June is still a good month to travel in Vietnam despite it being a slightly mixed bag in terms of weather. The centre of Vietnam has now hit peak temperatures and remains dry and bright. The south is now in the midst of the wet season with daily downpours to be expected, usually in the afternoon, whilst the north is well into summer mode with high temperatures and rain being the norm. Visitor numbers relatively low and the central beaches still promise a great deal of sunshine. Trekking is off the cards for most, with more rain spreading through the northern mountains & central highlands.
The north of the country is firmly in the middle of its summer by June meaning you can expect plenty of hot weather as well as rain and at times storms (avg temp: 30 °C). The mountains to the north are also very wet with extensive trekking unadvisable throughout the month.
Dry, sunny days and blue skies continue for central Vietnam in June. The beaches of Hoi An, Danang and Nha Trang are at their best (avg temp: 30 °C); further north Hue is also enjoying good weather. In the Central Highlands and Dalat to the west, rainfall is still on the increase although travel is still possible.
The south is now firmly into its wet season. However this is unlikely to be severe, and whilst the showers will be slightly heavier than in previous months you can still expect plenty of dry and bright daylight hours (avg temp: 28°C). June marks the start of Green Turtle nesting season on the beaches of Con Dao.
