Cambodia weather in December is generally drier and more comfortable than the rainy months, with northeast winds bringing cooler air and reduced precipitation. Travelers typically find this month easier for visiting temples, cities, and beaches thanks to lower rainfall and long daylight hours.
What December weather in Cambodia looks like
December sits at the start of Cambodia’s dry season, when the country receives fewer rain showers and humidity eases compared with the monsoon period. Visitors report daytime temperatures that are pleasant for walking and outdoor activities, while evenings—especially in northern and inland areas—can feel noticeably cooler.
Typical climate figures cited by travel sources put average daily temperatures in a broad band. Coastal and southern locations usually register the warmest daytime highs, while northern highlands and inland cities can see cooler mornings and nights. Rain is uncommon in most places during December, though occasional short showers may still occur.
Regional differences and highlights
Cambodia’s climate varies between the north, central plains, and southern coast. In the north—around areas such as Ratanakiri and the Angkor region—many visitors notice crisp mornings and bright, mild days that suit temple visits and countryside drives. Phnom Penh and other central areas offer warm, dry weather ideal for city sightseeing and riverside walks.
The southern coast and offshore islands remain warmer through December. Beaches near Sihanoukville, Koh Rong and Koh Rong Sanloem typically have comfortable sea temperatures and extended daylight for swimming and boat trips. While southern spots are warmer overall, humidity can still be noticeable on sunnier days.
- North: cooler mornings, crisp daylight hours—good for temple touring.
- Central plains: warm, dry conditions for city sightseeing.
- South and islands: warm sea temperatures, suitable for beach activities.
Practical tips for traveling in December
Because December is within the high season, services and accommodation can book up quickly; it is prudent to reserve hotels, domestic transport and guided visits well in advance. Many families travel at year-end, so peak dates around holidays may see higher prices and busier attractions.
Sun protection remains important even in cooler air: apply sunscreen, wear a hat, and carry water for longer excursions. Light layers work best—mornings and evenings inland may need a light jacket, while daytime on the coast calls for breathable clothing.
- Book core services early to secure preferred hotels and tours.
- Pack lightweight layers and reliable sun protection.
- Carry a refillable water bottle and stay hydrated in warm weather.
- Be ready for short, unexpected showers despite the overall dry trend.
Cultural context and seasonal events
December coincides with increased local and tourist activity as people travel for holidays and festivals at year-end. Visitors typically find more open shops, restaurants and events than during the wet season. Traditional sites, markets, and public spaces can be lively during holiday periods.
When planning visits to religious sites and public ceremonies, respect local customs such as modest dress at temples and quiet conduct during rituals. Peak-season crowds at major attractions like Angkor Wat are common, so consider early-morning starts to avoid the busiest hours and heat.
- Expect fuller tourist facilities and special holiday events in December.
- Dress conservatively at temples and follow local etiquette.
- Start major visits early to beat crowds and midday heat.
Who benefits most from a December trip
Travelers prioritising reliable weather for outdoor sightseeing and beach time tend to prefer December. Families and groups travelling over the Christmas and New Year period often choose this month because of the drier conditions and festival atmosphere in towns and resorts.
Those looking for quieter travel will still find options—smaller coastal towns and inland villages are less crowded than the main tourist hubs—but should plan carefully to avoid the busiest holiday dates if they want lower rates and fewer people at attractions.
- Ideal for: temple visits, city tours, beach stays, and photography.
- Less ideal for: travellers seeking absolute solitude in major tourist spots during peak holiday dates.
Comparisons and alternatives
For those weighing travel months, December offers a clear contrast with the wet season months such as July, when frequent heavy afternoon rain is expected. Comparing conditions can help choose between a rainy-season bargain and the more predictable dry-season experience.
If your travel dates are flexible, consider whether you prefer quieter shoulder months (November or April) or the reliably dry peak months in winter. For a perspective on how the wet season behaves in Cambodia, many readers consult guides about Cambodia’s wet season to weigh trade-offs in activities and costs.
