December's weather in detail

Low humidity levels and average temperatures of 26°C in Bangkok and central Thailand are ideal for sightseeing. The north of the country also enjoys favourable weather conditions for trekking in the Golden Triangle region and cycling around the Chiang Mai countryside, with temperatures slightly cooler than in Bangkok (avg temp: 23-25°C). 

Sun seekers have the pick of virtually all Thailand’s beaches in December with daytime highs of 31°C not uncommon and blue skies the order of the day. The only region to see much rainfall is the south east (Koh Samui, Koh Tao, Khanom) although plenty of sunshine punctuates the showers. Dry conditions and warm sea temperatures off the west coast make December an ideal month for diving around Phuket, Khao Lak & Krabi.

Favourable weather conditions makes Thailand a great location for a Christmas holiday, especially the west coast beaches. Early booking is essential.
