Weather in Hanoi

Hanoi is the capital city of Vietnam, located in the center of the northern region. Nowadays, many foreigners decide to live long-term in Hanoi, not only because it’s a beautiful city, but also because the cost of living here is cheap. In this article, I will share some basic notes about Hanoi. Let’s start with the weather and climate. 

The Hanoi climate is typical of northern Vietnam. Expect a humid tropical monsoon climate with the very hot and rainy summers and cold dry winters. From May to September is summer, also known as the rainy season. Winter lasts from November to March. Between these two main seasons, spring and autumn act as pleasant transitions in April and October respectively.

During the summer, the estimated average temperature is 28 degrees Celsius. The hottest season is in June, of which the monthly average temperature is 29.2 degrees Celsius, some days it gets up to 38 degrees. You will feel extremely irritated by this kind of weather! But this heat does not last long because after the hot consecutive days, it will rain heavily, dampening all the heat in Hanoi.

From mid-September, it turns steadily into autumn when the temperature drops and rain lasts for several days. In autumn, the plants change from green to yellow. People say that autumn is the most stunning and charming season in Hanoi, in which Hanoi becomes subtle and poetic. There have been many songs and poems written about Hanoi’s fall season.

In November, winter arrives. Dry air blows from the northeast to Vietnam, bringing with it low temperatures and a very dry atmosphere. Temperatures can be as low as 17 degrees Celsius. This season feels colder than usual because the humid air makes for a chilling atmosphere. The cold humidity gets into your clothes and can leave you more chilled than expected.

In February and March, the temperature and humidity rise. It begins to rain all day long. This is the signal of spring. Usually, Tet (Vietnamese New Year) occurs during spring, when plants start to revive. From April to May, the first thunder indicates the arrival of summer. Then, the cycle of the seasons continues.
