Stone Temples, Reversing Rivers: A Year in Cambodia

Angkor’s sandstone towers, Tonle Sap’s shape-shifting lake, and a coastline that runs on its own calendar — here’s how Cambodia’s year actually unfolds.

Cambodia’s calendar runs on the same monsoon rhythm as much of Southeast Asia, but it has one genuinely unique feature: the Tonle Sap, a lake connected to the Mekong by a river that actually reverses its flow direction twice a year. That single detail changes what’s worth seeing and when, far more than temperature alone.

Cambodia’s Year at a Glance

The Tonle Sap actually swells to several times its dry-season size as the Mekong pushes water back into it each monsoon.

Season by Season

Nov – Feb · Cool & Dry Season

Peak Season for Temples and Coast Alike

This is Cambodia’s most comfortable and most popular stretch — lower humidity, minimal rain, and the clearest light for photographing Angkor’s sandstone towers at sunrise.

First-time visitors: Siem Reap and the Angkor temple complex are at their most comfortable for a multi-day exploration in this cooler window, especially for early starts at Angkor Wat itself.
Beach travelers: Sihanoukville and the nearby islands, including Koh Rong, have calm seas and reliable boat schedules through this period.
Families: Phnom Penh’s Royal Palace and Silver Pagoda are easy, walkable stops in the mild winter air.

Mar – May · Hot Season

Warm Days, Early Starts

Heat and humidity climb through this stretch, making early morning the only truly comfortable window for temple exploring, with afternoons better spent indoors or by the coast.

Temple visitors: plan Angkor Wat and Angkor Thom visits for sunrise or late afternoon, treating the midday hours as a break rather than pushing through the heat.
Coastal travelers: the islands remain a comfortable option in this season, often with sea breezes offsetting the inland heat.

Jun – Oct · Monsoon Season

Lush Jungle Temples and a Transformed Lake

Rain typically arrives in short, heavy afternoon bursts rather than constant drizzle, and this is genuinely the best season for two very specific experiences: Ta Prohm’s jungle-strangled ruins at their greenest, and the Tonle Sap at its largest and most dramatic.

Nature enthusiasts & photographers: Ta Prohm’s famous strangler fig trees are at their most vivid and atmospheric against the rainy season’s deep green backdrop.
Adventurous travelers: the Tonle Sap swells to several times its dry-season size by August through October, making floating villages and flooded forest more accessible by boat than at any other time of year.
Practical note: island and coastal boat schedules can be disrupted by rough seas in peak monsoon months, so build flexibility into any Sihanoukville or island leg during this window.

Tastes of Cambodia: What to Eat

Beyond the Neighboring Cuisines

Fish amokCambodia’s national dish — a steamed coconut curry, traditionally served in a banana leaf bowl, mild and aromatic rather than intensely spicy.

Lok lakStir-fried marinated beef served over lettuce and rice, with a distinctive lime-and-pepper dipping sauce.

Num banh chokKhmer noodles topped with a fish-based green curry sauce, traditionally eaten as a breakfast dish.

Kampot pepperGrown in the region around Kampot and considered among the best pepper in the world — worth trying fresh rather than as a souvenir tin.

Cambodian iced coffeeStrong coffee over ice with sweetened condensed milk, a reliable pick-me-up between temple visits.

Palm sugar treatsMade from sap tapped from sugar palms, sold at roadside stalls especially around Kampong Thom.

Know Before You Go: Practical Tips

Beyond the Itinerary

Angkor temple dress codeShoulders and knees covered at Angkor Wat and other active temple sites, since these remain functioning religious spaces.

Angkor pass optionsPasses are typically sold as 1-day, 3-day, or 7-day options — a 3-day pass gives enough time to see the major temples without rushing.

Visiting the Killing Fields & Tuol SlengThese are solemn genocide memorial sites in Phnom Penh — quiet, respectful behavior is expected, and photography should be handled with care.

Currency in daily useBoth Cambodian riel and US dollars circulate side by side, with USD commonly used for larger purchases and riel for small change.

Staying on marked pathsIn some rural areas away from tourist routes, unexploded ordnance remains a real historical legacy — stick to marked paths and trails outside well-established tourist areas.

Tuk-tuk faresAgree on a price before the ride, particularly for longer trips like temple-hopping around Siem Reap.
