Vietnam is a lovely country in Southeast Asia. With the beautiful landscape and cultural values, Vietnam is attractive to a great number of tourists around the world. If you want to travel to Vietnam, it is necessary to learn more about the weather in Vietnam so that you can arrange a good itinerary for your Vietnam journey.
Basic characteristics of weather in Vietnam
Vietnam lies entirely within the tropical belt of the Northern Hemisphere and inclines toward tropics rather than the equator.
That geographical position brings Vietnam high temperature. The average annual temperature is from 22ºC to 27ºC. Every year, there are about 100 rainy days with average rainfall of 1,500 to 2,000 mm. The humidity is less than 80%. The number of hours of sunshine ranges from 1,500 to 2,000 and the average radiant heat is 100kcal / cm².
Monsoon also contributes to the change in the humid tropics of Vietnam. In general, Vietnam has a hot season with much rain and a relatively cold season accompanied by a small amount of rain.
Vietnam is strongly affected by the northeast monsoon; therefore, the average temperature in Vietnam is lower than the that of many other countries that have the same latitude in Asia. Compared with these countries, Vietnam has colder weather in winter and hotter weather in summer.
Difference between the climate of North Vietnam and South Vietnam
Vietnam has a tropical monsoon climate and the weather is different from region to region.
Although Vietnam’s territory lies in the tropics, the climate in Vietnam is divided into separate climatic zones.
The distinct climatic differences are the climate features of the North and the South bordered by Hai Van Pass.
Climate is defined by several elements including temperature, humidity, precipitation, atmospheric pressure, wind, atmospheric phenomena and other meteorological factors over a long period of time in a certain region. “Climate” is quite different from “weather” in terms of time because the weather just refers to current or upcoming occurrences.
The climate of an area is influenced by geographic coordinates, terrain, elevation and stability of snow cover. The climate is divided into different types based on the exact parameters of temperature and precipitation.
Therefore, distinctive climatic characteristics are one of the reasons for that fact that the North is in a cold climate while the South is still warm.
The difference is that the North has a humid subtropical climate with four seasons: spring, summer, autumn and winter and the South owns a tropical savanna climate.
The subtropical humid climate is a typical type of climate characterized by hot and humid summer and cold winter.
With tropical savanna climate, the average temperature of every month throughout the year is over 18 ° C and there is a distinct dry season.
The geographical location is also a determinant of the climate difference between the North and the South. The northernmost point lies near the tropics (23°22′N) and the southernmost point is not far from the equator (08°35’N). Because the North belongs to higher latitude than the South, it is enormously influenced by the Northeast monsoon while the Northeast winds gradually weaken when going into the South.
In addition, Vietnam is located in the Northern hemisphere, in the Tropic of Cancer and the South is close to the Equator. As a result, this region receives a large amount of radiation every year.
