The hurricane season in Vietnam starts in June and ends in late November and the first half of December.
On average, from January to May, storms are less likely to affect Vietnam.
From June to August, storms are more likely to affect the North. From September to November, storms are more likely to affect the Central and Southern regions.
Vietnam weather overview
Vietnam is a country stretching over a thousand miles, from Northern Sapa to the Southern Mekong Delta.
There are two relatively different climates: the Northern climate with 4 four seasons and Southern Vietnam with the tropical environment and only two seasons – the dry season and the rainy season.
The climate division between the two climatic zones is the Hai Van Pass between Hue and Da Nang.
Northern Vietnam Climate
A humid tropical monsoon climate characterizes northern Vietnam.
The annual average temperature gradually increases from the North to the South. Summer weather is from April to October, and it’s hot, humid, and rainy until the monsoon rises. Winter is from November to March, and the weather is cold, dry, and drizzle.
Also, the North has two interactions between the rainy season and the dry season, thus forming the spring and autumn.
The annual average temperature is about 25 degrees Celsius, and the average rainfall is 1,700 to 2,400mm.
In the winter, the temperature is the lowest in December and January. This time in the northern mountainous region such as Sapa, Tam Dao, and Hoang Lien Son, the temperature can be below 0 degrees Celsius, and it can appear frosty and may have snowfall.
Central Vietnam Climate
The central climate is divided into two main areas: North Central and South Central Coast.
The outstanding feature of the Central weather is that the rainy season and the dry season do not happen at the same time in the year of the two climatic regions of North and South.
North Central region (including the entire North of Hai Van Pass):
In summer, due to Lao wind, the temperature can reach over 40 degrees Celsius. Meanwhile, the air humidity is very low.
In winter, the whole area is affected by cold weather and rain because the monsoon blows in the Northeast, and it brings steam from the sea.
South Central Coast (including the South Central Coast area in the South of Hai Van Pass):
The northeast monsoon winds are often weakened by being blocked by the Bach Ma range.
Therefore, during the summer, the southwest monsoon winds which blow from the Gulf of Thailand and overflow the Truong Son mountain range cause hot and dry weather for the whole area.
Southern Vietnam Climate
The temperature does not change much in Southern Vietnam. It’s hot all year in the lowlands and cooler in the highlands.
The dry season is from December to April, with not much rain and a clear sky. The hottest months of the year are from March to May.
Public holiday in Vietnam
One crucial factor to consider the ideal travel time to Vietnam is the public holidays.
Vietnamese usually spend holidays traveling or visiting their families so that the service can be closed (especially during Lunar New Year – Tet Holiday).
It can be challenging to arrange transportation, such as bus or train during this time of the year, and the domestic and international flight tickets to and from Vietnam can be expensive.
Also, the price for hotels or other services can be double, which can be troublesome for those who love traveling on a budget.
Moreover, most tourist places are super crowded, and the roads to these places can have traffic jams.
In my opinion, you should avoid traveling during public holidays in Vietnam or plan well in advance before going.
The best time to visit Vietnam (by location)
The best time to visit Vietnam is from November to April, thanks to the dry season. However, the answer is not that simple because the climate in Vietnam is greatly affected by geographical conditions.
The best time to visit Sapa
Located at an average altitude of 1500 – 1600 meters above sea level, Sapa is a great place to avoid the hot temperature of Vietnam.
However, it is not always an appropriate time to travel to Sapa, and visitors are recommended to avoid visiting Sapa from June to August due to the rainy season.
March to May or September to November isthe best time to visit Sapa, and you can enjoy the beautiful rice paddy fields during this time of the year.
The best time to visit Hanoi
Hanoi is one of the most attractive tourist destinations in Vietnam.
Spring and Autumn are the best time to visit the capital of Vietnam. March to early April and from the end of August to October is considered the best time to travel to Hanoi. The weather at this time is quite pleasant and refreshing.
The former capital of Vietnam, Hue, is an excellent stop for those who love discovering history and culture. Hue is in the transition zone between the South and the North, so its weather reflects both regions.
Da Nang is one of the ideal vacation destinations for travelers with many beautiful landscapes such as Ngu Hanh Son, Ba Na Hills, Son Tra Peninsula, Hai Van Pass, poetic Han River, and My Khe beach.
The best time and the most favorable weather in Da Nang and most other coastal tourism provinces in Vietnam is during summer. In particular, April and May is the best time to visit Da Nang.
The best time to visit Hoi An
When is the ideal time to be able to feel and admire the full beauty of Hoi An old town that enchanted many people?
The climate in Hoi An is divided into two distinct seasons: the dry season and the rainy season. The rainy season starts from August to the end of December, and the dry season is from January to July each year.
Traveling to Dalat at the beginning of winter, you can experience feel the atmosphere and scenery changing day by day.
The best time to visit Ho Chi Minh city (Saigon)
May to November is the rainy season in Ho Chi Minh city, and these rains also come quickly and go very soon. It can rain in the morning, but in the afternoon, it’s sunny and changeable right away. Sometimes it rains all day long.
From December to April next year, Saigon is in the dry season. The outdoor temperature is very high, with the intense heat.
