Cambodia Climate in March

March marks the beginning of the hot season in Cambodia, a transition period when temperatures steadily climb in anticipation of April’s intense humidity. While some consider other months the best time to visit Cambodia for cooler temperatures, March offers a unique blend of sunshine and fewer crowds. You’ll experience a distinct shift from the dry season as the country transitions towards summer.

In the cultural heartland of Siem Reap, the average temperature in March is 30°C (86°F). However, afternoon highs can reach a sweltering 34°C (93°F), with historical data sometimes showing peaks as high as 38°C (100°F). It is crucial to plan outdoor activities for the cooler mornings and evenings. Relief comes at night when temperatures dip to around 25°C (77°F), although they have been known to stay as high as 28°C (82°F) on occasion. Humidity levels in Siem Reap begin to rise in March, averaging around 70-75%, making the heat feel more intense. These temperature readings are averages based on historical data from the Cambodian Ministry of Water Resources and Meteorology, but do keep in mind the actual temperature can vary slightly year on year. Of course, visiting the temples is a must, but there are many other things to do in Siem Reap, from exploring the bustling local markets like Psah Chas (Old Market) to taking a traditional Apsara dance class or enjoying a relaxing sunset cruise on Tonle Sap Lake.

Along the coast, Sihanoukville experiences similar heat, with daytime temperatures averaging 32°C (90°F) and nighttime lows around 26°C (79°F). The humidity is more pronounced in coastal areas, often reaching 80% or higher, making the air feel even warmer. If you are visiting the southern coast, keep an eye out for the diverse birdlife, including migratory species that pass through Cambodia during this time. The mangrove forests are also teeming with life, and you might spot various species of crabs, mudskippers, and other fascinating creatures adapted to this unique ecosystem.

For those seeking respite from the heat, the northeastern provinces of Mondulkiri and Ratanakiri offer a cooler climate. Here, the average temperature hovers around 26°C (79°F), thanks to the higher elevation and lush forests. This makes March a great time for trekking as you will be able to see the various flora and fauna that thrive at this time of year, such as the beautiful red-flowered Bombax ceiba trees that bloom in March, or spot rare wildlife like the giant ibis.

While March is predominantly dry, characterized by abundant sunshine and clear skies, you might encounter occasional brief showers. These “mango showers,” as they are sometimes called, are typically short-lived and do little to disrupt travel plans. Rainfall amounts are minimal, averaging only around 20-50mm for the entire month in most regions, with Siem Reap historically receiving around 25mm and coastal areas like Sihanoukville closer to 50mm. As a traveler, these conditions are favorable. In addition to dry conditions, there will be fewer crowds, which make this one of the best times to visit Cambodia.

It’s worth noting that global climate patterns like El Niño and La Niña can influence Cambodia’s weather. During an El Niño year, March may experience even hotter and drier conditions than usual. Conversely, a La Niña year might bring slightly cooler temperatures and a small increase in rainfall. While these effects are not always drastic in March, they are a factor to consider when planning your trip. You can check the latest forecasts from international meteorological organizations for the most up-to-date information on the current El Niño/La Niña status.

Key Takeaways:

• Siem Reap: Average 30°C (86°F), highs of 34°C (93°F) (historical peaks of 38°C/100°F), lows of 25°C (77°F) (sometimes staying at 28°C/82°F). Humidity: 70-75%. Rainfall: ~25mm.
• Sihanoukville: Average 32°C (90°F), lows of 26°C (79°F). Humidity: 80%+. Rainfall: ~50mm.
• Mondulkiri/Ratanakiri: Cooler, average 26°C (79°F).
• Rainfall: Minimal, around 20-50mm for the month, with occasional short showers.

Due to these high temperatures, travelers are encouraged to plan outdoor activities for the cooler early morning or late afternoon hours. This is a great time to explore the best Cambodia private tours to discover the beauty and avoid the high heat of the day.

Best Places to Experience Cambodia’s Sunshine in March

March in Cambodia offers glorious sunshine and minimal rainfall, making it an excellent time to explore the country’s diverse landscapes. However, with high UV levels, remember to apply sunscreen regularly, wear a hat, and carry an umbrella for optimal sun protection. While the heat is a factor, the upside is noticeably fewer crowds compared to the peak season.

Here’s a guide to some of the best places to visit in Cambodia during March, making the most of the weather:

1. Angkor Wat and Siem Reap: Sunrise Spectacles and Temple Exploration

High temperatures in March urge tourists to visit Angkor Wat at its best time of the day: sunrise.

While the midday heat can be intense, March offers a unique advantage for visiting the magnificent Angkor Temples: thinner crowds. To beat both the heat and the remaining tourists, plan your temple excursions for the cooler hours of sunrise and late afternoon. Witnessing the sunrise over Angkor Wat is a truly magical experience, and the softer light during these times creates stunning photographic opportunities.

• Insider Tip: Explore Angkor Thom, Ta Prohm (the “Tomb Raider” temple), or Banteay Srei in the early morning or late afternoon when they are less crowded and the temperatures are more manageable. Many consider these temples among the 10 interesting attractions in Cambodia besides Angkor Wat.
• Midday Break: Retreat to air-conditioned restaurants in Siem Reap for lunch, relax by your hotel pool, or indulge in a traditional Khmer massage to rejuvenate for your next adventure.

2. Mondulkiri and Ratanakiri: Jungle Treks and Waterfall Adventures

Dry weather and little or no rain in March creates a great time for adventurous travelers to head into the jungles of Mondulkiri and Ratanakiri, where trekking paths are more accessible and fewer mosquitos. Here, you can explore the unique flora and fauna of the region, such as the beautiful red-flowered Bombax ceiba trees that bloom in March, or spot rare wildlife like the giant ibis. March is also an excellent time to witness the vibrant blooms of Cambodia’s national flower, the Rumduol (Mitrella mesnyi), a fragrant yellowish-white flower that can be found throughout the country, even in temple complexes and urban areas.

