December Weather in Cambodia
Is December Right for You?
Advantages
- Peak dry season with only 3 rainy days and 45mm (1.8 inches) rainfall - perfect for Angkor temple exploration and outdoor activities
- Coolest temperatures of the year at 22-30°C (72-86°F) with 65% humidity, making long walks and cycling comfortable from sunrise to sunset
- Crystal clear skies provide optimal photography conditions at Angkor Wat, with stunning sunrises and golden hour lighting lasting longer due to dry air
- Tourist numbers drop 40% after Christmas week, creating peaceful temple experiences while weather remains perfect through New Year
Considerations
- Accommodation prices peak 60-80% higher during Christmas/New Year weeks (Dec 20-Jan 2), with best hotels booking out 3+ months ahead
- Dusty conditions from months of dry weather require daily face washing and can irritate sensitive sinuses, especially on dirt roads to remote temples
- UV intensity reaches dangerous levels (index 8) with minimal cloud cover - sunburn happens in 15 minutes without SPF 50+ protection
Best Activities in December
Angkor Archaeological Park Temple Cycling
December's cool mornings (22°C/72°F) make cycling between temples comfortable until 10am. Dry roads mean no mud, and clear skies create perfect lighting for photography. The 25km (15.5-mile) grand circuit is actually enjoyable in December's weather, unlike the sweltering heat of hot season.
Tonle Sap Lake Floating Village Tours
December's low water levels reveal the lake's seasonal transformation - floating houses sit on stilts, and you'll see how communities adapt. Comfortable 28°C (82°F) temperatures and minimal rainfall make the 2-3 hour boat trips pleasant, with excellent visibility for wildlife spotting.
Phnom Penh Historical Walking Tours
The capital's intense heat becomes manageable in December's cooler weather. Walking tours covering Royal Palace, S21, and Russian Market are comfortable in morning/late afternoon. December's clear skies provide dramatic lighting for the sobering historical sites, and reduced humidity means less exhaustion during emotional visits.
Kampot Province Countryside Exploration
December's dry season opens rural roads impassable during rains. Cool mornings perfect for cycling through pepper farms, and low humidity makes Bokor Mountain's 1,000m (3,280ft) elevation comfortable. The Kampot River is at ideal levels for kayaking, with gentle currents and clear water.
Siem Reap Food Market Tours
December's comfortable temperatures make hot street food enjoyable again. Local markets like Phsar Leu and Old Market are less stifling in 65% humidity vs. rainy season's 85%. Traditional hot pot and BBQ dishes - avoided in hot season - become appealing in December's cooler evenings.
Koh Rong Island Day Trips
December brings Cambodia's clearest seas - visibility reaches 15m (49ft) for snorkeling. Calm waters and consistent breezes make the 1-hour boat ride from Sihanoukville comfortable. Beach temperatures of 30°C (86°F) are perfect for swimming, and minimal rainfall means reliable ferry schedules.
