Cambodia's temperatures stay pretty constant all year round with a distinct wet and dry season. The north generally experiences slightly colder winters (dry seasons) than the south. The most popular season to travel, by far, is the dry season, as showers usually only occur in the late afternoon and for a matter of minutes before passing over. In the wet season, however, rainfall can be constant and heavy, with August and September bringing most of the monsoon rains to the whole country. That shouldn't put you off, though – the Angkor temples and terraced rice fields arguably look the best after a shower and without the smoky haze of the dry season. Plus, it's generally much quieter in the wet season.
