When is the best time to visit?
The best time to fly to Vietnam depends on your priorities for weather and cost.The cheapest flights to Vietnam are available during the off-peak months of May to September, which coincide with the rainy season. If it's sunshine you're after, make your Vietnam holiday somewhere between November to April, when it's hot, dry and ideal for outdoor activities, from hiking to sunbathing. This is the busiest season, though, so book your flights and hotel as far in advance as you can to avoid higher prices.
There's also slight variations in weather by region:
North Vietnam (Hanoi, Sapa, Halong Bay): October to April offers cooler, drier weather.
Central Vietnam (Hoi An, Da Nang, Hue): February to May provides warm, pleasant conditions.
South Vietnam (Ho Chi Minh City, Mekong Delta): November to March is dry and comfortable.
