Bangkok during Songkran: what actually happens April 13-15
Water fight on Silom Road during Songkran festival
Three days of city-wide water fights, 95°F heat and hotel rates that jump 40-70% — here is how the week really runs.
The three official days, and the two either side
Songkran is gazetted April 13, 14 and 15, but the water starts on the 12th in tourist zones and can drag into the 16th on Khao San. The government has, in most recent years, added a bridge day so the public holiday runs a full week — banks shut, ministries shut, and roughly half of Bangkok's white-collar workforce heads upcountry to their home provinces. The city empties of locals and fills with domestic tourists from the provinces and foreign visitors who booked six months out. Traffic on the 13th morning is the lightest you will ever see it.
The water fight is concentrated on three battlegrounds: Silom Road (closed to traffic, 500,000 people some years), Khao San and Soi Rambuttri, and RCA on Rama IX. Sukhumvit Soi 11 and the stretch outside Terminal 21 get a smaller but sustained soaking. Everywhere else — Chinatown, the Old City temples, Ari, the malls — carries on with ceremonial water pouring rather than pressure-washer combat. If you want to see Songkran without being in it, spend the days at Wat Pho or the Grand Palace in the morning and retreat to a hotel pool by 2pm.
What a room costs, and when the jump happens
Rates in Silom, Sukhumvit and Khao San climb from around April 10 and peak on the nights of the 12th, 13th and 14th. A four-star that runs $110 in early April sits at $170-190 across Songkran; a Khao San guesthouse room that is $22 in low season lists at $45-55 and sells out anyway. Riverside five-stars (Mandarin Oriental, Shangri-La, Peninsula) hold their rates better because their guests are not there for the water fight — expect a 20-30% bump rather than 70%. Book by January if you want a specific property; by March you take what is left.
The cheapest move is to stay outside the battle zones. Ari, Thonglor, Ekkamai and the Sathorn end of Silom see modest 15-25% rate rises and let you dip into the festival by BTS then escape. Riverside hotels in Thonburi (across from ICONSIAM) barely move on price and run shuttle boats. If you are on points, cash rates are so inflated that award nights represent unusual value — a hotel charging $220 for the night of the 13th may still cost the standard 30,000-40,000 points.
What is open and what is shut
Government offices, banks and most embassies close April 13-15 and often April 12 and 16 as well. Post offices shut. The Grand Palace and Wat Pho stay open with normal hours — they are actively part of the festival and get their biggest crowds of the year. Chatuchak Weekend Market runs if the dates fall on a weekend but with reduced vendors. The MRT and BTS operate as normal, though trains during Silom peak hours (2-6pm on the 13th and 14th) are packed and wet passengers are unpopular with the guards.
Restaurants split into two camps. Street food carts near battle zones close because the water ruins everything. Air-conditioned restaurants in malls (Terminal 21, EmQuartier, ICONSIAM, CentralWorld) run normal hours and are refuges. Fine dining stays open and is unusually easy to book — locals are away, and foreign visitors are on the street with a Super Soaker. Bars and clubs run late and hard; RCA and Route 66 have their biggest nights of the year. Convenience stores stay open 24 hours as always and sell out of dry bags and waterproof phone pouches by the 12th.
The heat, which is the real story
April is the hottest month in Bangkok, averaging 95°F daytime highs with humidity that keeps the felt temperature above 105°F from 11am to 4pm. The water fight exists because it is genuinely unbearable otherwise. This is not the tropical warmth of December — this is the kind of heat that gives unacclimatised visitors heatstroke by lunchtime if they walk the Old City temples without a hat and 3 litres of water. Hotels with pools earn their rate premium in April; hotels without them are a mistake.
Air quality is usually decent by April because the burning season upcountry has mostly finished and pre-monsoon winds have cleared the haze — PM2.5 typically sits at 25-40, versus the 80-150 of February and March. Rain is possible, in short violent afternoon storms that cool the city by 10°F for an hour then leave it steaming. Pack for heat, not for weather variety: one pair of shorts, quick-dry shirts, a rain shell that packs small, and shoes you do not mind being soaked because on the battle days everything is.
How to actually enjoy the water fight
Buy the gear on arrival, not at home. A Super Soaker at 7-Eleven costs $6-12; a waterproof phone pouch on a lanyard is $2-3; a dry bag for wallet and passport is $4-8. Wear a swimsuit or quick-dry shorts and a t-shirt you do not care about — white becomes transparent, so avoid it. Leave the passport in the hotel safe and carry a photocopy plus a $20 note and one card in the dry bag. Sunglasses are essential because the water often contains ice, powder and occasional soap.
Silom is the biggest scene but also the most exhausting — six hours of continuous soaking under 95°F sun. Khao San is smaller, more foreigner-heavy and more of a party. RCA is where young Thais go and has the best music. Pick one for a full day rather than trying all three. Go 2-6pm; before that it is quiet, after that it is drunk. Take breaks in the 7-Eleven for aircon and Gatorade. The city runs medical tents on Silom for heatstroke and cuts — use them without embarrassment.
The ceremonial side most visitors miss
Songkran is a Buddhist New Year, and the water fight grew out of a gentle ritual of pouring scented water over Buddha images and elders' hands. That ritual still happens, and it is the more interesting half of the festival if you can find it. Wat Pho, Wat Suthat and Wat Bowonniwet hold public water-pouring ceremonies where anyone can queue up, receive a small bowl of jasmine water, and pour it over a Buddha image for merit. Locals dress in flowered shirts (the modern Songkran uniform) and the atmosphere is reverent and photogenic.
Sand-castle building at temple grounds is the other lost tradition — bringing sand back to the temple you have carried out on your shoes all year, then decorating it with flags. Wat Saket (the Golden Mount) and Wat Arun do this well. The Bangkokians who stay in town rather than heading upcountry tend to do a morning temple visit on the 13th, a family lunch, then either the water fight or a quiet afternoon. If you want to photograph old Bangkok, the morning of the 13th at any major temple is the best day of the year.
The week after: the quietest Bangkok gets
April 16-22 is one of the best windows to visit Bangkok. The festival crowds have gone home, hotel rates drop back below early-April levels (often 10-15% under normal April rates as properties fill leftover inventory), and the city is genuinely empty because half the workforce is still upcountry. Restaurants that need reservations three weeks out take walk-ins. The Grand Palace queues are short. The heat is still brutal but you have the pools to yourself. It is a strange, holidayed-out version of the city that most visitors never see.
By the 25th normal service resumes and rates climb slightly again into the shoulder-season pattern that runs through May. If your dates are flexible and you want the Songkran story without the Songkran prices, arrive on the 15th (catch the tail of the water fight), stay through the 22nd, and you get the festival, the quiet week, and rates that average out at low-season levels. This is what returning visitors do.
Before you book
What people ask before booking Bangkok.
Yes — stay in Sathorn, Ari, Thonglor or riverside, avoid Silom and Khao San on the 13th-14th between 2pm and 6pm, and use the BTS/MRT to move around. Malls, fine-dining restaurants and temples outside the battle zones are dry. You will still get ceremonially sprinkled at temples, which is polite to accept.
Only if the water fight is the reason you came. Rates are 40-70% higher, the heat is the worst of the year, and half the city is shut. First-timers who want temples, food and shopping should pick November-February. Return visitors who want the festival should book by January.
White (turns transparent), leather (ruined), anything with a non-waterproof phone in the pocket, contact lenses without glasses backup, and any watch that is not water-rated. Bring flip-flops or sport sandals — closed shoes stay wet for two days in the humidity and blister your feet.
