Hanoi: the more comfortable choice for time outdoors

Hanoi is the coolest of the destinations here, with daytime temperatures averaging 29°C and nights at 22°C. That still calls for light clothing, but it offers a more comfortable starting point if strong heat tends to limit your plans. Its 11 rainy days also make it the least rain-prone option in this comparison, though you should still carry rain protection and leave room to rearrange outdoor activities. Plan more demanding outings for the cooler parts of the day rather than treating April as mild weather. For travellers balancing warmth with comfort, Hanoi is the strongest choice among these destinations.

Ho Chi Minh City: expect heat beyond midday

Ho Chi Minh City is the hottest option, averaging 34°C by day and 26°C at night. The catch is not just the daytime peak: evenings remain warm, so do not count on a cool night to reset after being outdoors. Loose, breathable clothes, regular water breaks and somewhere cool to rest are sensible priorities. Put more active plans earlier in the day and keep midday less demanding. With 12 rainy days, rain protection belongs alongside sun protection in your bag. This is a good fit if you enjoy hot weather, but Hanoi is a better match if heat quickly becomes tiring.

Phu Quoc: warm water, but more wet days

Phu Quoc makes sense if sea swimming is central to your holiday: both the daytime air and the sea average 30°C. The water is warm rather than a sharply cooling contrast to the air, while nights averaging 27°C offer little relief from the heat. The main trade-off is rain, with 19 rainy days making this the wettest option by frequency among the destinations compared. Keep your swimming plans flexible rather than relying on uninterrupted dry weather. A rainy-day figure does not tell you how long rain will last, so it should encourage backup plans rather than rule out time by the sea.
