The climate in HCMC is subtropical. The climate is mostly subtropical and moderately humid for much of the year, which is perfect for outdoor dinner parties, night walks, and poolside lounging. Problems with dry skin and eyes are virtually unheard of but if you're looking for snow, you won't find it here. If you're from a place where winter literally kills and you'd love a summer day, then this is the place to be. Teasing friends about shovelling snow back home is a common pastime among grinning expats. And if you burn easily? Make sure you bring some sunscreen.
