Best Time to Visit Cambodia: Angkor, Heat & Month-by-Month Guide

Cambodia sits between November and March in something close to dream condition. Angkor Wat in the morning mist, Khmer temples in gentle light, temperatures around 28 to 32 degrees without the crushing humidity of wet season. No wonder most tourists make for Cambodia in those months. But the other months have their own appeal too, and travelers who plan cleverly discover a Cambodia without the crowds.

Cambodia runs on a classic monsoon climate: dry season from November to April, rainy season from May to October. Heat stays high year-round. Anyone experienced with Southeast Asian travel knows this is manageable when you adjust your rhythms. The question is not whether it will rain, it’s which conditions best suit your particular travel style.

When Is the Best Time to Visit Angkor Wat?

Angkor Wat and the surrounding temples near Siem Reap work year-round. But the standard answer is November through March. In this window the sky runs clear, temperatures stay manageable, and evening light on the temples is breathtaking. Sunrise over Angkor Wat around 5:30am, with the main temple reflected in the pond out front: this is the moment many travelers come for.

The catch: everyone else knows this too. December and January are peak crowd periods. Busloads of tourists in a confined space can noticeably flatten the experience. Travelers who want the Angkor sunrise nearly to themselves should book early and aim for less-visited satellite temples like Pre Rup or Ta Prohm immediately after opening at 6am.

April is technically still dry season, but temperatures in Siem Reap hit 35 to 40 degrees, making temple visits between 10am and 4pm genuinely exhausting. Prices have already dropped by April and tourist numbers are low. Early mornings and evenings work beautifully.

During rainy season (May to October) tourist numbers drop sharply. The temples feel less accessible but often more atmospheric. Green growth overtakes stone walls, the jungle breathes. Ta Prohm, the temple threaded through by tree roots, is especially dramatic in the wet season.

What’s the Best Time for Cambodia’s Coast?

Cambodia’s coastal towns of Sihanoukville, Kep, and islands like Koh Rong and Koh Rong Samloem operate on almost opposite logic from Angkor. November to April is good here too, but the best conditions for beaches and snorkeling often come during the transition: October and November bring freshly cooled temperatures, clear water, and very few visitors.

During rainy season (May to September) some coastal islands become difficult to reach by day boat. Koh Rong runs much quieter, and prices drop. Backpackers who want the island almost to themselves come during this shoulder period.

For combination trips with the neighboring country, the Vietnam 2-week route is worth checking, as many travelers link both countries in a single trip.

According to Cambodia Tourism, Cambodia receives around 6 million visitors annually, with about 40% arriving in just the three months of December through February.

How Hot Does Cambodia Actually Get and What Does That Mean for Travel?

Cambodia is among the hottest countries in Southeast Asia. In Siem Reap and Phnom Penh, the thermometer regularly hits 38 to 42 degrees in the afternoon from March to May. That is extreme heat. First-time visitors to the region tend to underestimate it.

Practical implications: plan temple visits for early mornings (6 to 9am) and late afternoon (4 to 6pm). Use midday for restaurants or air-conditioned cafes. Light, loose clothing, strong sunscreen, and constant hydration are necessities, not suggestions.

Rainy season paradoxically often brings slight relief. The showers that typically fall between 2pm and 5pm cool the air to a more manageable 28 to 30 degrees. Travelers who struggle with heat sometimes prefer the rainy season precisely because daily life feels more bearable.

Month-by-Month: When Should You Go to Cambodia?

November: Dry season begins, temperatures drop to a comfortable 28 to 32 degrees, rivers still full from monsoon. One of the best months. Prices still moderate.

December/January: Peak season, best conditions, highest prices and tourist crowds in Siem Reap. Book months ahead.

February/March: Excellent weather, slightly easing tourist flow. March gets hot.

April: Khmer New Year water festival, extreme heat, lower prices. Culturally rich but physically demanding.

May/June: Rainy season starts, prices drop sharply, Angkor far less crowded. Green and atmospheric.

July/August: Monsoon high point, some roads flood. Tonle Sap lake at annual high, spectacular for boat tours. Budget-friendly.

September/October: Flooding can increase, some areas hard to reach. Exciting for adventure travelers, less suitable for first-timers.

October/November: Transition, rain easing. Prices still low. Excellent month for coast and islands.
