It is such a high order to answer the question: “What is the best time to travel to Vietnam?” Actually, there is not really a right or wrong time to visit Vietnam as its weather varies from one region to another due to the country’s different location lapping on variety of tropical region. For that reason, when researching weather for your intended visiting Vietnam, you should imagine the country as three separate groups of destinations, which are the North, the Center and the South of Vietnam.
Asking yourself what is the best time to visit Vietnam and the North East Vietnam including Hanoi has a distinct winter and summer season. The winter lasts from November to April the temperatures average 17 – 22 °C, you can see the most colorful festivals, especially Tet Holiday in late January and early February. In summer, the period from August to October is the ripe time for you to discover a lot of stunning mountainous destinations such as Halong Bay, Trang An – Ninh Binh and Ba Be Lake – Bac Can.

If you are kind of an adrenaline junkie who loves trekking and adventure, so the period from September to November and from March to May is definitely the best time to travel to Vietnam in order to explore the marvelous and picturesque panorama of the North West mountains such as Ha Giang, Sapa, Cao Bang and Dien Bien Phu. And remember not to travel to the north-east in the wet season from May to September, because it can get very cold and humid.
Turning to the Central Vietnam, the best time to travel to Vietnam for you is between September and December, when interesting destinations such as Hue, Hoi An and Da Nang receive considerable rain. At the far south of Central Vietnam, Nha Trang with its magically beautiful beaches benefits from a longer dry season (typically January to September), with high temperatures and little rain.
Finally, South Vietnam (including Saigon and Mekong Delta) benefits from a long dry season, so the best time to travel to Vietnam in the South is between December and May when the skies are clear, the land and scenery are incredibly lush and the waters on the Mekong Delta are very calm. The showers during monsoon season are generally short and sweet and certainly shouldn’t deter you from travelling. If you’re in Saigon during these quite spectacular showers, you’ll be wowed by how quickly the water dissipates due to very impressive drainage and then it is blue skies again.
