July sits deep in Cambodia’s rainy season, and unlike the packed calendars of April or May, the country has no official public holidays this month at all. What it does have is a quieter, more contemplative marker: the start of Buddhist Lent, when monks across the country retreat into their pagodas for three months of study and meditation.
This guide lists the most important Cambodia events in July 2027, including confirmed dates, locations and practical information for travelers.
Cambodia Events in July 2027 at a Glance
| Date | Event | Location | Type | Tourist Relevance |
|---|---|---|---|---|
| Around July 19â20 (estimated) | Choul Vossa (Beginning of Buddhist Lent) | Pagodas nationwide | Religious Observance | Low-Medium |
Around July 19â20 (Estimated): Choul Vossa (Beginning of Buddhist Lent)
When: Timed to the first day of the waning moon following the full moon of the 8th lunar month; multiple lunar-calendar estimates for 2027 cluster around July 19â20. This is not an official Cambodian public holiday, so no government date is gazetted for it
Where: Buddhist pagodas nationwide
Type: Religious observance (not a public holiday)
Choul Vossa marks the day monks formally enter Vassa, the three-month Rains Retreat, and commit to remaining within their pagoda grounds until it ends in October. The tradition dates back to the time of the Buddha, who asked monks to avoid traveling during the rainy season so as not to damage crops or harm small creatures underfoot.
During Vassa, monks deepen their meditation practice and study of Buddhist scripture, while lay Cambodians visit pagodas to bring pre-dawn offerings of food and incense and receive blessings in return. It is a cornerstone of Khmer Buddhist life, observed continuously for centuries, but it unfolds quietly rather than as a public spectacle.
For travelers, it is not a day of closures or crowds â it is simply a good time to visit a local pagoda respectfully and observe everyday religious life away from the main tourist circuit, particularly in and around Siem Reap where temple culture runs deepest.
Tourist tip: If you visit a pagoda during this period, dress modestly, keep your voice low, and avoid entering areas set aside for monks unless invited.
What Is July Like for Travelers in Cambodia?
July is squarely in Cambodia’s rainy season, with regular afternoon and evening downpours, high humidity, and the countryside at its greenest and most photogenic.
It is also one of the best months to see the Tonle Sap Lake at its most dramatic, as monsoon rain and Mekong floodwater swell it to several times its dry-season size. Tourist numbers remain low, hotel rates stay favorable, and Angkor Wat and other major sites are noticeably less crowded than during the DecemberâApril peak.

Where to Stay in Cambodia in July
With no major festivals to plan around, base your stay on the sights you want to prioritize rather than any specific date.
Siem Reap
Siem Reap remains the essential base for Angkor Wat, and July’s low season brings some of the best hotel value of the year alongside noticeably thinner temple crowds.

Phnom Penh
Phnom Penh works well in July for travelers focused on museums, markets and riverside dining, all of which sit comfortably between rain showers.

July Events in Cambodia: What Should Tourists Prioritize?
July has no public holidays and only one notable date on the calendar, so this is a month better planned around weather and value than around events.
- Choul Vossa â around July 19â20, worth knowing about if you have an interest in Buddhist religious life and want to visit a pagoda respectfully during this period
- Tonle Sap at flood season, not tied to a specific date but one of the best reasons to visit Cambodia in July for scenery and boat trips
Bottom Line
July is one of Cambodia’s quietest months on the events calendar, with no public holidays and only the low-key beginning of Buddhist Lent to mark on your itinerary.
What it lacks in festivals it makes up for in value and scenery â thin crowds, discounted rooms, and a swollen, dramatic Tonle Sap Lake worth building a day trip around.
If you are planning a July trip, use this calendar as a starting point and check the latest weather forecasts before traveling, since rainy-season downpours can affect road conditions in rural areas.
