May is the start of the rainy season in Vietnam. However, it's still a long way off and you can choose days and places where your vacation will be just fine. For example, in the Central Provinces in May, the dry weather is just getting fully established. Therefore, Hue and Danang will meet you not only a great beach vacation (by the way, the beaches in May will be half-empty), but also the opportunity to spend a great time on sightseeing in these amazing cities. Temperatures are a comfortable +27°C.
Temperatures remain at +33°C in the cities of South Vietnam. But with frequent rainfall, the humidity starts to rise and the heat can be hard to bear. So you should think twice before choosing resorts near Ho Chi Minh City and other southern cities.
When you vacation in Vietnam in the spring in the Northern provinces, you'll finally find warmth at +25°C. The rains are starting to pick up, but that won't stop you from swimming in Halong Bay or touring Vietnam's capital.
On a tour to Vietnam in May, you are almost guaranteed to be at one of the local festivals. On the first days of May, there are Labor Day parades, and on the 19th, Vietnam celebrates the birthday of its first president, Ho Chi Minh. Whale Worship Festivals are held at various times in the maritime provinces, and one of Ho Chi Minh City's parks hosts a Fruit Festival.
