Vietnam’s climate is dominated by a tropical monsoon system, but the country’s 1,650km length creates stark differences: the north has four distinct seasons while the south stays warm and humid all year. The central coast sees the heaviest rainfall during autumn.

What are the key climate zones of Vietnam?

North Vietnam (Hanoi, Ha Long) experiences a humid subtropical climate, with cool winters (15–20°C) and hot, humid summers (30–35°C). South Vietnam (Ho Chi Minh City, Mekong Delta) is fully tropical, with a wet season (May–November) and a dry season (December–April). Central Vietnam (Da Nang, Hoi An) is transitional, with high rainfall from September to December.

When does the monsoon season disrupt travel?

The worst time to visit Vietnam depends on the region. In the north, heavy rain and typhoons arrive between July and September. The south’s monsoon peaks from June to August, bringing daily downpours. The central coast is most affected from September to November, when flooding can isolate towns. For up-to-date conditions, check a 10-day forecast before planning travel. The Vietnam climate today can shift quickly, especially along the coast.

What is the climate of North Vietnam compared to the south?

North Vietnam has four seasons including a cool winter, while the south has only two: wet and dry. The Vietnam climate map clearly shows this divide at the Hai Van Pass. Temperatures in the north can drop to 10°C; the south rarely dips below 24°C.

What is the worst time to visit Vietnam for weather?

The worst time to visit Vietnam is during the central monsoon (September–November) when typhoons and flooding are common. The north’s peak rain season (July–September) also disrupts outdoor activity. Check the weather in Vietnam 10 days ahead for regional alerts.

Does Vietnam have a dry season?

Yes, the south has a distinct dry season from December to April, with clear skies and lower humidity. In the north, the dry period is November–April, though winter can bring drizzle. For a detailed overview, see our UK weather hub for comparative climate patterns.
