When is S2O 2027?
The S2O 2027 dates are not yet announced. The festival normally runs over the Songkran weekend in mid-April: the 2026 edition ran from 11 to 13 April. We can book flexible hotel rooms around Songkran week now and fix the festival days once S2O confirms them.
Songkran week is one of the busiest weeks of the year for Bangkok hotels with a river or skyline view. If you want a suite and a driver for those days, ask us early, even before the line-up is out. We check the organiser's page each month and update this page when the dates appear.
What is S2O?
S2O is an electronic music festival held over Songkran, the Thai New Year. Water cannons soak the stage and the crowd all day. Big-name DJs play to a dancing crowd that is wet from the first set to the last. The 2026 edition was at S2O Land on Ratchada Road, near MRT Thailand Cultural Centre.
Your festival day starts in the afternoon, under the first spray. The best hour is after dark, when the headline sets begin. Wear light clothes that dry fast, dance for a few hours and leave before the final crowd rush. You stay wet the whole time, even in the VIP area.
What date is Songkran 2027?
Songkran 2027 falls on Tuesday 13 to Thursday 15 April, national public holidays in the Bank of Thailand's 2027 list. Songkran was added to UNESCO's list of the Intangible Cultural Heritage of Humanity in December 2023. Bangkok streets, hotels and flights are busy all week, so book early. See our Songkran guide.
Behind the parties, Songkran is a family festival. Thais visit temples, pour water over Buddha images and over the hands of older relatives, and return to their home provinces. Our pick is a morning at a temple before an afternoon at S2O, which shows you both sides of the holiday.
VIP tickets and the private way
S2O sells three ticket types, the festival says: Early Bird, General Admission in several tiers, and VIP. A VIP ticket gives you separate entrances, a VIP area and VIP restrooms. We print 2027 prices only when the organiser publishes them.
The private way adds what the ticket does not. A van with driver waits near the gate, so you can leave the moment you are cold or done. A hotel close to Ratchada keeps the ride short. Pack a waterproof pouch for your phone and passport. See our VIP van with driver.
Where to stay
Where you stay depends on the 2027 venue. If S2O returns to Ratchada, our pick is a suite in Sukhumvit or on the river with a car and driver. You rest by day, go to the festival, then change before dinner. Our where to stay in Bangkok guide compares the areas.
Rules and what to bring
S2O admits only guests aged 20 and over, in line with Thai law. Bring your original ID card or passport, because phone copies may be refused. DSLR and mirrorless cameras are not allowed. Vapes are illegal in Thailand. Bring a waterproof phone case, and leave dry clothes and shoes in the car for the ride home.
Other Songkran parties in Bangkok
S2O is not the only big party in Songkran week. The SIAM Songkran Music Festival runs from 10 to 13 April 2027 at Bravo BKK. On the Songkran holidays, the streets of Silom turn into one long water fight.
If your group wants more than one party, pair S2O with a rooftop night or a superclub table on the evening it ends. Our music festivals in Thailand page lists the full year, and the 2027 events calendar shows what else falls in April.
Plan it with Tanner
Example plan: two nights for S2O. On the first morning, a temple visit and the water blessing. In the afternoon, S2O with VIP tickets and a van with driver at the gate, from ฿6,500 for 10 hours, VAT included. Dry clothes wait in the car, then a late dinner and a rooftop table. Day two is for the pool and a massage.
Tell Tanner how many of you are coming and which days you want. One planner books the tickets, the hotel, a driver who waits and a table for the after-party, for two friends or a full company. Our Thai staff know the Songkran road closures. When the street party is not worth the soaking, we leave it out. We get back to you right away.
