Geography and climate
With the total area of approximately 331,688 km2, the territory of Vietnam consists of hills and densely forested mountains. Vietnam is bordered by China to the north, Laos and Cambodia to the Southwest. The rest of the country is surrounded by the Gulf of Tonkin, the South China Sea and the Gulf of Thailand.
Shaped like an elongated S, Vietnam stretches the length of the Indochinese Peninsula. Topographically, Vietnam is a verdant tapestry of soaring mountains, fertile deltas, primeval forests inhabited by exotic fauna, sinuous rivers, mysterious caves, otherworldly rock formations, and heavenly waterfalls and beaches. Beyond nature, the curious and open-minded visitor will find in Vietnam a feast of culture and history.
In general, the climate is different from the north, the middle and the south of Vietnam. In the northern of Vietnam, there are four seasons: spring, summer, autumn, and winter, however, in the southern of Vietnam, there are two seasons including dry season and rainy one.
It is thus preferable to travel to North Vietnam during the month of November or from late April to early May when temperatures are still cool (between 15 and 25 degrees). Conversely, it is not advisable to visit northern Vietnam in July or August as temperatures can soar to 40 degrees in the shade.
In the center, the best period is between February and May, while the period is not recommended in September: typhoons may form off and come to the coast.
Southern Vietnam experiences very little seasonal temperature change. It has a tropical, hot and humid, climate, and has only two real seasons - the monsoon season and the dry season.
It is advisable to bring light clothing, easily washable and dries quickly, to travel to Vietnam: Shorts, skirts, t-shirts, tank tops, hat, rain coat. Bring warm clothing for the cooler evenings, especially if you travel to North Vietnam or during the winter where temperatures can be very cold. If you forget, do not worry, you will find in Vietnam all kinds of cheap clothes.
Generally, there is really no bad time to visit Vietnam. Everything ultimately depends on your preferences to travel with cooler or warmer weather.
