The climate in Vietnam is varied, that means the best time to travel to the country in terms of the weather will depend on where precisely you want to go and what you want to do. Broadly speaking, Vietnam has 3 regions: North, Central and South and climate in each region is different. The winter monsoon that runs from October to March typically makes the north of the country cool and damp, while the south is dry and warm. From April or May to October, the summer monsoon generally leads to the whole nation becoming quite humid and hot – except for around the mountains.
Travelers can visit Vietnam any time of the year, with no notable “off-season”. The best places for beach going tends to vary throughout the year based on what the weather is doing. The wet season typically spans from May to September, though visitors are still able to visit most areas. In the northern regions average temperatures range from 17-22 C (62-71 F) during the cool and dry winter time from November through April, and can get as low as 10 C in the far north mountainous regions. Temperatures range from 25 to 35 C (77 – 95 F) in the south year-round and only sees slight variation between dry season and wet season (which runs from May to November).
