Good time to Ttravel Vietnam is from September to June. However, Vietnam has three different regions – the North, the Central and the South – each with different weather patterns and different rainy seasons. This means that there is neither a best time nor a worst time to visit Vietnam. Hot summer or cold winter is not that a big deal. Beaches such as Halong bay, Hoi an, Nha trang, Mui ne - Phan thiet, Phu quoc are always available. Sapa and Dalat highland offer great places for cool temperature. You can find your favourite kind of weather all year round!
