Plan your trip around the dry season (November to April) for the most reliable sunshine, especially if you’re heading to central or southern Vietnam. The north has a distinct winter, so pack layers for Hanoi if travelling between December and February.
What is the climate like across Vietnam?
Vietnam’s climate varies dramatically from north to south due to its 1,650km length. The north (Hanoi, Ha Long Bay) has a humid subtropical climate with a cool, dry winter (November–April) and a hot, wet summer (May–October). Central Vietnam (Da Nang, Hoi An) experiences a dry season from January to August, with heavy rain peaking between September and November. The south (Ho Chi Minh City, Mekong Delta) is tropical, with a dry season (November–April) and a rainy season (May–October) where downpours are heavy but brief.
What should I pack for Vietnam?
Lightweight, breathable clothing works year-round in the south, but pack a rain jacket or umbrella for the May–October wet season. In the north, bring a warm layer for winter evenings (temperatures can fall to 10°C). Sturdy sandals and a sun hat are essential for sightseeing. If you’re heading to the highlands (Sapa, Dalat), a fleece or jumper is needed year-round.
What is the worst time to visit Vietnam?
The worst time is often September to November in central Vietnam, when typhoons and heavy rain can disrupt travel. The north’s summer (June–August) brings high humidity and frequent downpours, though it remains popular.
