Understanding Cambodia’s climate

Cambodia has a tropical monsoon climate, characterized by two distinct seasons: the dry season (November to April) and the wet season (May to October). Temperatures stay warm year-round, typically between 25°C and 35°C, but humidity and rainfall vary dramatically throughout the year.

Dry season in Cambodia (November to April)

The dry season in Cambodia is marked by clear blue skies, low humidity (around 50–65%), and temperatures ranging from 25°C to 32°C, making it the most popular time to visit. It’s divided into two parts: the cool dry season from November to February and the hot dry season from March to April.

During the cool months, the weather is comfortably mild and breezy. perfect for sightseeing, temple exploration, and outdoor activities. From March onward, temperatures rise sharply, especially in Phnom Penh and Siem Reap, where midday heat can exceed 35°C. Rain is rare throughout the season, though UV levels remain high from late morning to mid-afternoon. The northeast monsoon dominates this period, bringing dry, pleasant air and ideal travel conditions across most of the country.

Wet season in Cambodia (May to October)

The wet season transforms Cambodia into a lush, vibrant landscape. Afternoon showers bring the countryside to life, refreshing rice fields and forests while keeping the air cool and clear. Despite the rainfall, mornings are often dry and bright, allowing plenty of time for exploration before the clouds roll in.

Rain typically arrives in short, heavy bursts, followed by sunshine, making travel easier than many expect. Temperatures range between 26–31°C, with higher humidity and greener scenery. Occasional thunderstorms may bring lightning or brief gusty winds, and while puddles can form on unpaved roads, most routes remain passable. River levels rise, creating ideal conditions for boat trips and floating village visits, revealing a side of Cambodia that feels both peaceful and alive.

What to do in Cambodia by season?

Best destinations and things to do in Cambodia during the dry season

Siem Reap

Cool mornings and dry trails make this the ideal moment to witness Angkor Wat at sunrise, when soft golden light reveals the majesty of the world’s largest religious monument. Explore Ta Prohm, where giant roots embrace ancient stone corridors, and Bayon, famous for its serene smiling faces. Cycling through these temples in the dry season is comfortable and photogenic, with fewer puddles and clearer visibility than during the raining season in Cambodia.

On Koh Rong Sanloem, serene Saracen Bay offers quiet luxury and sunset walks, while Koh Rong buzzes with beach bars, jungle treks, and water sports. With daily ferries operating reliably, these islands feel like the ultimate reward for a tropical winter getaway.

Inland, the Mondulkiri region offers a refreshing contrast to Cambodia’s lowlands. During the dry months, roads are easier to navigate, and misty mornings reveal rolling pine-covered hills and cascading waterfalls. Visit the Elephant Valley Project, an ethical sanctuary where visitors can observe rescued elephants roaming freely through the forest, an inspiring reminder of conservation and compassion.

As sunset paints the Mekong in shades of gold, you’ll experience the serene rhythm of rural Cambodia.

Festivals in Cambodia during the dry season

Long, narrow racing boats representing different provinces compete on the Tonle Sap River, accompanied by fireworks, lanterns, and lively street celebrations. It’s a spectacular cultural moment that celebrates the life-giving power of Cambodia’s waterways.

Siem Reap in green

After a rain shower, Angkor Wat and its surrounding temples take on a deeper, more mysterious beauty. Moss carpets the ancient stones, moats overflow, and clouds create dramatic contrasts in photos. Explore the outlying temples like Banteay Srei or Beng Mealea, where you’ll find fewer visitors and more serenity among the ruins.

Tonlé Sap at high water

From July to September, the Tonlé Sap Lake swells to several times its dry-season size. Boat trips glide through flooded forests and floating villages, offering an intimate glimpse into Cambodia’s river-based lifestyle. It’s one of the most authentic experiences to have during the Cambodia best time to go for cultural immersion.

Kampot & Kep

The coastal towns of Kampot and Kep shine during the wet months with misty river views, moody sunsets, and tranquil vibes. Visit pepper plantations, explore colonial streets between rain showers, and savor ultra-fresh seafood pulled straight from the Gulf of Thailand. The cooler air and softer light make these destinations ideal for relaxation and slow travel.

Cafés & Cooking Classes in Phnom Penh

Rainy afternoons are the perfect excuse to slow down and indulge indoors. Settle into stylish cafés in Phnom Penh or Siem Reap, or join a Khmer cooking class to learn traditional recipes like amok or loc lac. Between sips of coffee and fragrant spices, you’ll find that Cambodia’s warmth comes as much from its people as from its tropical sun.

Travel tips for every season in Cambodia

Whether you visit during the dry or wet season, these practical tips will help you travel smoothly and enjoy Cambodia in every condition.

Protect yourself from the sun

The tropical sun can be intense even on cloudy days, especially from March to April, when temperatures peak. Apply SPF 50+ sunscreen, wear a hat and breathable long sleeves, and drink plenty of water. Fresh coconut water or sugarcane juice are great natural ways to stay hydrated while exploring.

Carry cash in small notes

US dollars are widely accepted throughout Cambodia, but make sure your notes are clean and undamaged as old bills may not be accepted. Carry small denominations (USD 1–10) for tuk-tuks, local markets, and street food stalls. You may receive change in Cambodian riel, so keep an eye on conversion rates. ATMs are easy to find in major cities like Phnom Penh and Siem Reap, but are limited in rural areas, so withdraw enough cash before heading off the beaten path.

Dress respectfully at temples

When visiting sacred sites like Angkor Wat or Wat Phnom, wear clothing that covers your shoulders and knees. Remove hats and shoes before entering pagodas. A light scarf is handy for both sun protection and modesty.

Be flexible with weather

If you’re traveling during the raining season in Cambodia (May–October), remember that showers are often brief and followed by sunshine. Use the downtime to relax in a café, visit a museum, or browse an indoor market. After the rain, the light turns golden and the landscapes come alive, ideal for photography and peaceful exploration.

Connect with the Khmer locals

Cambodians are warm, welcoming, and proud of their culture. Learn a few simple Khmer phrases like “Chum reap suor” (hello) and “Orkun” (thank you). Supporting local artisans, guides, and family-run restaurants helps strengthen community-based tourism and creates genuine cultural connections.

Stay safe and covered in Cambodia

Always travel with insurance that includes medical coverage and trip protection. Keep digital and paper copies of your passport, and bring essentials like bottled water, snacks, and a power bank for long journeys. During high season (November–February), plan early to avoid overbooked accommodations or crowded routes. When venturing into remote border areas, stay updated on local advisories and travel with licensed guides for peace of mind.

Easy travel from Singapore to Cambodia

Traveling from Singapore to Cambodia is simple and seamless, making it one of the most convenient gateways to Indochina. Direct flights (Singapore Airlines, AirAsia, Emirates) connect Singapore with Phnom Penh and Siem Reap in just about two hours, allowing travelers to enjoy a spontaneous weekend escape or start a longer regional journey. With almost no time difference, you can step off the plane and begin exploring right away.

Cambodia visa policies for foreigners

Beyond Cambodia, where should you go as well?

Many travelers also choose to combine Cambodia with Vietnam or Thailand, as frequent short-haul flights make multi-country itineraries smooth and affordable.
