Like Phuket, Krabi enjoys sunny skies and calm seas in December, making it a fantastic spot for rock climbing, island-hopping, and exploring iconic beaches like Railay and Ao Nang. 

With towering limestone cliffs and crystal-clear waters, this region is perfect for adventure seekers or anyone looking for a beautiful tropical escape.

Similan Islands

Average December Temperature: 78°F – 84°F (26°C – 29°C)

For divers, December is prime time to visit the Similan Islands, one of Thailand’s top diving destinations. 

The water is calm, visibility is excellent, and the marine life is abundant.

After I got scuba certified in Koh Tao, I did a liveaboard scuba trip in the Similan Islands in December, and it was incredible! Too bad I didn’t see a whale shark – bad luck, since the boat saw one every trip before mine!

Khao Sok National Park

Average December Temperature: 71°F – 88°F (22°C – 31°C)

For something different in Southern Thailand, consider Khao Sok National Park. 

It’s one of the oldest rainforests in the world, and December’s cooler, drier weather makes it perfect for hiking, wildlife spotting, and exploring Cheow Lan Lake. 

Staying in a floating bungalow on the lake is one of my favorite experiences in Thailand—it’s serene, with breathtaking views of the limestone cliffs rising from the water.

Koh Samui, Koh Tao, and Koh Phangan

Average December Temperature: 73°F – 81°F (23°C – 27°C)

Caution: While most of Thailand enjoys excellent weather in December, Koh Samui, Koh Tao, and Koh Phangan are still experiencing the tail end of their rainy season. 

Early December often brings heavy rain and rough seas, which can disrupt beach plans or make ferries unsafe. 

However, the weather generally improves as the month goes on, so if you’re visiting toward the end of December, you might be in luck. Just keep in mind, you’re rolling the dice with these islands at this time of year. On the upside, there may be less tourists there!

Best Beaches in Thailand in December

Thailand is home to more incredible beaches than you could ever visit in a single trip, and each island has its own standouts. 

However, some of the most famous beaches can also be the most crowded, especially in December, so keep that in mind when planning.

Here are some of the best Thailand beaches to visit in December:

• Railay Beach (Krabi)
• Lamai Beach (Koh Samui)
• Maya Bay (Phi Phi Islands)
• Monkey Beach (Phi Phi Islands)
• Laem Tong Beach (Phi Phi Islands)
• Patong Beach (Phuket)
• Ao Nang Beach (Krabi)
• Kata Beach (Phuket)
• Karon Beach (Phuket)
• Haad Rin (Koh Phangan)
• Phra Nang Beach (Krabi)
• Hua Hin Beach (Mainland)
• Klong Dao Beach (Koh Lanta)
• Long Beach (Koh Lanta)

Best Things to Do in Thailand in December

If you’re planning a trip and wondering what to do in Thailand in December, let me tell you—this time of year is perfect for both adventure and relaxation. 

With the cooler weather, you can easily spend your days exploring temples, hiking, or diving into Thailand’s incredible food scene without worrying about the heat or rain. 

I’ve found December to be the best time to balance outdoor activities with cultural experiences, so whether you’re a beach bum, foodie, or thrill-seeker, you’ll find plenty to keep you busy.

Here are my top picks for things to add to your Thailand itinerary in December:

• Snorkeling/Scuba Diving
• Hiking
• Cooking Class
• Food Tour
• Temple Visits
• National Parks
• Night Markets
• Ziplining
• Yoga Retreats
• Traditional Thai Massage
• Boat Tours
• Muay Thai Fight
• Cabaret Show

👉 I use this travel insurance, which covers my medical coverage in the event of a motorbike accident, as long as I am appropriately licensed for the area I’m driving in (in Thailand, that’s an International Driver’s Permit validated for motorcycles) and am wearing proper safety gear such as a helmet. 

There are some exciting events happening too: 

• Christmas in Thailand: While Christmas isn’t widely celebrated in Thailand, you’ll find decorations in popular tourist spots and malls, especially in Bangkok. It’s not the same festive overload as back home, but it’ll still help you get into the holiday spirit! Some restaurants have Christmas dinners, too.

