Best Time To Visit Hanoi

As Vietnam’s capital, Hanoi is home to an abundance of landmarks and must-see sights, from temples and lakes to night markets. Hanoi’s famed Old and French quarters make up just part of this incredibly vibrant city. With a turbulent history (still very much on display), there remains much to discover in what used to be the beating heart of French Indochina. And whilst travelling, it’s noteworthy to think about Hanoi weather to find out the best time you can visit this beautiful capital city.

When to visit Hanoi

Depending on your origin, you may find that you would be comfortable visiting Hanoi at any time of year. However, with an average temperature difference of +10°C between some months, it’s worth thinking about your preferred temperature for exploring this ancient city.

How much time to spend in Hanoi

In order to fully appreciate the sights of Hanoi, allow two or three days to visit the city. Ho Tay (the West Lake) deserves an afternoon or morning to itself, whereas the delights of the Old Quarter are best enjoyed in the evening. Stay for a couple of days and join in with the local routine of t’ai chi practice at dawn and dancing in the public squares (particularly Thong Nhat Park) at night.


Taking everything into account, March – April and September – November are the best times to visit Hanoi. During these months the temperature is neither cold enough to require several layers of clothing nor so hot that walking around outside becomes a chore. The months of October and November have the least rainy days, whereas March and April see comfortable temperatures averaging around 22°C.
