Dress Code: Cambodia geographically stays in the tropical monsoon; its weather varies and annually brings wet and dry seasons, generally hot during day time and a bit cooler at night, and in the early morning. You should wear whatever is most comfortable but remember to dress appropriately to respect the locals and other religious sites: pagodas, temples and holy places. Clothes must cover your shoulders and knees when you wish to visit the top part at Angkor Wat, Royal Palace in Phnom Penh and when you go to meet Buddhist monks.
