Bangkok in December — Full Picture
December is Bangkok's peak season — perfect weather (32°C / 88°F daytime, 21°C / 70°F nights, low humidity, no rain) combined with Christmas/New Year holidays drives maximum tourist demand.
Hotel prices spike 30-50% above mid-November. Book 6-8 weeks ahead. Mandarin Oriental, Anantara, Banyan Tree — all luxury properties hit annual rate maximums during Christmas-New Year week.
King Bhumibol's Birthday Memorial (December 5) is a major Thai public holiday. Many shops close. Sanam Luang in front of the Grand Palace hosts memorial events.
Christmas in Bangkok has its own character — major hotels (Mandarin Oriental, Lebua, Marriott) run Christmas Eve dinners ($150-300/person) and Christmas brunches. Iconsiam mall has the most spectacular Christmas tree and decoration display in Asia. Asiatique riverfront has illuminated installations.
New Year's Eve sees major countdowns at Iconsiam (Chao Phraya River fireworks), Asiatique (giant ferris wheel light show), CentralWorld in Siam (huge street party), and most sky bars (heavy minimum spend, ฿5,000-10,000 / $140-285 cover).
This is the month that defines Bangkok in Western imagination — clear blue skies, palm trees against the temples, golden hour at Wat Arun. Worth the premium prices once.
What to Wear & What to Pack
Light tropical clothing, ideally breathable cotton. Hat for sun protection. Light cardigan for over-air-conditioned malls and BTS.
