How hot is it in Cambodia during December?

December is typically the coolest month in Cambodia, although we use the term cool in a relative sense! Expect heat, with the temperature hitting about 31℃ during the day, falling away to a balmy 22℃ at night.The UV index will be high at this time of year, so protection against skin and eye damage is needed. Try to limit exposure between 10am and 4pm. Apply broad spectrum SPF 30+ sunscreen every few hours, even if it's cloudy, or more frequently after sweating or swimming, and wear UV-blocking sunglasses too, and bear in mind that bright surfaces, such as sand and water increase UV exposure.

Does it rain in Cambodia during December?

On average, there will be 2 rainy days during the month, amounting to 64.7mm in total. That's broadly comparable with the amount of rain we see in England during the summer months, and would be considered dry. There's a small chance that you'll catch a thunderstorm during your trip.

Is it windy in Cambodia during December?

You're unlikely to experience any strong winds. Expect a light breeze that picks up slightly at times in December. With moderate humidity, any breeze will have a welcome cooling effect.
