Cambodia is warm year-round, but the experience changes sharply between its dry and wet seasons. For most first-time visitors, November through February offers the easiest combination of lower rainfall and comparatively comfortable temperatures. Travelers who value greener landscapes, smaller crowds, and lower-season prices may prefer May through October, while March and April are usually the toughest months for heat.
Quick Answer
The best time to visit Cambodia for most travelers is November through February, when rainfall is lower and temperatures are more comfortable for Angkor and city sightseeing. March and April remain mostly dry but become very hot. May through October brings monsoon showers, greener scenery, fewer tourists, and rougher coastal conditions.
Key Takeaways
- November through February is the easiest period for Angkor Wat, Phnom Penh, and general sightseeing, but it is also part of Cambodia’s busiest tourism season.
- March and April are mainly dry but increasingly hot; Cambodia’s Ministry of Tourism identifies April as the hottest period of the year.
- May through October is the rainy or green season, with higher humidity, frequent showers, lush landscapes, and generally fewer tourists.
- Beach trips are most dependable in the dry season, when seas around the Cambodian coast and islands are usually calmer.
- Khmer New Year falls on April 14–16 in 2026, while the 2026 Water Festival runs November 23–25.
- Check current safety advice before traveling north or toward the Thailand border. Conditions and official travel advisories can change quickly.
Best Time to Visit Cambodia by Season
According to Cambodia’s Ministry of Tourism, the rainy season generally runs from May through October and the dry season from November through April. December and January are normally the coolest months, while April is the hottest.
| Period | What to Expect | Best For |
| November–February | Drier, comparatively cooler, peak tourism demand | First trips, Angkor, cities, beaches |
| March–April | Mostly dry but increasingly hot; April is typically hottest | Khmer New Year, travelers comfortable with heat |
| May–June | Rain increases, landscapes turn greener, tourist numbers ease | Value, photography, flexible sightseeing |
| July–September | Wet, humid, lush; heavier rain and rougher coastal seas | Lower crowds, green scenery, travelers who do not mind rain |
| October | Transitional; significant rain can continue while conditions gradually improve | Shoulder-season travel and greener Angkor scenery |
November to February: Best Overall Weather
November through February is the most straightforward period for a first visit. Rainfall is lower, humidity is generally easier to handle, and long days at archaeological sites are more comfortable than during the hottest months.
The tradeoff is popularity. The cooler dry-season period overlaps with Cambodia’s peak tourism season, particularly around Angkor and other major attractions. Hotels and popular tours can therefore be busier than they are during the monsoon months.
March and April: Dry but Very Hot
March remains suitable for sightseeing, but daytime heat becomes more demanding. April is normally the hottest time of the year, so temple visits are more comfortable early in the morning and later in the afternoon.
April also brings one of Cambodia’s biggest celebrations: Khmer New Year. Travelers visiting during the holiday gain a memorable cultural experience but should also expect local travel demand, festivities, business closures, and busy public spaces.
May to October: Green Season and Fewer Crowds
The southwest monsoon brings Cambodia most of its annual rain during this period. Rain often arrives in heavy bursts rather than falling continuously from morning to night, although prolonged rain does occur.
The rewards are greener rice fields, fuller waterways, dramatic skies, and fewer tourists at many major sights. Angkor can be especially atmospheric after rain, when vegetation and temple reflections become more vivid.
Note: Wet-season conditions are not equal everywhere. Cambodia’s Ministry of Tourism notes that the Cardamom Mountains receive particularly heavy rainfall and that coastal areas experience rougher seas and substantial rain. Allow extra travel time if your itinerary includes rural roads, trekking, ferries, or islands.
Festivals and Events in Cambodia
Khmer New Year: Family, Tradition, and Celebration
Khmer New Year, or Choul Chnam Thmey, is one of Cambodia’s most important annual celebrations. It takes place in mid-April and traditionally lasts three days. In 2026, the official public holidays are April 14, 15, and 16, according to the National Bank of Cambodia’s official holiday calendar.
