Cambodia In December: Why It’s The Perfect Time To Visit

The Weather in Cambodia in December

December is one of the most pleasant months to visit Cambodia. As the country settles fully into its dry season, you can expect long days of sunshine, very little rainfall, and low humidity, which are ideal conditions for sightseeing, beach trips, and countryside exploration.

Temperatures typically range between 21°C and 30°C (70°F to 86°F), with cooler mornings and evenings offering a refreshing break from the usual tropical heat. It’s the kind of weather that lets you start your day early at Angkor Wat, enjoy an afternoon stroll along Phnom Penh’s riverside, and still feel comfortable dining outdoors at night.

Rain is rare in December, though an occasional light shower might occur in coastal areas early in the month. Overall, the air is crisp, the skies are clear, and the landscapes create picture-perfect scenes whether you’re in the city, jungle, or by the sea.

If you're looking for a time to explore Cambodia without the challenges of extreme heat or unpredictable storms, December delivers nearly flawless weather.

Festivals and Events in Cambodia in December

While Cambodia doesn’t have a major traditional Khmer festival in December, the month still carries a vibrant, festive energy, especially in cities and tourist hubs. The dry season weather creates the perfect backdrop for cultural events, expat celebrations, and island festivities. If you're visiting during this time, you’ll find no shortage of things to experience.

Christmas Celebrations

Though Cambodia is a Buddhist-majority country, Christmas is widely celebrated in tourist areas, particularly in Siem Reap, Phnom Penh, and on the southern islands. Many hotels, restaurants, and cafés put up lights and offer special Christmas Eve or Christmas Day dinners, featuring everything from roast dinners to Khmer-fusion cuisine.

In Siem Reap, the Pub Street area lights up with holiday décor, live music, and a festive crowd. You’ll see Christmas trees, Santa hats, and even the occasional snow machine. It's not a traditional Cambodian celebration, but it does create a warm, joyful atmosphere for travelers craving holiday cheer abroad.

New Year’s Eve

New Year’s Eve in Cambodia is a big deal, especially in tourist hotspots and beach towns. In Phnom Penh, the riverside comes alive with street performances, fireworks, and countdown celebrations. Bars and rooftop venues across the city host themed parties and live music.

For a more relaxed tropical version, head to Koh Rong or Koh Rong Samloem, where beach parties stretch late into the night under the stars. These islands are popular among backpackers, but in December, you'll find a mix of locals, expats, and travelers from all over the world celebrating together.

Local Spirit and Buddhist Calm

Even with all the global festivities, December also offers a quieter, more reflective Cambodian experience. Many Cambodians spend this time reconnecting with family or visiting temples for quiet prayer and reflection, especially in rural areas.

Temples and pagodas are beautiful to visit this time of year. The grounds are clean and serene after the rains, and the cooler temperatures make wandering through sites like Wat Phnom in the capital or Preah Vihear up north even more enjoyable.

Cambodia in December offers the best of both worlds: modern holiday festivities in tourist-friendly areas and peaceful cultural moments for those looking to slow down. Whether you're in the mood for fireworks and dancing or quiet sunsets at ancient sites, there's something for every kind of traveler this month.

Where to Go in Cambodia in December

With clear skies and dry roads, December unlocks access to nearly every corner of Cambodia. From ancient temples in the north to tropical islands in the south, the country is wide open for exploration. Whether you’re drawn to culture, coastlines, or quiet countryside, here are the must-visit destinations for a December trip:

Siem Reap & Angkor Wat

Siem Reap is the crown jewel of Cambodian tourism, and December is one of the best times to visit. The weather is cool at sunrise and warm by midday, and the temple complex is especially stunning under December’s crisp blue skies. Begin your day early at Angkor Wat, then continue to Bayon, Ta Prohm, and the lesser-known but magical Banteay Srei. Crowds are present, especially near Christmas, but not overwhelming if you plan early starts.

Beyond temples, Siem Reap offers vibrant night markets, lively Pub Street, artisan workshops, and countryside tours that take you through rice paddies and small Khmer villages. It’s a cultural hub that still feels authentic, especially in the dry season.

