The weather in June is simply hot. In Hanoi, the air quality becomes worse with overheated weather in combination with the volume of traffic and sometimes the dust. In some central provinces and cities like Hue and Hoi An, the heat is very much higher and hit its peak temperature due to the intense amount of sunlight. Ho Chi Minh City and southern provinces can be expected with hot weather and frequent downpours. Mountainous areas and Central Highlands are exceptional when the advantages of topography bring back a milder weather, the rains are also more frequent and spreading all the regions. Trekking is not a good recommendation when traveling in Vietnam during this time.
Because of the variety from north to south, there are always suitable destinations for you to escape from the summer heat like Sapa, Tam Dao, Dalat, where the weather is relatively cool and pleasant.
