Despite the complex weather patterns, May is still a great time to visit Vietnam. As a transitional month between spring and summer, the country experiences increased rainfall and rising temperatures. In Hanoi and northern Vietnam, the heat and humidity start to build, accompanied by more frequent showers—yet the weather remains comfortable enough for outdoor activities. Along the central coast, hot and sunny days make it one of the best regions to explore during this time. Meanwhile, southern Vietnam begins its gradual shift into the rainy season. Let’s take a closer look at the weather and top destinations to visit in Vietnam during May.

May in northern Vietnam marks a pleasant shift into summer, with temperatures typically ranging from 24 to 36 degrees Celsius. It’s an excellent time to visit both the northern and central regions of the country. However, travelers should be prepared for occasional weather disruptions, including storms or tropical depressions that may lead to changes in plans, such as canceled boat tours in Ha Long Bay. The mountainous areas like Mu Cang Chai and Sapa enjoy comfortable weather during this period, as local hill tribes begin planting rice on the terraced fields. In contrast, Ha Giang, located further east, tends to experience heavier rainfall. Despite this, May remains a wonderful time to explore Ha Long Bay, a UNESCO World Heritage Site.

1.2 Central Vietnam

Popular destinations: Hoian, Danang, Hue, Nha Trang, Quy Nhon, Dalat, etc.

In May, South Vietnam begins its transition into the rainy season, though the change is gradual and mild. Here’s what you can expect:

• Temperature: Expect hot and humid days with highs ranging from 28 to 36 degrees Celsius (82 to 97 degrees Fahrenheit).

Overall, May remains a great time to visit South Vietnam. The occasional rain showers offer a refreshing break from the heat and are unlikely to cause major disruptions to your travel plans.

2. Places to go in Vietnam in May & Useful Tips.

With average temperatures ranging from 20 to 30°C, the Mu Cang Chai and Sapa regions remain mostly dry, making them ideal for trekking. In particular, the terraced rice fields of northern Vietnam are at their most stunning during this time. May marks the “falling water season,” when fresh water cascades from one terrace to the next, and the fields shimmer with vibrant green and golden hues from the new rice crop.

Best known for its vibrant “butterfly season” in April and May, Cuc Phuong National Park is an ideal destination for wildlife enthusiasts and adventure-seeking travelers.

Protected by the Truong Son mountain range, Central Vietnam experiences significantly less rainfall in May compared to other regions of the country. It’s an excellent time to visit its beautiful beaches, such as the pristine white sands of Nha Trang, the calm, warm waters of Quy Nhon, or the more secluded Lang Co Bay. Additionally, combining beach time with cultural exploration in Hue and Hoi An—both UNESCO World Heritage Sites—would make for an unforgettable experience.

The South is known for its hot, humid weather and frequent rainfall, but it enjoys slightly cooler temperatures compared to previous months. Therefore, visiting Ho Chi Minh City’s main attractions and air-conditioned museums remains a great option.

The island in South – Con Dao is still in favorable diving conditions during this month. Don’t miss it.

As the hot, rainy season approaches, with increased rainfall across the country throughout the month, it’s essential to pack rain gear, insect repellent, and summer clothing. Don’t forget to bring a sunhat, sunglasses, or a parasol to shield yourself from UV rays. If you’re heading to mountainous regions or the Central Highlands, make sure to include a couple of warm layers for the cooler early mornings and late nights.

At the start of the month, during the April 30-May 2 holiday, city dwellers often head out of town for a quick getaway, making it a busy time, particularly at the beaches. However, later in the month, you can still enjoy the best beaches under glorious sunshine, but without the earlier crowds. Another advantage of May is that tour prices and accommodation rates tend to drop, or are more negotiable, making it an ideal time to visit.
