Travel Guide to Visit Vietnam in Summer

Vietnam has two different kinds of climate, divided by the Hai Van Pass in Central Vietnam. While the North side of the pass has four separate seasons – which are cold in the winter and hot in the summer, the South side has only two seasons with warm temperatures all year round.

Climate differences between Northern and Southern Vietnam

Climate differences come from seasonal winds affected by the land’s shape. The Truong Son Mountain Range is the longest mountain range in Vietnam, running from Thanh Hoa to the Central Highlands. This range, especially the Hai Van Pass, blocks the cold Northwest wind from moving south. It also dries the Southwest wind from the Bay of Bengal, which leads to a dry season in southern Central Vietnam.

Moreover, Southern Vietnam is located close to the North of the equator, making this area’s climate hot and humid all year round. On the other hand, Northern Vietnam is located just South of the Tropic of Cancer, highly affected by the changes of solar angle throughout the year.

What is the best time for travelling to Vietnam?

Northern Vietnam is best visited from November to March. While autumn (September-October) and spring (January-March) offer pleasant temperatures (20-30°C), ideal for sightseeing and relaxation, the period from November to December is considered the best time to visit due to the cold, dry weather. Be prepared for occasional foggy days in the winter months. Summer (April-August) is hot and humid (30-35°C), but the mountains offer cooler temperatures compared to the delta.

Central Vietnam is best explored between February and August, when the weather is typically dry and calm with temperatures ranging from 25-35°C. From September to January, heavy rain is common. Enjoy activities like cooking classes, cycling, and boat trips. Soak up the history in Hoi An and Hue, or experience the vibrant atmosphere of Da Nang and Nha Trang.

Southern Vietnam enjoys consistently warm temperatures year-round, typically between 25-33°C. The dry season, from November to April, is ideal for experiencing local culture with its sunny, dry weather. While the wet season (May-October) does bring heavy rain, it’s an excellent time to explore the Mekong Delta and learn about the riverside communities.

What are the best tips for Vietnam in summer?

With its hot and humid weather, sightseeing experiences and recreational activities can be quite challenging for many travellers. Because of the heat, it’s best to plan the sightseeing tours and activities for the cooler parts of the day, like the morning and afternoon. This way, travellers can enjoy time outdoors without feeling too exhausted by the sun.

When preparing for a trip, remember to pack comfortable clothes that can help keep you cool and deal with sweat. Light fabrics that breathe are a great choice. Don’t forget to choose convenient shoes or sandals that you can wear for a long time. Comfortable footwear is important, as you may be on your feet a lot while exploring.

In addition to clothing and shoes, it’s very important to bring sunscreen and insect repellent. The sun can be very strong, so applying sunscreen can help protect your skin from harmful rays.
