Vietnam stretches for almost 1,650km from north to south, creating striking differences in weather between regions.

While one part of the country may be cool and dry, another can be hot, humid or rainy. Choosing when to visit therefore depends largely on where you want to go and what you want to do.

When To Visit Vietnam

For a journey covering several regions, April to June and September to November can be especially rewarding. These shoulder-season months often bring fewer visitors and more manageable prices, although weather conditions can change from day to day.

For the best overall combination of regional weather, October to December suits northern Vietnam, March to May works well for central Vietnam, and December to February is ideal for the south.

Tet, the Vietnamese Lunar New Year, usually falls in late January or early February. During the holiday period, transport becomes extremely busy, accommodation prices rise and many businesses close, so advance planning is essential if your trip overlaps with the celebrations.

North Vietnam: October To April

Northern Vietnam is a strong choice for hiking and mountain scenery from October through April. Around Sapa, the rice terraces take on golden colours as the harvest approaches, while cooler temperatures make long walks more comfortable.

December and January can be surprisingly cold at higher elevations, and Sapa occasionally sees snow. Spring brings warmer conditions, while September to November is especially attractive for photographers looking to capture the region's famous terraces.

For Hanoi, December to March offers cooler, drier conditions that are comfortable for exploring the Old Quarter, museums, temples and street-food markets.

Central Vietnam: February To June

The central coast, including Da Nang and Nha Trang, is at its best from February to June, with increasingly warm and sunny conditions. February tends to be particularly pleasant before temperatures rise towards summer.

July and August bring large numbers of domestic travellers, especially during school holidays. Beaches and resorts become busier, while accommodation and flight prices can rise considerably. Booking ahead is recommended for popular coastal destinations.

For Hue and Hoi An, January to March offers pleasant conditions for exploring historic buildings, temples and atmospheric old streets.

Halong Bay And Sapa

October and November are excellent months for a trip to Halong Bay and the quieter Bai Tu Long Bay. Temperatures are mild and there are generally more dry days than during the summer storm season, making this a good period for boat trips and outdoor sightseeing.

Sapa has its own rhythm. September to November brings golden rice terraces and cool hiking weather, while April and May offer mild temperatures, flowers and clear mountain views. Summer turns the terraces vivid green, though frequent rain can make trails slippery and muddy.

South Vietnam And Phu Quoc

Southern Vietnam is generally most comfortable from December to April, when Ho Chi Minh City and the Mekong Delta experience drier conditions. These months are well suited to walking tours, river excursions and exploring the city's historic districts.

Phu Quoc has a particularly simple seasonal pattern. November to April brings the island's dry, sunny season, making it the best period for beaches, snorkelling and exploring inland areas. It is also the busiest and most expensive period for accommodation and transport. From May to October, heavier rain becomes more common.

When To Avoid Vietnam

The main weather-related concern is the typhoon season. Vietnam can experience tropical storms from May to November, with August and September carrying the greatest risk. Storms can disrupt flights, boat trips and coastal travel, particularly around the northern and southern coasts. Heavy rainfall can also cause flooding and transport problems.

How Much To Budget

Vietnam remains one of Asia's most affordable destinations. A budget traveller can expect to spend roughly €36–€63 per day, including basic accommodation, food and local transport. Hostel dorms start at around €4–€9, while a basic double room can cost about €9–€18. A local bus journey can start at less than €1, and street-food staples such as banh mi can cost around €0.60.

For the best balance of weather, prices and crowds, consider travelling during the shoulder seasons and build your itinerary around one or two regions. With two weeks, you can cover several of Vietnam's major highlights; shorter trips work better when focused on a single area.
