With over 2000km of coastline running the length of the country and a mountainous northern interior, the weather in Vietnam can differ vastly depending on where you go and this affects the best time to go. In Hanoi and the north, the dry season runs from November to April, with wetter, more humid conditions from May to October. In the far north around Sapa, the dry season lasts from October to late March with September to November and March to May the best time to trek. Central Vietnam experiences a dry, hot season from January to August, while the south of the country is best visited between November until early May. If you want to take in both the north and south of Vietnam, February and March are the best months to do this.
If you are looking to cover a lot of Vietnam in one trip, head over around February/March to catch both north and south at their best. This time of year is most likely to ensure the best weather across the whole country.

Vietnam gets very busy around Chinese New Year and we suggest avoiding this time of year if you can. The Hoi An Lantern Festival is really lovely and takes place each month, although the exact date varies. The town is lit up with colourful lanterns with houses and shops arranging beautiful displays. There are usually activities going on along the Thu Bon River as well.
“From start to finish, Jacada curated an unparalleled experience in Vietnam and Cambodia. Though we enjoyed the absolute in luxury for accommodations, the highlights of our journey had to do with the local guides and the off the beaten track experiences. Of course, transfers were flawlessly executed and we never had to concern ourselves with any of the minute details. Shout out to Rachel who put everything together for us. We’re already looking forward to our next adventure.”
