What people love about Thailand Tours in December
- Thai Intro 12 Day
Amazing experience. Best bloke for it!!
- Thai Intro 9 Day
This tour greatly exceeded my expectations. I was hesitant about the authenticity of group travel, but this trip completely changed my perspective. I couldn't have asked for a better guide than Grant, he was so friendly and extremely accomodating. I thought we had the perfect amount of organised time and free time & my favourite part of the trip was Khao Sok. Will definitely recommend Intro Travel to friends.
- Best of Thailand - Feel Free Travel
Had such a great time with these guys. The north was amazing with the elephants, Bamboo rafting and hot springs. I was skeptical at first that 15 Days wasn’t enough but was perfect. A few of us stayed a little longer in Chiang Mai to do some ziplining. Excited to do the Sri Lanka trip now later in the year!

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.