• Explore the Wild: Discover stunning waterfalls like Bou Sra in Mondulkiri or Ou’Sinlair waterfall in Ratanakiri, enjoy the refreshing coolness of the forest, and encounter diverse wildlife. You might even have the chance to meet indigenous communities and learn about their unique way of life. These experiences can be part of our best Cambodia private tours.
• Nature’s Embrace: These provinces offer a welcome respite from the heat of the lowlands, making them perfect for hiking, elephant encounters (ensure ethical practices), and immersing yourself in nature.

3. Kampot and Bokor Mountain: Riverside Relaxation and Mountain Breezes

The charming riverside town of Kampot is a delightful destination in March. Enjoy the laid-back atmosphere, explore the pepper plantations, and take a leisurely boat trip along the Kampot River.

• Escape the Heat: For a refreshing change of scenery, take a day trip to the top of Bokor Mountain. The cooler temperatures and panoramic views provide a welcome break from the coastal heat. Explore the old French colonial hill station and enjoy the refreshing breezes.
• Culinary Delights: Kampot is renowned for its fresh seafood and delicious Kampot pepper. Indulge in flavorful meals at riverside restaurants and savor the local specialties.

4. Kep, Sihanoukville, Koh Rong, and Koh Rong Sanloem: Coastal Bliss and Island Escapes

If you’re dreaming of sun, sea, and sand, March is the perfect time to head to Cambodia’s southern coast. The beaches of Kep, Sihanoukville, and the idyllic islands of Koh Rong and Koh Rong Sanloem are bathed in sunshine, with minimal chance of rain.

• Island Paradise: Whether you’re seeking vibrant beach parties on Koh Rong or tranquil relaxation on Koh Rong Sanloem, these islands offer something for everyone. Dive or snorkel in the crystal-clear waters, explore the underwater world, or simply unwind on pristine beaches. They are also perfect honeymoon destinations in Cambodia.
• Seafood Indulgence: Kep is famous for its fresh crab market. Enjoy a feast of freshly caught seafood right on the beach.

3. Packing Essentials for Cambodia’s March Heat

March in Cambodia means sunshine and heat, so packing smart is essential for a comfortable and enjoyable trip. Here’s a detailed packing list to help you prepare for your Cambodian adventure, whether you’re exploring the Angkor Wat sunrise, trekking in the northeast, or relaxing on Koh Rong beaches.

Tourists should pack plenty of light, airy and bright colored outfits to beat the heat of Cambodia’s weather in March.

Clothing:

• Lightweight and Breathable Fabrics: Pack clothes made from natural fabrics like cotton, linen, and rayon. These materials are breathable and will help you stay cool in the humid weather.
• Loose-Fitting Styles: Opt for loose-fitting shirts, trousers, and dresses. This will allow for better air circulation and prevent clothes from sticking to your skin.
• Respectful Temple Attire: Cambodia has many sacred temples and pagodas, including the magnificent Angkor Wat. To enter these sites, you must dress respectfully. This means covering your shoulders and knees. A lightweight scarf or sarong can be easily carried and used to cover up when needed.
• Long Sleeves and Pants (for Sun and Mosquito Protection): While it’s hot, consider packing a few lightweight, long-sleeved shirts and pants. These can protect you from the strong sun during the day and from mosquitoes in the evenings, especially if you plan on doing any trekking in areas like Mondulkiri or Ratanakiri.

Accessories:

• Wide-Brimmed Hat: A must-have for shielding your face and neck from the sun. Choose one that is packable and breathable.
• Sunglasses: Protect your eyes from the bright sunlight with UV-protective sunglasses.
• Umbrella: A compact travel umbrella can provide shade during the hottest parts of the day and also protect you from the occasional brief shower.
• Reusable Water Bottle: Staying hydrated is crucial in the heat. Carry a reusable water bottle and refill it whenever possible. This is eco-friendly and saves you money.

Footwear:

• Comfortable Walking Shoes: You’ll be doing a lot of walking, especially if you’re exploring the temples. Pack comfortable, supportive walking shoes or sneakers.
• Sandals: Sandals are great for everyday wear and for the beach. Choose a pair that is comfortable for walking and has good arch support.
• Trekking Shoes (if applicable): If you plan to trek in Mondulkiri or Ratanakiri, pack sturdy, waterproof trekking shoes with good ankle support.

Other Essentials:

• Sunscreen: High SPF, water-resistant sunscreen is essential. Apply it liberally and reapply frequently, especially after swimming or sweating.
• Insect Repellent: Mosquitoes can be present, especially in the evenings and in rural areas. Pack an insect repellent with DEET or another effective ingredient.
• Swimwear: Pack at least two swimsuits because you can spend most of the day time  relaxing in the swimming pool to avoid the midday heat. Many luxury hotels in Cambodia offer stunning pool facilities, perfect for unwinding after a day of sightseeing. This is also a must when visiting the beautiful beaches and islands in the southern coastal region.
• First-Aid Kit: A small first-aid kit with essentials like pain relievers, antiseptic wipes, and band-aids is always a good idea.
• Medications: Ensure you bring any prescription medications you require, along with a copy of your prescription.
• Travel Adapter and Converter: Cambodia uses Type A, C, and G power outlets.

Tips for Dealing with the Heat:

• Stay Hydrated: Drink plenty of water throughout the day.
• Seek Shade: Take breaks in the shade during the hottest parts of the day.
• Pace Yourself: Don’t try to do too much in one day, especially in the midday heat.
• Utilize Your Hotel Pool or Air Conditioning: Take advantage of the hotel pool or air conditioning for midday breaks.
