What people love about Thailand Tours in December
- Thai Experience
What an amazing trip! From the minute you get of the plane to when you leave you know you are being looked after and have the Alan and Jay who will do anything to make the trip great for you! If you are worried about being a Solo traveller you will be well looked after and suitable for couples or groups. Would book again with Intro :)
- Thai Intro 9 Day
Thaintro was a great choice for me coming to Thailand alone. Thailand is very backpacker friendly I think, but there's always the little things that will catch you out, and that your Lonely Planet etc just doesn't cover. Having a tour leader to answer any Q's and having knowledge only the locals would know (as well as providing chauffeur service from airport to guest house) is great. The trip never felt too regimented in any way like many tour groups, and also without the teacher-like tour lead. There was a great balance of cultural stuff and fun (maybe slightly more balanced towards the fun) ;) I met a great bunch of people and the week was a definite highlight of my travels, just didn't last long enough! If your in 2 minds I'd say go for it, really don't think you'll regret it. Think I've rambled enough. Enjoy your trip, very jealous :-)
- Thai Intro 12 Day
I had the best week of my life. met wonderful people and had a wonderful time. everything went perfekt thanks to Alan and Adam
What our customers ask about Thailand Tours in December 2025
What is the weather like in Thailand during December?
December brings ideal weather conditions to Thailand with temperatures ranging between 75-85°F (24-29°C) in Bangkok and the north. The northern city of Chiang Mai stays cooler with temperatures from 60-75°F (15-24°C). Southern beach destinations like Koh Phangan remain warm at 80-85°F (27-29°C). The pleasant climate creates good conditions for outdoor activities and temple visits. A TourRadar traveler mentioned "The weather in December was perfect for exploring temples and doing outdoor activities."
Are there any special festivals or events in Thailand during December?
The month starts with the King's Birthday on December 5th bringing nationwide celebrations and ceremonies. Tourist areas come alive with Christmas and New Year festivities. Chiang Mai's streets fill with night markets and traditional lantern displays. At places like the Kata Beach Resort in Phuket special holiday dinners need advance reservations. The combination of local and international celebrations makes December a lively time across the country.
What kind of accommodations are available in Thailand during December?
Since December marks the peak tourist season early booking is essential. Places range from high-end options like Na Nirand Romantic Boutique Resort in Chiang Mai to mid-range choices such as True Siam Rangnam in Bangkok. Beach destinations offer oceanfront properties including the Oceanfront Beach Resort in Phuket. As one traveler noted: "The Movenpick Hotel Bangkok and Kata Sea Breeze Resort Phuket were excellent choices for our December stay providing perfect locations for both city exploration and beach relaxation."
What are the best places to visit in Thailand during December?
The cooler weather makes this an excellent time to explore Bangkok's temples including Wat Pho and Wat Arun. Nature lovers head to the floating bungalows at Khao Sok National Park while beach enthusiasts flock to Koh Phangan and Phi Phi Islands for water activities. A TourRadar traveler shared: "Staying at the Sarana Bungalows in Koh Phangan in December was magical - perfect beach weather and the clearest waters for swimming." The mild temperatures in Chiang Mai create good conditions for temple visits and wildlife encounters.
How crowded are tourist destinations in Thailand during December?
December sees peak visitor numbers especially during the holiday season. Major attractions like Bangkok's Grand Palace Phi Phi Islands and Phuket's beaches get particularly busy. According to a G Adventures traveler: "Book accommodations well in advance especially on islands like Koh Phangan and Koh Tao. The Full Moon Party on Koh Phangan draws massive crowds if it falls in December."
Is December a good time for island hopping in Thailand?
The month offers excellent conditions for exploring Thailand's islands. The Andaman Sea along the west coast including Phuket and Phi Phi shows calm waters and good visibility. A G Adventures sailing participant noted: "The December sailing conditions were perfect with calm seas and clear visibility for snorkeling around islands like Ko Phi Phi and Ko Lanta."
