Cambodia In August: Island Hopping And Weather Tips

Cambodia is a stunning destination year-round, but August presents a unique blend of adventure, natural beauty, and cultural experiences. While it falls within the monsoon season, don’t let that deter you—there’s still plenty to enjoy, especially if you’re interested in island hopping, exploring less crowded attractions, and soaking in the lush landscapes.

This guide covers everything you need to know about visiting Cambodia in August, from the weather to the best islands to visit and essential travel tips.

Weather in Cambodia in August

August is part of Cambodia’s rainy season (May to October), bringing warm temperatures, high humidity, and frequent rain showers. However, these rains often come in short, heavy bursts, usually in the afternoon or evening, leaving plenty of time to explore during the day.

What to Expect:

• 🌡️ Temperature: 25°C – 33°C (77°F – 91°F)
• 🌧️ Rainfall: Frequent showers, particularly in the afternoons
• 💨 Humidity: High (around 80%)
• 🌞 Sunshine: Intermittent sunny spells between showers

Despite the rain, August is a fantastic time for nature lovers. The countryside is lush and green, waterfalls are at their peak, and the temples of Angkor Wat look even more mystical in the moody, misty weather.

There is no such thing as bad weather, only inappropriate clothing.

Island Hopping in Cambodia: Best Islands to Visit in August

Cambodia’s coastline is home to beautiful islands, offering pristine beaches, coral reefs, and tropical retreats. While the monsoon season brings rougher seas, several islands remain accessible and enjoyable.

Koh Rong – The Party & Adventure Island

Best for: Backpackers, nightlife, and adventure seekers
Koh Rong is Cambodia’s most famous island, known for its vibrant nightlife, stunning beaches, and adventure activities. While some boat services may be limited due to rough waters, you can still visit by speedboat from Sihanoukville.

• Things to Do:
  • Explore Sok San Beach (quieter, with powdery white sand)
  • Try bioluminescent plankton night swimming
  • Go zip-lining or jungle trekking

Weather Tip: Be prepared for occasional rain and choppy boat rides; avoid small long-tail boats in rough seas.

  • Kayak through the mangroves

Weather Tip: Some boat transfers may be delayed due to storms, so check schedules in advance.

Koh Ta Kiev – The Off-the-Grid Hideaway

This lesser-known island offers a rustic, off-the-grid experience with eco-lodges, no Wi-Fi, and a strong connection to nature. It’s a great choice for travelers looking to disconnect.

• Things to Do:
  • Hike through the jungle trails
  • Camp under the stars
  • Visit the glowing plankton at night

Weather Tip: Bring waterproof gear, as heavy rains can make dirt paths muddy.

• Things to Do:

Travel Tips for Visiting Cambodia in August

Pack for the Rain

Since August is a wet month, pack light, quick-dry clothing and waterproof essentials:
✔️ Rain jacket or poncho
✔️ Waterproof bags for electronics
✔️ Lightweight clothing to deal with humidity
✔️ Good hiking sandals or waterproof shoes

Be Flexible with Plans

Heavy rains can sometimes cause delays in transportation, especially ferries and flights. Have a flexible itinerary and allow extra travel time.

Take Advantage of Fewer Crowds

August is considered Cambodia’s low season, which means fewer tourists and lower accommodation prices. This is a great time to enjoy famous spots like Angkor Wat and the islands without crowds.

If boat rides become difficult due to rough seas, explore Cambodia’s mainland attractions:

• Angkor Wat: The temples look stunning with rain-kissed stones and dramatic clouds.
• Kampot: Visit pepper farms and cruise down the river.
• Battambang: Enjoy art, culture, and the famous Bamboo Train.

Book Accommodations with Good Infrastructure

Choose hotels or resorts with reliable drainage, backup power, and good shelter from storms, especially on the islands.
