Vietnam stretches over 1,600 kilometres north to south, so the weather is rarely the same everywhere. The North has a real winter, cool and sometimes misty from December to February, and a hot, humid summer.
The Centre runs on an opposite calendar: sunny from February to August, with most of its rain between October and December. The tropical South alternates a dry season from November to April with a rainy season of short downpours.
The good news: there is always an ideal route. March–April and October–November let you travel the whole country in excellent conditions.
