Mountainous Far North
Sapa, Ha Giang, Bac Ha, Mu Cang Chai
The climate in Sapa and Vietnam’s north-west region including Mu Cang Chai is divided into two seasons: the dry season runs from October to late March with the wet season lasting from April to September. It can get very cold and frosty in December and January, especially at night.
The best months to travel in the north-east (Ha Giang) is during the dry season, from October to April, although December and January can get very cold. We recommend avoiding travelling in Ha Giang during the rainy season (May to September).
Trekking and adventure:
The best trekking conditions in Sapa and around Mu Cang Chai can be experienced between September & November, and from March to May. Daytime temperatures range from 15-28°C, and night-time temperatures from 10-18°C. Trekking and cycling are possible year round, however the winter time can be rather chilly, and the summer rather wet.
Hoi An, Danang, Hue, Dalat, Quy Nhon & Nha Trang
Hoi An, Hue & Danang in the centre of Vietnam have hot and dry weather from mid-January to late August, with temperatures often reaching the mid-30's °C. During the winter months the rainfall increases with October and November achieving peak levels, occasionally in the form of typhoons.
Hue is often cooler than Hoi An, especially early in the year. In addition, with each sitting on opposite sides of a small mountain range the weather can often differ between the two greatly on any given day.
Quy Nhon is a six hour drive south of Hoi An and shares a similar weather pattern although the dry season is slightly longer due to its proximity to the southern system.
At the far south of Central Vietnam, Nha Trang benefits from a longer dry season (typically January to September), with high temperatures and little rain . The rainy season runs from October to early December with almost half the annual rainfall falling in October and November.
Dalat, in the central highlands, is wet from June to October making outdoor pursuits problematic. From November to May it is far drier although cold in December & January.
