Because of the warmth and humidity all year round it is important to pack lightweight clothing made of natural and breathable fabrics. However, if you’re planning to visit the mountainous central highlands you will need some warmer clothes because it can get quite a lot cooler there, so think about adding some layers, also be prepared for showers at any time of year.
It is important when visiting religious buildings, such as Buddhist and Hindu temples, that you must have your knees and shoulders covered and all headwear and shoes removed. The temple floors can get hot underfoot so carrying some socks to protect your feet is a good idea.
