Where to go in June
Hanoi is the strongest choice here if avoiding rain matters more than avoiding heat: it has 18 rainy days, compared with 28 in Ho Chi Minh City and 27 in Phu Quoc. The catch is its daytime average of 33°C, which makes a packed outdoor schedule less appealing. Ho Chi Minh City is slightly cooler at 31°C, but suits travellers willing to switch between outdoor plans and indoor breaks when rain arrives. Phu Quoc has the lowest daytime average at 29°C, so it may appeal if you dislike stronger heat. However, its frequent wet days make it a poor choice if your main aim is a reliably sunny beach holiday. Choose for your tolerance of heat and rain, rather than expecting dry conditions.
Expect warm evenings and limited sunshine
Plan for warmth that continues after sunset, rather than relying on evenings to feel cool. Night-time averages are 26°C in Hanoi and Phu Quoc, and 25°C in Ho Chi Minh City, so light clothing is more useful than heavy layers. Carry lightweight rain protection and keep outdoor plans easy to rearrange. With country-average sunshine of 1.7 hours a day, do not build the trip around long sunny spells. The sea averages 30°C nationally and around Phu Quoc, making water temperature less of a concern than the weather on the day. Leave room for shaded or indoor breaks around midday, especially in Hanoi.