Families gather, visit pagodas, honor elders and ancestors, share food, and take part in traditional games. Public celebrations can include music, performances, and water play, although activities vary by city and year.
April’s intense heat is the main weather drawback. Plan outdoor sightseeing early, drink water regularly, and allow more time for holiday traffic and crowds.
Water Festival: Boat Racing and the Tonle Sap’s Seasonal Cycle
The Water Festival, or Bon Om Touk, is held in November and is closely connected with the seasonal change in the Tonle Sap River system. Celebrations commonly feature boat racing, riverside gatherings, illuminated displays, entertainment, and ceremonies, although exact programs can vary.
In 2026, the official Water Festival holidays are November 23–25. The dates change from year to year, so travelers planning around the festival should confirm the calendar for their specific trip.
Festivals: A Window into Cambodian Culture and Community
Major festivals can be some of the most rewarding times to visit Cambodia because travelers see traditions that are less visible during an ordinary sightseeing day. They can also create higher domestic travel demand, road closures, crowded riverfront areas, and changes to business hours. Build some flexibility into your itinerary rather than treating a festival day like a normal touring day.
Tips for Traveling to Cambodia
Traveling to Cambodia can be an enriching experience, but preparation should reflect the season and the places you plan to visit.
- For dry-season trips: pack lightweight breathable clothing, sun protection, a hat, and a refillable water bottle.
- For wet-season trips: add a light rain jacket, quick-drying clothing, waterproof protection for electronics, and shoes that can handle wet or muddy paths.
- For temples: carry clothing that covers the shoulders and knees rather than relying only on beachwear or short sightseeing clothes.
- For mosquitoes: use an effective insect repellent and consider long sleeves or trousers when mosquitoes are active.
- For rural trips: allow extra transportation time during heavy rain and confirm road or boat conditions locally.
Before traveling, review the current CDC Cambodia Traveler View. CDC recommends that international travelers be up to date on routine vaccines, recommends hepatitis A vaccination for unvaccinated travelers, recommends typhoid vaccination for most travelers, and advises malaria-prevention medication for certain rural and forested areas. Cambodia is also an area where mosquito-borne diseases such as dengue occur.
Warning: As of July 2026, the U.S. State Department advises travelers to exercise increased caution in Cambodia and says not to travel within 50 km of the Cambodia–Thailand border because of armed conflict. Landmines and unexploded ordnance also remain a concern in some remote areas. Check the current Cambodia Travel Advisory shortly before departure because conditions can change.
The Best Time to Explore Angkor Wat
| Month | Typical Crowd Level | Weather Pattern |
|---|---|---|
| January | High | Dry and comparatively cool |
| April | High around Khmer New Year; variable otherwise | Very hot and mostly dry |
| July | Lower | Hot, humid, and wet |
| October | Low to moderate | Wet-season transition; rain still possible |
For weather comfort, November through February is an excellent time to explore Angkor. Lower rainfall and less oppressive heat make it easier to spend hours walking between temples. The downside is that these months are part of Cambodia’s busiest tourism period, so good weather does not mean empty temples.
Travelers who prioritize lower visitor numbers may prefer parts of the green season. Rain can complicate plans, but vegetation is lush and the temple landscape can look especially striking after a shower.
Sunrise remains one of the classic Angkor Wat experiences. Angkor Enterprise currently lists Angkor Wat’s opening hours as 5:00 AM to 5:30 PM, allowing entry for sunrise viewing.
Pro Tip: Sunrise itself can be crowded in peak season. After watching the sky brighten, consider moving away from the main reflection pools and exploring another section of the complex while large groups remain concentrated near the classic photo spots.
Angkor remains an active sacred landscape as well as an archaeological site. The APSARA National Authority asks visitors to wear appropriate clothing, respect monks and worshippers, avoid touching or climbing monuments, and take litter away.
