Where to go: Hanoi has the clearest advantage

Hanoi is the strongest July choice among these destinations if fewer rainy days are your priority. It has 21 rainy days, compared with 29 in Ho Chi Minh City and 28 in Phu Quoc. The catch is heat: Hanoi reaches 32°C by day and stays at 26°C at night, so do not expect much cooling after dark. Ho Chi Minh City is slightly less hot during the day at 31°C, with nights averaging 24°C, but rain is a more frequent consideration. Phu Quoc has the lowest daytime average at 28°C. Choose it for less intense daytime heat rather than for dry weather, and keep outdoor plans flexible whichever destination you pick.

What the weather means for your holiday

Pack light clothing, practical rain protection and footwear you can comfortably wear in wet weather. With countrywide sunshine averaging 1.8 h, July is better suited to travellers who can enjoy a trip without long sunny spells than those planning to spend most days sunbathing. Keep your schedule flexible rather than making every day depend on outdoor activities, and leave room for breaks from the midday heat. The sea averages 29°C, including around Phu Quoc, so cold water is not the main concern for a swim. Rain and conditions on the day still matter, however: warm sea temperatures alone do not make July a reliable beach month.
