What's the weather like in Cambodia in May?Cambodia is a stunning country in Southeast Asia, bordering Vietnam to the east and Thailand to the north-west. It has a monsoon climate which brings warm weather all year round, as well as distinct wet and dry seasons. In May, the hot, dry spring is turning into the wet summer across much of Cambodia, and there can be lots of rain in some parts of the country. If you don’t mind working around the downpours, the wet season can be a beautiful time to visit Cambodia, with the fresh air and striking landscapes.
