Countries with Dry Weather: Thailand, Vietnam, Laos, Myanmar, Cambodia, and the Philippines
If you're planning to travel to multiple countries in (northern) Southeast Asia, December is undoubtedly the best time to explore them. You'll have the most favorable weather with rain-free days and cool/mild temperatures.
With that comes the high costs and crowds, especially over the Christmas and New Year periods. For your family reunions or milestone celebrations, booking 6 months in advance is recommended to have more availability of the best hotels and avoid last-minute hassles.

Bangkok and Chiang Mai
In Bangkok, our guide Ann and driver "Mr. Ot" (I don't know how to spell his name) were very friendly and professional. You simply can't underestimate the value of having an English speaking guide to show you around, and a driver with a comfortable, sizeable, air-conditioned van take you from place to place. Ann taught us so much about Thailand's history, food, and religion. Mr. Ot always opened our door with a smile, and had cool towels and ice-cold bottled water for us. More

Excellent guide in Siem Reap
Our recent time spent in Siem Reap was made even more memorable by our expert guide, Som Piseth. Som was knowledgeable, attentive, flexible and super helpful - we learnt so much about Siem Reap and Cambodia in our 3 days with him. His English was excellent and his knowledge of, and pride in, his country was outstanding. We would highly recommend Som for anyone wanting an excellent guide in Siem Reap! More

Costs and Crowds in December
December is a popular time to visit Southeast Asia, especially for a warm winter getaway. You should expect higher costs and crowds in the dry countries, such as Thailand, Vietnam, and Cambodia. Early December is ideal to enjoy these countries because of the good weather and fewer crowds.
To avoid the rocketing prices of hotels and flights, it's advisable to book 6 months in advance. Despite the increased crowds, the festive atmosphere and pleasant weather make it an enjoyable time to explore the region.
Conversely, the rainy season in Singapore, Malaysia, and Indonesia offers tranquility and cost-effective travel options.

What to Pack in December
When packing for your Southeast Asia trip in December, you're advised to take lightweight and breathable clothing that's suitable for mild/warm weather. If you visit northern Vietnam, northern Thailand, or mountainous areas, a coat is helpful as the temperature might drop to 15°C (70°F). Also, take your swimsuits and beachwear if you want a beach vacation.
Sun protection is necessary for the high UV rays so don't forget to pack sunscreen, sunglasses, and a hat, etc.
When you visit countries that have their rainy season, it's always good to be prepared with a compact raincoat or umbrella.
To avoid potential mosquito bites, pack an insect repellent to stay protected.
