The single most useful thing you can tell a Songkran client is that the rules are set locally, change year to year, and are published late — often only weeks before the festival. Bangkok's 2026 edition made every official water-splashing zone alcohol-free and shut play at 22:00, which caught out plenty of agents who had sold the previous year's version of the same week. This guide from a Thailand DMC for travel agents covers the dates, the do's and don'ts that are actually enforced, what there is to do on the day, how a client physically reaches any of it once the roads close, and how to make sure they enjoy it.

The dates, and who actually sets them
Songkran's national dates are fixed: 13 to 15 April, every year. What is not fixed is everything else. The public holiday can be extended by Cabinet decision, and the water play in any given city runs to a locally-set window that may be shorter than the holiday, longer than it, or split across different zones on different days.
In Bangkok in 2026 the festival period ran 11 to 15 April, but water play on Khao San Road was permitted only from 13 to 15 April, between midday and 22:00. Chiang Mai traditionally runs longer and looser than the capital, and coastal towns run their own schedules again. So the honest answer to "which days will my client get soaked" is: it depends on the city, and it is confirmed closer to the time. Our 2027 calendar guide covers how the dates fall and what the bridge days do to flights.
The do's and don'ts that are actually enforced
These are not etiquette suggestions — they are the rules that had screening points and officers behind them in 2026, and a client who ignores them can be turned away at a zone entrance or fined.
- Don't bring a high-pressure water gun. Modified guns and improvised pressurised devices were prohibited outright, with entry screening to catch them. Ordinary water pistols are the norm.
- Don't bring powder or chalk. Talc and coloured chalk were banned in the official zones, and applying powder to someone without their consent is treated as a personal-rights violation rather than horseplay.
- Don't expect to drink in the official zones. Bangkok designated its water-splashing areas alcohol-free citywide in 2026 — a material change from earlier years.
- Do respect the closing time. Play in the official Bangkok zones ended at 22:00.
- Do use clean water. Guidance in official zones consistently specifies clean water only.
- Don't play from a moving vehicle, and don't ride in the back of a pick-up throwing water — road-safety enforcement is heaviest during this week of the year.
Brief this at booking, not at the airport. A client who has bought a pressurised water cannon in advance because they saw one in a video is a conversation you want to have in February.
The venues, and how they differ from each other
Bangkok designated 88 official alcohol-free water-splashing areas in 2026 — among them Lan Khon Mueang at City Hall, Silom Road, Khao San Road, Siam Square and CentralWorld. That designation matters commercially: an official zone has marshals, screening, medical cover and a defined closing time, and an unofficial street party has none of those.
They are also completely different products. Silom is a closed main road and the biggest, densest version. Khao San is the backpacker-famous one and the most intense per square metre. Siam Square and CentralWorld are mall-anchored, which means shade, toilets and a retreat indoors. Lan Khon Mueang, beside City Hall, sits closest to the ceremonial and cultural programme. Matching a client to the right one is most of the job — and the same logic applies in Chiang Mai, where the moat is one continuous event and position around it decides the day.
What there is to do besides getting wet
Plenty, and this is the part most briefs skip. Songkran is a New Year rite before it is a water fight: there are merit-making mornings at temples, the bathing of Buddha images, the pouring of scented water over the hands of elders, sand-pagoda building, parades and regional cultural programmes. Bangkok's flagship state festival runs a full cultural programme alongside the splashing, with performance stages, regional food and craft zones and dedicated quieter areas for families and older visitors.
This is the answer for the client who wants to experience Songkran without being in a crowd of thousands with a water gun — and there are more of those clients than agents expect. Send them to a temple in the morning and a cultural zone in the afternoon, and they will come home with the better trip.
How a client actually reaches any of it
Assume the car cannot get there. Main roads inside the festival zones close, traffic around them congeals, and a private transfer that works perfectly in March becomes useless on 13 April. The rail network is what works: Bangkok's official zones were chosen partly because BTS and MRT reach them, and the sensible plan is a transfer to a station outside the cordon and rail for the last leg.
Then plan the exit before the arrival. Leaving a zone at closing time alongside everyone else is the worst twenty minutes of the day, and a client briefed to leave forty minutes early — or to stay for a meal and go later — has a completely different experience. Build a meeting point that is a fixed landmark outside the crowd, agree a time, and expect phones to be wet and networks to be loaded. Our transport team plans these days around the closures rather than into them.
How to make sure they enjoy it
Waterproof the essentials and leave the rest at the hotel — phone in a sealed pouch, passport and cards locked away, a photocopy carried instead. Shoes with grip, because wet pavement plus crowd is the commonest injury of the week. Go in the morning if they want the ceremony and after lunch if they want the party; the two halves of Songkran genuinely are different festivals sharing a name.
And set the expectation honestly: everyone gets wet, including people who did not intend to. A client who has been told that finds it funny. A client who has not been told finds it an incident. That one sentence in the pre-departure brief does more for satisfaction scores than anything else on this list — see our first-time Songkran client guide for the fuller version of the personal brief.
What the ground partner carries on a festival file
The announcements, mostly. Zone lists, closing times, road closures and alcohol rules land locally, in Thai, weeks out — long after your client booked and often after your final documents went out. Somebody has to be reading them and re-planning the day quietly before the client notices. That is the everyday substance of Thailand DMC services for travel agents: licensed guides who know which zone suits which client, tours and activities re-timed around the closures, and a trade desk that answers on the day itself.
It is also where a Thailand DMC should tell you what is not yet knowable rather than guess. Nobody can confirm 2027's zone list in August 2026, and an operator who pretends otherwise is selling you a problem. See Bangkok for the city programme, and how we work with agents in your source market on festival-week files.
Frequently asked questions
What are the Songkran dates?
The national dates are 13 to 15 April every year, and the surrounding public holiday can be extended by Cabinet decision. The water-play window in any given city is set locally and can be shorter or longer than the holiday — in Bangkok in 2026 the festival period ran 11 to 15 April while Khao San Road water play was limited to 13 to 15 April, midday to 22:00.
Is alcohol allowed at Songkran?
In Bangkok in 2026 the designated water-splashing areas were declared alcohol-free citywide and play ended at 22:00. That was a change from previous years, and it is set annually by the city authorities rather than nationally, so it must be reconfirmed for the year your client travels rather than assumed.
What is banned in the official zones?
High-pressure and modified water guns, and talc or coloured chalk — with screening at zone entrances to enforce both. Applying powder to someone without consent is treated as a personal-rights violation. Guidance also specifies clean water only, and throwing water from moving vehicles is a road-safety matter that is policed hard during this week.
How does a client get to a water-play zone once the roads close?
By rail. Main roads inside the zones close and the surrounding traffic is unusable, so the workable plan is a transfer to a BTS or MRT station outside the cordon and the last leg on foot or by train. Plan the exit as carefully as the arrival — leaving at closing time with the whole crowd is the worst part of the day.
Is there a version of Songkran for a client who does not want a water fight?
Yes, and it is the older one. Merit-making at temples in the morning, bathing Buddha images, pouring scented water over elders' hands, sand pagodas, parades and cultural programme zones — the state festival in Bangkok runs these alongside the splashing, with quieter areas for families and older visitors. Many clients prefer it once they know it exists.
When will the rules for next Songkran be confirmed?
Late, typically in the weeks before April, and locally rather than nationally. That is the practical reason to place a festival-week file with a ground partner who is reading the announcements as they land. Send your dates and client profile to b2b@explera.co.th and we will flag anything that changes the plan as soon as it is published.
