Cambodia has two types of weather: hot, and hot and wet. So before we get into what to wear, the first thing to do is figure out which season you’re travelling in – wet or dry?
If you’re travelling between November and May, your main consideration will be staying cool during scorching days and muggy nights. Fabrics like linen or cotton and athletic wear made to repel sweat are appropriate. While you’ll experience some rain during this period, it will likely come in the form of light showers that pass quickly.
If you’re travelling from June through to the beginning of November, you’ll want to pack all of the above plus a raincoat and clothes that won’t go totally see-through if you get wet (which is inevitable).
