In general, there’s no ‘best’ time for travelling in Vietnam as the seasons are a little vague and vary considerably from north to south, and within regions. In the south, the dry season generally runs from December to June with March to May being particularly hot and humid. Temperatures usually range from 27°C to 36°C during this time. The wet season brings short and heavy rain showers from July to November, with temperatures averaging between 22°C and 27°C.
Unlike the South, the northern regions of Vietnam have four seasons. Winter is from December to February – it can be extremely cold in Hanoi and the mountainous regions, with overnight temperatures of 4°C and daytime highs between 10°C and 20°C. Summer is June to August – expect hot and humid conditions at this time, with temperatures averaging between 27°C to 30°C and high humidity.
