Vietnam stretches over 1, 800km up the eastern coast of the Indochina peninsula and has various climates at the same time in different parts of the country.
Winter season lasts from November to April in the north with temperatures averaging 16 degree centigrade. The rest of the year is considered summer time with heavy rainfalls and occasional storms.
The rainy season lasts from May to October in the south. However, it only rarely rains the whole day long. It gets dry after rainfall as quickly as it comes. The dry season is generally from November to April.
The central parts of Vietnam are affected by the South West monsoon from Laos during May – June which causes a muggy heat and sometimes produces typhoons and tropical storms during November – December, with long lasting rains. Despite of this fact, the months of November and December are constantly considered the peak period of incoming tourists. January and February are still cloudy and rainy occasionally.
The best time for a long tour from North to South Vietnam would be from January till April and for those who wish beach holidays can come to enjoy warm water and sunshine in the central coast during summer time, from May to October.
