Hanoi has a humid subtropical climate with two distinct seasons: a hot, wet monsoon from May to September and a cooler, drier period from October to April. The live forecast above shows current conditions, but for planning a trip, the best months are typically October through December and March through April.
When is the best time to visit Hanoi?
The most comfortable weather for sightseeing runs from October to April, when humidity drops and daytime temperatures sit between 20°C and 27°C. January and February can be chilly (15–20°C), so pack a light jacket. The monsoon months from May to September bring heavy downpours and high humidity, though the city is still worth a visit if you don’t mind the rain. For a detailed breakdown, check the 10-day forecast before you go.
What should I pack for Hanoi?
For the dry season (October–April), bring layers: long-sleeved tops, a medium-weight jacket, and comfortable walking shoes. In the wet season (May–September), pack a waterproof jacket, quick-dry clothing, and an umbrella. Lightweight cotton clothing works well in the heat, but note that air conditioning is common indoors, so a light scarf or cardigan can be useful. The UK weather hub can help you compare conditions if you’re travelling from Britain.

The rainy season runs from May to September, with peak rainfall in July and August. During these months, heavy but often brief showers are common, and the city can experience occasional typhoons.
