Best Time To Visit Hanoi > Weather, Temperature & Season

What is the best time to visit Hanoi?

The best time to visit Hanoi is October to April, and the two best windows inside that are February to April and October to November.

Those months are mild and clear, 20°C to 27°C, with little rain. December and January are the coldest, dropping near 10°C with damp wind and fog, and many buildings have no heating.

May to September is hot, humid and wet, with August the wettest month. Hanoi still works then, at the lowest rates of the year, but plan indoor afternoons.

Hanoi is also the base for Halong Bay and Sapa, and both are at their best in the same months.

More about Best Time to Travel to Hanoi

Hanoi in Spring (February to April)

Temperature: 18°C to 24°C.
Weather: Mild and mostly clear after a cold January, with occasional drizzle. March and April are the best two months of the year.
Crowds: High, and Tet pushes rates up sharply.
Tip: The right months for walking the Old Quarter and Hoan Kiem Lake. Check Tet dates before booking, as much of the city closes for several days.

Hanoi in Summer and Monsoon (May to September)

Temperature: 28°C to 33°C, humid, with peaks near 40°C.
Weather: Hot and wet. Thunderstorms and long drizzles, with July and August the wettest months.
Crowds: Lowest of the year, with the cheapest rooms.
Tip: Do the Old Quarter early, then use the museums, cafes and cooking classes through the afternoon heat. Halong Bay cruises are sometimes cancelled by storms from July to September.

Hanoi in Autumn (October to November)

Temperature: 24°C to 27°C.
Weather: The clearest skies of the year with little rain. Along with spring, this is the pick.
Crowds: The busiest months in Hanoi, so book ahead.
Tip: The best window for day trips out of the city and for Halong Bay, and the most comfortable weather for street food and the lakes.

Hanoi in Winter (December to January)

Temperature: 10°C to 20°C, and it feels colder in the wind and damp.
Weather: Dry but grey and often foggy. Halong Bay gets misty enough to spoil the views.
Crowds: Moderate, with a bump over Christmas and New Year.
Tip: Pack a proper jacket. Many buildings have no heating, so this is colder than most travellers expect of Vietnam.