• King’s Birthday: Held annually on December 5, this national holiday celebrates the late king’s birthday and is also observed as Father’s Day. Expect closed government offices and decorated streets, especially around Bangkok.

• Phuket King’s Cup Regatta: From November 30 to December 7, 2024, Asia’s premier yacht racing event takes place in Phuket. If you’re a sailing enthusiast, this is an exciting time to be on the island!

Note: I see some other blogs mention the Loy Krathong festival, but that actually takes place in November, occasionally spilling into December. In 2024, the festival is on November 14-16 and in 2025 it’s even earlier in the month.

What to Wear in Thailand in December

When planning what to pack for Thailand in December, it’s all about staying comfortable in the heat while being prepared for occasional cooler mornings or evenings, especially if you’re heading north.

You’ll want to pack breathable, lightweight fabrics—think shorts, tanks, loose-fitting pants, and sundresses. Thai people often wear long sleeves for sun protection, so don’t be surprised if you see locals covered up, even in the heat.

• Breathable Fabrics: Think cotton, linen, or moisture-wicking fabrics for the hot days.

• Temple-Appropriate Outfit: Make sure to pack at least one outfit that covers your shoulders and knees for visiting temples. A light scarf or sarong can help cover up quickly if needed.

• Hat, Sunglasses, and Sunscreen: Essential for sun protection, especially when you’re out exploring or lounging on the beach.

• Light Sweater or Jacket: You’ll likely need this if you’re visiting northern Thailand or hitting higher elevations. I remember one December morning at Doi Inthanon National Park (the highest point in Thailand), where I was actually freezing at sunrise, only to be sweating a few hours later once the sun came up.

• Rain Jacket: December is generally dry, but if you’re headed to the Gulf islands like Koh Samui, where rainy season is still tapering off, a rain jacket can come in handy.

• Jacket for Scooter Rides: I always bring a jacket for nighttime scooter rides—the wind can get chilly, especially in the north, but otherwise, it’s rare you’ll need anything heavier than a light layer in Thailand.

Packing light but smart is key. Even though it’s winter, you’ll still be in a tropical climate, so dressing for warm weather is the way to go!

How Much Does December in Thailand Cost?

Since December is peak travel season in Thailand, you can expect hotel and flight prices to be higher than during other times of the year. While it’s still a relatively affordable destination compared to North America or Europe, prices do go up due to increased demand.

The good news? Whether you’re a backpacker, a luxury traveler, or somewhere in between (like me—a bougie backpacker), Thailand offers great value for money.

After flights, your biggest expenses will likely be accommodations, activities, and food.

I generally alternate between budget days (under $30 USD) and splurge days (closer to $60 USD) to balance things out.

Here’s a breakdown of what to expect cost-wise for a trip to Thailand in December:

• Accommodations: Thailand has options for every budget. If you’re on a tight budget, you can find nice hostels for under $15 USD per night. Private rooms in homestays or mid-range hotels usually cost around $30-$60 USD per night. If you’re after a luxury experience, the sky’s the limit—plenty of stunning resorts and boutique hotels are available, with prices ranging from $150 to $500+ USD per night.

• Food: Eating in Thailand is incredibly affordable, even in peak season. Local food, especially from street vendors or markets, is where you’ll save the most. A bowl of khao soi, for example, might cost you around $2 USD. International restaurants are a bit more expensive, but still reasonable compared to Western standards. I find alcohol in Thailand to be more expensive than other destinations, unless you stick to local beers.

• Flights: Round-trip flights to Thailand from North America or Europe can range from $600 to $1,700 USD in December, depending on how far in advance you book, how many stops, and whether you’re flying during the holiday rush. Keep an eye on flight comparison tools like Skyscanner for deals. Domestic flights within Thailand can range from $50 to $150 USD depending on the route, time of booking, and how many checked bags you have, so be prepared for slightly higher prices in December.

• Transportation: Long-distance buses and trains are also affected by the high season—prices might be slightly higher, and it’s crucial to book in advance. I’ve had trips where I had to switch up my itinerary because all the overnight trains were sold out!

• Tours and Activities: If you love to splurge on experiences like I do, this is where costs can add up. Scuba diving trips, cooking classes, and guided tours tend to be pricier but worth every penny.
