Hanoi’s subtropical climate delivers distinct seasons, from a cool, damp winter (November to March) to a hot, humid summer (May to September). The best time to visit is spring (April) or autumn (October to November), when temperatures are mild and rainfall is low.

Vietnam weather year round: how Hanoi compares to the rest of the country

Vietnam weather varies significantly between the north, centre, and south. Hanoi, in the north, has a true winter, whereas Ho Chi Minh City remains warm all year. Central Vietnam, including Da Nang, experiences a wet season that peaks sharply between September and November, coinciding with the best weather in Hanoi. Understanding vietnam weather by month is essential for multi-destination trips, as you may need both a jacket and shorts in the same week.

Hanoi weather by month: seasons explained

Vietnam weather in Hanoi is defined by the northeast monsoon, which brings cool, dry air in winter and warm, humid air in summer.

Winter: November to January (cool and dry)

Vietnam weather in November remains pleasant, with low humidity and high temperatures around 25°C. By December and January, daytime highs drop to 19–22°C, and nights can fall to 14°C. This is the best time for walking tours, but a jacket is essential. Vietnam weather in December often brings overcast skies and light drizzle.

Spring: February to April (warming up)

February and March are typically grey and drizzly. Weather in Vietnam in April marks a clear shift: temperatures rise to 30°C, humidity increases, and sunshine becomes more reliable. It is an excellent month for sightseeing before the heavy rains begin.

Summer: May to September (hot and wet)

Summer is hot, humid, and rainy. Weather in Vietnam in September still carries this heat and humidity, though the worst of the monsoon often eases by the end of the month. Typhoons are a risk in July, August, and September, so monitoring the UK weather hub for updates on regional storms is advisable if you are travelling during these months.

What to pack for Hanoi’s climate

Packing depends entirely on the season. For winter (November to January), bring a warm jacket, jumpers, and long trousers. The cold is damp and can be more penetrating than the temperature suggests. For summer (May to September), pack light cotton clothing, a waterproof jacket, and mosquito repellent. For the transitional months of April and October, layering is key: t-shirts for the day and a light jacket for the evening. Those used to the climate of southern Europe, such as Barcelona weather, will find Hanoi’s summer humidity more intense.