The Monsoon Season in Cambodia
Cambodia’s monsoon season generally runs from May through October. Humidity increases and rain becomes more frequent, especially during the middle and later parts of the season. Heavy showers can temporarily flood streets, muddy rural roads, and delay outdoor plans.
That does not make the entire season unsuitable for travel. Rain often comes in concentrated bursts, and many days still include useful sightseeing windows. The countryside becomes intensely green, rice paddies fill, waterways expand, and popular archaeological sites commonly receive fewer tourists than during the cooler dry-season peak.
Travelers may also find more low-season accommodation deals, although savings vary by destination and property. The biggest practical drawback is transportation uncertainty. Ferries, island trips, trekking routes, and unpaved roads can be more vulnerable to poor conditions than city sightseeing.
Cambodia’s rainy season is not simply a “bad-weather season”: it trades predictable sunshine for greener scenery, lighter tourist traffic, and a greater need for flexible plans.
Cultural Etiquette and Customs in Cambodia
Respectful Greetings
A traditional Cambodian greeting known as the sampeah involves placing the palms together and making a slight bow. Visitors are not expected to master every level of formality, but a calm, respectful greeting and friendly demeanor are appreciated.
Dress Code and Modesty
Modest clothing matters most at temples and religious places. Cover your shoulders and knees and follow any posted requirements. Lightweight, loose-fitting clothing works well because Cambodia remains warm even during its cooler months.
Removing Shoes and Other Customs
Removing shoes before entering a Cambodian home is customary, and some religious or shrine areas may also require shoes to be removed. Follow your host or posted instructions.
Avoid touching another person’s head, pointing your feet at people or sacred objects, or using your feet to indicate something. Cambodia’s official traveler guidance also advises keeping public displays of affection respectful and notes special etiquette around Buddhist monks.
The Best Time to Visit the Beaches in Cambodia
The dry season from roughly November through April is the most dependable period for a Cambodian beach trip. Sunshine is more reliable and the sea is generally calmer, making swimming, snorkeling, diving, and boat transfers easier to plan.
Sihanoukville remains the main mainland gateway to Cambodia’s southern islands and has well-known beaches including Otres and Serendipity. Travelers seeking more of an island setting commonly continue to Koh Rong or Koh Rong Samloem.
Wet-season beach trips are possible, but they require more flexibility. Cambodia’s Ministry of Tourism notes that the coastline receives considerable rain and rough seas during the monsoon period. Boat schedules and water activities can therefore be affected by wind and storms.
Note: For island travel during the rainy season, check the local marine forecast and ferry status rather than relying only on a general Cambodia weather forecast.
Wildlife and Nature in Cambodia: When to Visit
Cambodia’s forests, wetlands, mountains, and seasonal floodplains make wildlife timing more complicated than simply choosing the dry or wet season.
For hiking in places such as the Cardamom Mountains or Preah Monivong Bokor National Park, the dry season usually offers easier trail and road conditions. Wet-season forests are greener and waterways fuller, but trails can become slippery, muddy, or difficult to reach.
Wildlife viewing does not follow one nationwide calendar. Rainfall, breeding cycles, water levels, and food availability affect different species in different ways. At Tonle Sap sites such as Prek Toal, for example, waterbird concentrations and breeding behavior are closely linked to the lake’s seasonal flood-and-recession cycle. Birders should therefore choose dates according to the specific species and sanctuary rather than assuming that the wet season is always best.
Local conservation guides can be valuable because they know current access conditions, recent sightings, breeding areas, and seasonal changes that cannot be predicted from Cambodia’s general weather calendar alone.
When planning what to bring, packing cubes can help separate light clothing from wet or muddy gear; the existing packing cube guide offers organization ideas. A reliable power bank can also be useful on long temple or rural travel days; see the existing international travel power bank guide. For compact toiletries, the existing travel toothbrush guide covers portable options.
