Is December a good time to visit Thailand? Absolutely! It is one of the best months to visit Thailand, right in the heart of the dry season. Expect dry, sunny skies and comfortably warm temperatures across most of the country, except for the Gulf Coast, which stays wetter.
It's also the start of Thailand's peak season, with perfect weather, festive events, and travelers flying in from all over the world.
Below is our professional advice on what to expect from the weather, where to go based on your travel style, and how to plan around Christmas and New Year crowds.
What's the Weather Like in Thailand in December?
In December, Northern Thailand (Chiang Mai, Chiang Rai) and Central Thailand (Bangkok, Kanchanaburi) enjoy the most favorable weather for all activities. Expect average highs around 30°C (86°F) and only 0–1 rainy days. Just be ready for chilly nights in the mountains up north.
The south is a bit more variable. The west coast (Phuket, Krabi) is mostly dry, with the chance of light showers in early December (usually under 95 mm / 4 in). Seas are calm, water temperatures hover around 28°C (82°F), and all water activities are good to go.
The east coast (Koh Samui, Koh Phangan, Koh Tao) is still in the rainy season in December with occasional showers and rougher seas, improving towards the month's end.
Best Places to Visit for a First Thailand Trip in December
Go with the classic trio: Bangkok, Chiang Mai, and a beach destination on the Andaman Coast, like Phuket. These destinations offer a well-rounded taste of Thailand's culture, nature, and beach life, with vibrant festive decorations and events.
Bangkok: A Festive Urban Adventure
This bustling capital is a great place to arrive and ease into. First-timers won't miss the Grand Palace, thrilling tuk-tuk rides through Chinatown, and stunning sunsets at Wat Arun.
Christmas lights sparkle across malls like ICONSIAM and CentralWorld, and you'll find festive markets and rooftop countdown parties to ring in the New Year.

A peaceful contrast to Bangkok, Chiang Mai invites you to slow down. Join the century-old tradition of morning almsgiving, care for rescued elephants in an ethical sanctuary, and meditate to monk chanting at Wat Phra That Doi Suthep at sunset.
While Christmas here is quiet, the sky lantern release during the New Year countdown events is not to be missed for couples. It is equally magical but far less crowded than the famous Yi Peng Festival.

This is when the west coast of southern Thailand earns its postcard reputation—calm seas, no rain, vivid sunsets. Phuket, Krabi, and Khao Lak are popular choices.
In these islands, beach clubs and luxury resorts go all-out for Christmas and New Year's Eve, with festive dinners, decorations, and even fireworks. Looking for festive beach vibes? Phuket tops the list for both couples and families.
- Phuket is Thailand's most accessible and well-developed beach destination. If you're after a vibrant, activity-filled beach vacation, Phuket delivers. Couples can splurge on a beachfront pool villa or charter a private yacht to Phang Nga Bay, while families enjoy safe snorkeling, kayaking, or even diving together.
- Krabi offers a more scenic and laid-back vibe than Phuket. Beyond postcard-perfect sea views, it is best for adventure seekers. Kayak through mangroves, climb limestone cliffs at Railay, and hike to the Tiger Cave Temple.
- Khao Lak is the quietest and most nature-focused. It's the base for trips to the Similan and Surin Islands, with calm beaches, top-tier snorkeling and diving, and eco-experiences like waterfall treks and turtle sanctuaries.

While crowds are unavoidable in Bangkok, Chiang Mai, and Phuket during December, smart planning can help you enjoy the best parts without the hassle.
- Stay in quiet areas like the riverside in Bangkok and Chiang Mai or Kata Beach in Phuket.
- Book exclusive early-morning or late-afternoon tours to enjoy the major sights peacefully, away from the usual crowds.
- Consider adding less crowded alternatives to your itinerary (more below).

Quiet Getaways to Escape the Crowds
Want a more tranquil December escape? Head to Thailand's underrated gems that stay relatively quiet even in peak season.
- Kanchanaburi (2 hours' drive from Bangkok): It combines WWII history with natural charm. Ride the historic Death Railway, hike to waterfalls like Erawan, and sleep in a floating villa at The FloatHouse River Kwai.
Floating House River Kwai- Khao Sok National Park (Southern Thailand): Famous for jungle trekking, Khao Sok is one of Thailand's most underrated gems. For leisure travelers, stay in a floating bungalow, kayak through limestone cliffs, or take a nature tour.
Trekking in Khao Sok- Chiang Rai (northern Thailand): Cooler and less touristy than Chiang Mai, with incredible temples and hill country views. It is also home to some of Thailand's most luxurious jungle resorts, perfect for a private, intimate getaway.
Where to Avoid in December (or Go With Caution)
A few places may not offer the best conditions:
- Koh Samui, Koh Phangan, Koh Tao: These Gulf Coast islands still experience lingering rain in December. Sea conditions can be rough, and boat transfers may be disrupted. For beaches, we strongly suggest sticking to the Andaman Coast (Phuket, Krabi, Khao Lak).
- Popular islands like Phi Phi may be overcrowded, with services stretched thin around Christmas and New Year's. If you're eyeing these areas, aim for mid-December or earlier, or choose quieter nearby alternatives like Koh Lanta or Koh Yao Noi.
Is Thailand Expensive in December?
December is one of the priciest months to visit Thailand, especially from mid-December to early January.
International demand peaks during the Christmas and New Year holidays, driving up prices for flights, hotels, and tours, particularly in popular areas like Bangkok, Chiang Mai, and Phuket.
For example, a room at Pamookkoo Resort in Phuket costs about US$160 in early December, but spikes to US$270 during Christmas week. Domestic flights, ferries, and tours also book up quickly during this time.
However, compared to Western countries, Thailand remains a cost-effective holiday destination, especially for beach escapes. For your reference, a 10-day New Year tour costs only US$3,279 each (2 per room) in Thailand, with 4-star hotels, private tour, festival celebrations, and domestic flights.
Travel Tips: To make the most of your budget, travel before mid-December or choose quieter destinations like Kanchanaburi or Krabi for festive vibes without the crowds or high prices.
Book flights and key hotels at least 3 months in advance to secure the best availability and rates if you're visiting over Christmas or New Year's.
