Best Time to Come

The best time to visit Siem Reap is in December and January, when the days are assuredly sunny and dry. Just be aware that this is the peak tourist season, so you’ll find it more crowded everywhere and prices will be higher.

Seasons

April and May can get very hot in Siem Reap, especially in the latter month when the wetter weather adds a layer of sticky humidity to the high temperatures. From June through November you can expect a lot of rain, but this is not a bad time to visit Siem Reap since the temple sites are less crowded and the surrounding tropical landscape is at its full, fertile green glory. Certainly do bring an umbrella but the rainfall usually comes in brief showers with moments of sun to ensure you’ll be able to take a few good photos of Angkor Wat and beyond!
