Best Time to Visit Cambodia 2026: Angkor Wat, Siem Reap, Phnom Penh & Koh Rong

Best Time to Visit Cambodia 2026: Complete Seasonal Guide

Cambodia has a tropical monsoon climate with two distinct seasons — the dry season (November–April) and the wet season (May–October). Unlike some Southeast Asian destinations, the wet season in Cambodia is not terrible for travel — the Angkor temples are surrounded by monsoon-fed moats and jungle, and the green season has its own beauty.

Dry Season vs. Wet Season

Dry Season (November–April): The Classic Visit Window

November–February: The finest time — temperatures 25–35°C; low humidity; full sun; the busiest period for Angkor tourism.

March–April: Hot (35–40°C); dust; the last of the dry season. The water levels in Angkor’s moats drop, revealing the stone foundations. Khmer New Year (mid-April 2026): The most significant Cambodian festival — celebrated with water festivals, rice ball ceremonies, and the most vibrant atmosphere in Siem Reap.

Wet Season (May–October)

May–September: The monsoon season — the Tonlé Sap lake (the largest freshwater lake in Southeast Asia) reverses its flow as the Mekong flood pushes water back through the Tonlé Sap River. The lake expands from 2,500 km² to 16,000 km² — the flooding mechanism that made the Khmer civilization agriculturally possible.

Advantages of wet season: Fewer tourists (15–30% fewer at Angkor); dramatic cloud formations behind the temples; the moats full; the jungle surrounding the temples at its most lush; lower hotel prices.

The light on wet season afternoon storms: The most dramatic photography at Angkor occurs when afternoon clouds build — the dark sky behind the sandstone towers is the most cinematic Angkor image.

October–November: The end of the wet season — the lake water retreats, flooding the surrounding floodplain; boat trips across the Tonlé Sap in October are extraordinary.

Angkor Wat: The Essential Guide

The complex: The Angkor Archaeological Park (401 km²) contains the ruins of several capitals of the Khmer Empire (9th–15th century), including Angkor Wat (the largest religious monument in the world by area, 402 acres) and Angkor Thom (the last great capital).

Angkor Wat Itself

What it is: Built by Suryavarman II (1113–1150 AD) as a state temple dedicated to Vishnu — the largest temple in the world, also one of the most perfectly proportioned. The outer gallery is decorated with the longest continuous bas-relief in the world (800m, carved with scenes from the Mahabharata and the Ramayana, the creation myth of the Churning of the Ocean of Milk, and Suryavarman II’s army in procession).

The sunrise: Angkor Wat faces west (unique among Khmer temples — most face east) — the sunrise over the reflection pools fills the western facade with backlit gold light. The crowd at the main reflecting pool at sunrise is approximately 1,500–2,000 people in peak season; the northern reflecting pool has the same view with 80% fewer people.

Best entry time: 5am (gates open at 5am; the sunrise is around 5:45–6:15am depending on the month).

Angkor Thom and the Bayon

Angkor Thom (the great city, 9km² enclosed by a 8m wall and a 100m-wide moat): The final capital of the Khmer empire, built by Jayavarman VII (1181–1218).

The Bayon (the state temple of Angkor Thom): 54 towers, each carved with the famous face of Jayavarman VII — the “Face Towers” (216 enigmatic faces in total; the expression is the most frequently reproduced image in Khmer art). At sunrise, the light on the faces is extraordinary.

The Elephant Terrace: 350m-long terrace decorated with elephants and Garuda; used as a viewing platform for royal ceremonies.

Ta Prohm (the “Tomb Raider Temple”)

The most atmospheric temple in Angkor — the jungle has been allowed to grow over the stone structures; Tetrameles nudiflora trees (the “strangler figs”) send roots over and through the walls, creating the specific aesthetic of Angkor as it appeared to French explorers in the 19th century (and to audiences of the 2001 Angelina Jolie film).

Best visit time: Early morning (before 8am) or late afternoon (after 4pm); the midday sun is harsh and the crowds are at their maximum.

Banteay Srei

The finest carving in Angkor — 37km northeast of Siem Reap; the “Citadel of Women” (so named because the carvings are too delicate to have been made by men, according to traditional Khmer belief). The pink sandstone and the density of the decorative carving (every surface covered; no plain stone visible) make Banteay Srei the most aesthetically compelling temple in the complex despite its smaller size.

Phnom Penh

When to Visit

Best: November–February (dry season); the city is manageable year-round.

What to See

Tuol Sleng Genocide Museum (S-21, the former high school used by the Khmer Rouge as an interrogation center, 1975–1979): Of the approximately 17,000 people imprisoned at S-21, only 12–17 survived to see liberation. The school has been preserved as a museum — the classrooms converted to torture chambers, the documentation (photographs of every prisoner taken on arrival) displayed. One of the most significant historical sites in Southeast Asia.

The Killing Fields of Choeung Ek (15km south of the city): Where many S-21 prisoners were executed. The memorial stupa contains the exhumed skulls and bones of victims. The audio guide (narrated by survivors) is among the most powerful museum audio experiences in the world.

The Royal Palace and Silver Pagoda (Samdach Sothearos Blvd): The Khmer royal palace complex (1866, rebuilt 1913) with the Silver Pagoda (floor covered in 5,329 silver tiles weighing 125g each, total 660kg of silver) and the Baccarat crystal Buddha.

The Central Market (Phsar Thmei): The Art Deco market building (1937) is the finest surviving Art Deco market in Asia — the yellow concrete dome is Phnom Penh’s most distinctive structure.

Accommodation Near Angkor

Amansara (the finest resort in Cambodia, converted from a Sihanouk-era villa): The standard 6-7 room suites have private pools; the tour program uses vintage Mercedes tuk-tuks for early morning temple access before the public. Rate: ~$1,000+/night
Phum Baitang (Vithei Charles de Gaulle): 45 wooden villas in a traditional Khmer village setting; the best pool architecture near Angkor
Shinta Mani Wild (remote, Cardamom Mountains): For combining Angkor with Cambodia’s wilderness; the zip-line over the river is one of the finest hotel experiences in Southeast Asia

FAQ

How many days for Angkor? Minimum 2 days (Angkor Wat, Bayon, Ta Prohm); 3–4 days for the complete complex (adding Banteay Srei, Preah Khan, the Roluos Group, Beng Mealea). A week allows genuine exploration of the less-visited areas.

Is Cambodia safe? Yes — Cambodia is safe for tourists. The main precaution is land mines (still present in rural northwestern areas near the Thai border; don’t walk off marked paths outside tourist areas). Petty theft and bag-snatching on motorcycles occur in Phnom Penh.

When is Angkor least crowded? May–September (wet season): 15–30% fewer visitors. Weekdays always quieter than weekends (Chinese and Thai tour groups come from Bangkok). The extreme heat of 11am–3pm reduces crowds at any time of year — most serious visitors are at the temples by 5:30am and finished by 11am.
