Thailand in December: Weather, Tips & More


Thailand’s beach resorts are bursting with travelers in December as visitors flock to experience Christmas in the tropics. A huge contrast to what you are likely to see back home, clear skies dominate the month in this part of the world, gifting day after day of uninterrupted sun. Beyond pleasant weather conditions, travel to Thailand in December means indulging in sightseeing tours. Be it the golden pagodas and gilt Buddhas of Bangkok that reflect sunlight in a charming display or the ruins of Ayutthaya that hark back to the heydays of the kingdom of Siam, no destination is out of bounds for anyone heading for the country during this time of year.

Although one of the coolest months of the year – which also makes it one of the best times to visit the country – temperatures still do not drop much below 30°C anywhere in-country during daytime in December. Taking it slow is therefore a very welcome ‘must’.

Temperatures are at their highest around Phuket, Bangkok, and Ayutthaya at 31°C, with Chiang Mai and the north two or three degrees cooler. Despite this, Phuket remains your best option for beach stays since Koh Samui can still receive some heavy downpours during this time. Water temperatures generally stay at 28°C and are ideal for swimming, water sports, and diving without needing a wetsuit.

For an insight into Thailand’s ancient past, be sure to make a stop to explore Ayutthaya, located an hour’s drive from Bangkok. The country’s capital in the 1300s, it is a treasure trove of fascinating temples, towers, and statues. When you travel to Bangkok you will see that it has a fair share of temples and palaces, often with glittering golden roofs. Phuket has a beach to suit everyone from nightclub lovers to nature aficionados, with plenty of opportunities to enjoy the warm seas too. Head north to Chiang Mai and you will be swapping beachside coconut palms for lush forests where elephants have roamed for centuries. This region is a walking country with trails meandering around its lush hills. However, if you are sticking to the south, Khao Yai National Park has both wild elephant herds and routes ideal for nice day walks, including one that takes you to a waterfall featured in the popular Hollywood movie ‘The Beach'. Finally, do not miss your chance to see the original Bridge on the River Kwai in Kanchanaburi. For information, read our article on how many days to spend in Thailand
