Bon Om Touk 2026: Cambodia’s Water Festival on November 23–25

The three official dates

The Royal Embassy of Cambodia in London lists November 23–25 as Water Festival public holidays in Cambodia for 2026. Its calendar distinguishes Cambodian holidays from UK holidays, so the country marker matters when reading the page.

A public-holiday calendar answers “which days are designated?” It does not answer “which races begin at which quay?” Keeping those questions separate helps prevent an old event timetable from being mistaken for current information.

Boats, spectators and the riverside setting

The National Museum of Cambodia describes the festival through boat races, illuminated boats and gatherings around Phnom Penh’s riverside. Those traditions explain why images of long racing boats and coordinated crews are closely associated with Bon Om Touk.

Racing boats and illuminated boats play different roles in the festival. Racing centres on crews working together on the river; illuminated boats create an evening spectacle. The cover photograph shows the latter, with lights tracing a boat’s outline against the night. Watching one does not mean you have seen the other.

This article does not publish a confirmed list of races, fireworks or concerts for 2026. The museum’s description provides cultural background rather than a promise that every element will take place at the same location this year.

What does the Tonle Sap reversal mean?

The festival is linked to the end of the rainy season and the changing flow of the Tonle Sap River. The river connects the lake with the Mekong system; its direction responds to seasonal water levels.

An FAO account of the Tonle Sap ecosystem explains the broad cycle. When the Mekong rises during the wet season, water can move toward the lake. As water levels later fall, the lake drains back toward the Mekong. The result is a landscape whose water and flooded areas change dramatically through the year.

Think of this as a seasonal process, not a switch operated by a festival date. The November holiday does not establish the exact hour or day when a river changes direction in a particular year. A calendar countdown can mark the start of the holiday period; it cannot measure the hydrological event.

How to verify a race or local celebration

Start with an announcement that explicitly names 2026. Check the issuing organisation, the city and the venue before assuming a programme applies to your trip. A Phnom Penh listing and a provincial race may have different arrangements even when both use the Water Festival name.

For a practical check, write down:

• The exact venue or riverside access point.
• The event date and start time, separate from the three-day holiday period.
• Whether entry, seating or transport requires a booking.
• The organiser’s most recent update and any changed access arrangements.

If any of those details are missing, treat the listing as incomplete rather than filling the gap from a photograph or an older year’s schedule. This is especially useful when comparing a tour seller’s description with an authority’s announcement.

Is this the same festival as Thailand’s Loy Krathong?

No. Both occur in a season when water and lunar calendars matter to regional observances, but their names and traditions should remain distinct. Cambodia’s Water Festival is strongly associated with racing boats. Loy Krathong is known for decorated floats placed on water.

A shared month does not make one event a substitute name for the other. Nor should an image of Thai floating baskets be used to illustrate a Cambodian boat race without explaining the different context.

For a broader view of the dates, use the November calendar. For the race you actually intend to watch, rely on its own current programme.
