The weather in Vietnam is quite varied, so it’s important to consider the best time to travel to Hanoi. Unlike Australia, the city experiences summer in June and winter in December.
As Hanoi is in the northern part of Vietnam, it experiences the humidity, heat, and typical yearly patterns of a tropical country. During monsoon season, heavy downpours arrive in the afternoon but leave after a few hours.
The winter months also have a chill in the air. If you visit Ha Long Bay on a day trip, you'll find it's often covered in mist, giving it a more ethereal appearance.
