Why December to February, and what changes by month
In Bangkok, November to February is the cool, dry season and the most comfortable time of year. March to May is very hot, and June to October brings short, heavy afternoon downpours, so for a warm winter escape, December, January and February are a good three-month window.
Each month is a little different. December is the driest month of the year (12 mm on average) and also has the year's lowest daytime highs. January sits in between at 33°C by day and 23°C at night, and February is the warmest of the three at 34°C by day and 25°C at night. Bookings can fill up around year-end and Lunar New Year — check early.
December, January and February normals side by side
The figures below are 1991–2020 normals for the Bangkok Metropolis station from the Thai Meteorological Department submission · WMO normals collection (NOAA NCEI), rounded to whole numbers.
November to February is the dry season, and the normals agree: little rain in this period. For reference, the wettest month is September (336 mm on average). Temperatures are lowest in December and rise toward February, but with highs of 32–34°C and lows of 23–25°C, all three months are summer-clothes weather.
- December: high 32°C · low 23°C · rain 12 mm
- January: high 33°C · low 23°C · rain 24 mm
- February: high 34°C · low 25°C · rain 21 mm
What to wear: light clothes plus one temple outfit
With highs of 32–34°C and lows of 23–25°C, light, breathable short sleeves work by day, and you will not need a warm jacket at night.
Temples are the exception: cover shoulders and knees, and remove your shoes indoors. The Grand Palace and Wat Phra Kaew have a strict dress code, so wear long trousers and a top that covers your shoulders, and go early in the morning.
The midday heat is strong even in these months. The guide suggests alternating indoor and outdoor plans, going to Chatuchak Weekend Market in the morning with water, and bringing a hat and sunscreen to Ayutthaya, where shade is scarce. Do not drink tap water; buy bottled water.
- Light short-sleeved tops and trousers or skirts
- Long trousers and a shoulder-covering top for temples
- Hat and sunscreen
- Shoes that are easy to slip off
Year-end and Lunar New Year: what to know
Check official information for festival and event dates from December to February before you go. For year-end events or special opening times, check official information too. Songkran, the water festival, is in mid-April, so it falls outside this period.
Lunar New Year's Day (the 1st day of the 1st lunar month) falls on Sunday, 7 February 2027, according to the Korea Astronomy and Space Science Institute's lunar calendar data. For holiday dates, check the government's official announcement.
The day of the week matters too. Chatuchak Weekend Market opens on Saturdays and Sundays, so check whether your dates include a weekend before you plan.
A short 3–5 day plan: the guide's 4 days in brief
The guide suggests 3 to 5 days in Bangkok. The detailed day-by-day route is in our Bangkok 5-day itinerary, so here is just a short version of the guide's 4-day plan. Outdoor sights sit in the morning and around sunset, with a break in the middle of the day.
With 3 days, do days 1 to 3. With 5 days, give Chatuchak Market (weekend) and the Ayutthaya day trip (weekday) a day each. Wat Arun looks best at sunset, viewed from the opposite bank.
- Day 1: Grand Palace and Wat Phra Kaew in the morning → Wat Pho and a massage → ferry to Wat Arun, then Chinatown (Yaowarat) street food for dinner
- Day 2: Siam malls and Jim Thompson House → pool break in the afternoon → sunset at Mahanakhon SkyWalk
- Day 3: Chatuchak Market if it is a weekend, otherwise an Ayutthaya day trip → evening at a riverside or local night market
- Day 4: slow morning of cafes and massage in Sukhumvit → Airport Rail Link to BKK
Getting around and budget
In the city, combine the BTS Skytrain linking Sukhumvit, Siam and Silom (single tickets from machines, or top up a Rabbit card if riding often), the MRT Blue Line to Chinatown, Wat Pho (Sanam Chai station) and Chatuchak (tap in with a contactless credit card), and the Chao Phraya Express Boat for the Grand Palace and Wat Arun (Sathorn Pier connects to BTS Saphan Taksin). A ride-hailing app fixes the fare in advance, but rush-hour traffic is heavy; for a tuk-tuk, agree on the price before getting in.
From the airports, take the Airport Rail Link from Suvarnabhumi (BKK) (about 25-30 min, about 15-45 THB), or from Don Mueang (DMK) the SRT Red Line (about 15 min plus a transfer, about 20 THB; fare policy can change, so check official information) or the A1 Airport Bus (about 20-40 min, about 30 THB).
The guide's budget levels are about 1,200 THB (hostels, street food, public transport), about 3,500 THB (4-star hotel, restaurants and massages, a ride-hailing app) and about 10,000 THB+ (riverside luxury hotel, fine dining, rooftop bars). According to Thailand's Ministry of Tourism and Sports (2025), foreign visitors to Bangkok spent an average of 6,069.73 baht per person per day (spending there; excluding international airfare). Actual costs vary widely with your itinerary and lodging.
Checklist before you go
Street stalls and markets are cash-based, so carry small notes. Thai ATMs charge a fee per foreign-card withdrawal (check the amount at each bank), so withdraw larger amounts less often. Ignore anyone near the Grand Palace or famous temples who says it is closed today and offers a tuk-tuk tour; it is a classic scam.
- Check the December–February normals: 32–34°C by day, 23–25°C at night
- Long trousers and a shoulder-covering top for temples; hat and sunscreen
- Entry requirements: check official information
- SIM/eSIM: easy to buy at the airport, or set up an eSIM before you go
- Small baht notes
- VAT refund: 2,000 THB or more per store per day at shops showing VAT Refund for Tourists, claimed at departure; check the Thai Revenue Department's official information for details
- Tipping after a massage is not required, but about 50-100 THB is customary
