Songkran, the Thai water festival, is one of three major New Year celebrations held across mainland Southeast Asia each April. Visitors can expect three-day observances in Cambodia (Chaul Chnam Thmey), Laos (Boun Pi Mai) and Thailand, each shaped by Buddhist practices and special local customs.
What Songkran, Chaul Chnam Thmey and Boun Pi Mai are
These three events mark the traditional New Year in Thailand, Cambodia and Laos respectively and are observed around mid-April. Although the calendar date aligns across the region, each country has developed a distinct set of rituals and names for the period: Chaul Chnam Thmey in Cambodia, Boun Pi Mai in Laos and Songkran in Thailand.
All three festivals combine religious duties — such as visiting temples and making merit — with communal acts intended to symbolically clear away the old year’s misfortune. Water plays a central role across the region, used in cleansing ceremonies and, increasingly, in large-scale public splashing that draws both locals and travellers.
Key features and highlights
Cambodia’s Chaul Chnam Thmey runs for three principal days commonly known as Maha Sangkran, Virak Vanabat and Vearak Loeng Sak. The sequence begins with formal prayers and temple visits, moves into generous offerings and acts of charity, and finishes with ritual washing of Buddha images and elders using perfumed water.
In Laos, Boun Pi Mai usually spreads over three days as well, sometimes longer in certain towns. The days are often referred to as Sangkhan Luang (preparatory cleaning), Sangkhan Nao (a transitional ‘no day’), and Sangkhan Kheun Pi Mai (the opening day of the new year). Building small sand stupas at temples, offering alms to monks and gentle water-splashing are common activities.
Songkran in Thailand retains the temple rites but has become widely known for its large-scale water celebrations. What began as ritual cleansing now frequently takes the form of organised water fights in urban areas and on popular tourist routes; local markets and city streets become focal points for mass participation.
- Religious ceremonies: temple visits, alms, merit-making.
- Ritual cleansing: water used on Buddha images and elders.
- Public celebrations: splashing water, parades and small shrines.
- Unique local features: sand stupas in Laos, formal charity days in Cambodia, large-scale street water play in Thailand.
Practical tips for travellers
Travel during mid-April is busy and hot across the region. Phnom Penh and many other inland cities typically experience high temperatures and rising humidity during this period; those planning a city visit should check local forecasts and plan outdoor activities for cooler parts of the day. For more detailed climate guidance, consider reading a dedicated overview of Phnom Penh weather in April.
When joining street water activities, protect electronics with waterproof cases and wear clothing suited to getting wet. If you prefer quieter moments, visit temples early in the morning when religious observances are most noticeable and crowds are smaller. For cross-border travel during festival season — such as trips along the Mekong between Laos and Cambodia — check boat and cruise options in advance because schedules can change around holidays; a useful reference is the Mekong River cruise guide.
- Carry cash: many small vendors and temple donations are cash-only.
- Water etiquette: in religious settings, be respectful — splashing is usually for streets, not inside shrines.
- Health: stay hydrated, use sun protection and avoid extended exposure during midday heat.
- Transport: book major connections and accommodation early, as demand rises sharply.
Cultural context and meanings
All three festivals reflect Buddhist notions of purification, merit and respect for elders. The act of pouring scented water over Buddha images or family elders is symbolic rather than merely celebratory; it represents a wish for renewal and good fortune in the coming year. In Cambodia, the sequence of Maha Sangkran, Virak Vanabat and Vearak Loeng Sak carries specific communal and spiritual purposes tied to gratitude, charity and purification.
Laos places notable emphasis on community rituals such as building sand stupas at temple grounds and participating in early-morning alms-giving. Although popular culture aspects — notably water-splashing — are visible across the region, the ceremonies retain a primarily religious character for many local participants. Travellers report that observing a morning temple ceremony offers clear insight into the festival’s traditional significance.
- Symbolic cleansing: water and perfumed washes are meant to remove misfortune.
- Merit-making: offering alms, donating to monks and temple upkeep.
- Family and respect: many households perform specific rites to honour elders and ancestors.
Who these festivals suit
These April festivals appeal to a wide range of travellers. Those interested in religious culture and traditional rituals will find meaningful ceremonies at temples across Cambodia, Laos and Thailand. Visitors who enjoy lively street events and high-energy communal activities will be drawn to Thailand’s large-scale water celebrations.
Families travelling with children can usually enjoy safe, playful splashing in designated areas, though supervision is important because crowds can be dense. Photographers and cultural observers often recommend attending early-morning temple services to capture quieter, more reflective moments before the public festivities swell.

Comparisons and alternatives
While all three festivals share a seasonal time window and similar religious roots, their public character differs. Cambodia emphasizes formal rites and charity; Laos blends quiet temple customs with family-oriented sand-stupa building; Thailand has turned much of the celebration into widespread public revelry with a party-like atmosphere in many urban centres.
If you prefer smaller crowds, consider attending events in provincial towns or scheduling temple visits during weekdays rather than weekends. Alternatively, travellers seeking a relaxed riverine pace can time a Mekong cruise outside peak celebration zones to experience regional culture more slowly.

Yes. Early mornings are often the best time to observe temple rituals when worshippers gather for merit-making and alms. Dress respectfully: cover shoulders and knees, and remove hats inside shrines.
How does weather affect festival plans?
April is hot in much of mainland Southeast Asia, which makes water-based activities popular. High temperatures can affect transport and outdoor plans, so check local forecasts and plan accordingly.
