Volgens de “Lonely Planet” van Cambodia :
When to Go
The ideal months to be in Cambodia are December and January, when humidity is bearable, temperatures are cooler and it's unlikely to rain. From February onwards it starts getting pretty hot, and April is unbearably so. The wet season (from May to October), though very soggy, can be a good time to visit Angkor, as the moats will be full and the foliage lush - but steer clear of the northeast regions during those months, as the going gets pretty tough when the tracks are waterlogged. The country's biggest festival, Bon Om Tuk, is held in early November, and is well worth catching.
