The dry season runs from November to April, while the wet season runs from May to October. If you’re planning to visit Siem Reap during the dry season, expect bright sunny days with little to no rainfall. Temperatures can reach up to 35°C (95°F) during the day, so be sure to pack light, breathable clothing.

What is the best time to visit Siem Reap?
The best time to visit Siem Reap largely depends on your personal preferences and travel goals. However, the most popular time to visit is during the dry season, which runs from November to April.