Phnom Penh

Cambodia’s capital is buzzing in December, with dry skies and a cooler breeze making it the ideal time to walk, wander, and reflect. Begin at the Royal Palace and Silver Pagoda, then dive into the country’s more recent history at the Tuol Sleng Genocide Museum and Choeung Ek Killing Fields.

Beyond the landmarks, riverside Phnom Penh is alive with cafés, rooftop bars, and sunset cruises on the Mekong. In December, the city has festive energy, especially around Christmas and New Year, when expat communities host public events and riverside promenades glow with lights.

Sihanoukville & Koh Rong

For beach lovers, Sihanoukville is the coastal gateway to Cambodia’s islands. While the town itself is undergoing rapid development and isn’t as charming as it once was, it’s still the launch point for ferries to Koh Rong and Koh Rong Samloem.

December is prime time for island escapes. On Koh Rong, you’ll find long stretches of white sand, snorkeling tours, and a mix of beach parties and quiet coves. For something more tranquil, Koh Rong Samloem is ideal, home to eco-resorts, no-car beaches, and gentle hiking trails through the jungle and coastline.

Expect clear water, sunny days, and calm seas, making this the perfect month to swim, kayak, or simply unwind with your toes in the sand. Just make sure to book ferries and accommodations early, as December is peak island season.

Mondulkiri

For travelers craving fresh air and untouched nature, Mondulkiri in December is a hidden gem. Tucked away in Cambodia’s eastern highlands, the region is known for rolling green hills, pine forests, and cooler temperatures.

This is a great time to visit the Elephant Valley Project, where rescued elephants roam in natural jungle environments. Hikes to Bousra Waterfall and treks through dense forest trails offer a quieter, more immersive experience. The weather is cool and dry, making it comfortable for outdoor exploration.

Mondulkiri isn’t as developed as other destinations, but that’s part of its charm. It’s perfect for travelers seeking eco-tourism, ethical wildlife experiences, and a deeper connection to Cambodia’s highland communities.

Cost and Crowds

Visiting Cambodia in December comes with clear perks: beautiful weather, full access to remote destinations, and lively cities filled with energy. But as the dry season peaks, so do tourism numbers and prices. It's still affordable compared to neighboring countries, but planning will help you save money and avoid stress.

• Accommodation costs increase, especially in tourist-heavy places like Siem Reap, Phnom Penh, and the islands. Beach resorts and boutique hotels fill up fast during Christmas and New Year.
• Flights book out early and tend to rise in price the closer you get to mid-December, especially for regional connections from Thailand, Vietnam, or Malaysia.
• Top attractions can feel crowded, particularly Angkor Wat, Koh Rong beaches, and the capital’s riverside areas. Expect longer lines and busier photo spots.

Despite the crowds, December is when Cambodia runs at full steam: smooth transport, active tour operators, and vibrant nightlife across key destinations.

Pro tip: Travel during the first half of December for thinner crowds and better hotel deals. Book in advance, especially ferries, domestic flights, and island stays.

What to Pack & Travel Tips for December in Cambodia

Packing for Cambodia in December is refreshingly simple thanks to the dry weather and comfortable temperatures. You’ll want to be ready for long days of walking, temple visits, and perhaps even a tropical island escape. While Cambodia is casual and warm, a few smart choices can make your trip more comfortable and respectful of local customs.

Here’s what you’ll want to bring:

• Lightweight, breathable clothing: Cotton or linen works well for hot afternoons.
• A light jacket or scarf: For cooler evenings or chilly bus rides.
• Comfortable walking shoes: Essential for temples, cities, and the countryside.
• Sun protection: A hat, sunglasses, and high-SPF sunscreen are a must.
• Swimsuit and quick-dry towel: Ideal if you plan to visit islands or stay at hotels with pools.

And some smart travel tips:

• Book early: December is the high season. Reserve hotels, ferries, and domestic flights in advance.

So, Is December a Good Time to Visit Cambodia?

December is one of the best times to visit Cambodia. With the rainy season fully behind, the country enjoys clear skies, mild temperatures, and low humidity. It’s ideal for travelers who want to explore temples, relax on beaches, or enjoy outdoor activities without the discomfort of heat or rain.

The festive energy around the holidays adds to the appeal.
