Vietnam weather changes a lot from north to south. The best time to visit depends on your route, because Hanoi, Ha Long Bay, Da Nang, Hoi An, Ho Chi Minh City and the Mekong Delta do not always have the same weather patterns.
Use this climate calendar as a quick planning guide. Vietnam can be visited all year, but February to April and November are often the easiest months for a broad trip across several regions.
Best months: February March April November
February to April and November are often the easiest months for a broad Vietnam trip.
Hanoi, Ha Long Bay and Sapa are often more comfortable in spring and autumn.

The best time to visit Vietnam for a broad trip is usually from February to April and around November. These months often offer a good balance between comfortable weather, lower rain risk and easier travel across several regions.
Vietnam is long and narrow, so weather can be very different between the north, the center and the south. A good month for Hoi An may not be the best month for Sapa or Phu Quoc.
If your route includes Hanoi, Ha Long Bay, Hoi An, Ho Chi Minh City and the Mekong Delta, spring is often one of the easiest periods to plan around.
