The climate of Vietnam
The Socialist Republic of Vietnam or Vietnam for short is a country located in the southeastern part of the Asian continent. The elongated country has a coastal area in the east along the South China Sea (on the Gulf of Tonkin), in the north Vietnam borders China and in the wets it borders the countries of Laos and Cambodia. With a population of almost 100 million Vietnam is among the countries with the highest population figure in the world. Most people live in the lower regions in Vietnam. In the northern part of the country a low plain can be found around the Red River Delta. In the southern part a large plain is situated at the mouth of the Mekong River. During the monsoon the Mekong Delta often floods caused by heavy rainfall in Laos, Cambodia and Vietnam itself.

Climate types
The largest part of Vietnam has a tropical savannah climate (type Aw according to the Köppen Geiger climate classification). The lower regions have a tropical monsoon climate (type Am) and the most northern part has a warm China climate. In the southern part of the country the southwesterly monsoon causes high precipitation figures from May till November. During some months locally 400 millimeters of precipitation can be recorded (long term average). During longer periods with precipitation heavy rainfall may cause the Mekong River to flood. The coastal area east of the Annamese mountain range is influenced by a northeasterly monsoon that causes high precipitation figures in October and November.

In the southern part of Vietnam temperatures are quite stable. Daytime temperatures are between 30-36 degrees Celsius (86-96 degrees Fahrenheit) all year round. During the night temperatures hardly ever drop below 20 degrees Celsius (68 degrees Fahrenheit). The northern part of the country, where the capital Hanoi is located, has a climate with distinct differences in temperatures. During the summer temperatures reach tropical figures. During the winter daytime temperatures are only 20-24 degrees Celsius (68-75 degrees Fahrenheit). Minimum temperatures are 10-17 degrees lower here than in the southern part of the country. In the high mountain regions, both in the south around Mount Da Lat and in the north in the vicinity of the border with China temperatures may drop to freezing point or even lower during the winter.

From May till December there is a risk of hurricanes in Vietnam. The largest risk of a tropical storm that may develop into a hurricane is from July till October. Because the country is situated on the South China Sea Vietnam is vulnerable to tropical storms. Unfortunately, Vietnam regularly makes the headlines because of damage and or casualties caused by a tropical storm or hurricane.

More climate information
Climate tables are useful but they don’t give an overall picture of the climate and possible weather conditions during a period of time. How high the chances are of hot or cold weather or hurricanes can often not be found in these tables. This is why we offer extra climate information per month. The figures below are for the capital Hanoi. For climate figures on specific regions and places please, visit the individual climate pages of Vietnam
