Vietnam Weather and Travel Seasons: Where to Go and When

The best time to tour Vietnam overall is from November to April, when the weather is mostly dry and cool across all three regions. However, each destination shines in different seasons, so we’re here to help.

This comprehensive weather guide breaks down what to expect in Vietnam's most popular travel destinations by region - North, Central, and South - so you can pack right for your Vietnam tours and travel smart.

Northern Vietnam: Hanoi, Halong Bay, and Sapa

Climate Overview

Northern Vietnam goes through four clearly defined seasons: spring, summer, autumn, and winter. This region can get surprisingly cold in the winter and hot and humid in the summer.

Hanoi

The capital city, Hanoi, sees cool and dry winters from December to February and hot, humid summers from May to August. Spring (March-April) and autumn (October-November) offer the most pleasant weather, with mild temperatures and less rainfall, ideal for sightseeing around the Old Quarter, museums, and lakes.

- Best time to visit: March to April and October to November

- Avoid if possible: June to August (hot, humid, frequent downpours)

Halong Bay

Located along the northeastern coast, Halong Bay shares Hanoi’s climate but is more prone to mist and fog in the winter months. Summer (June-September) is the rainy season and brings the risk of tropical storms, which may affect Halong Bay cruises.

- Best time to visit: February to May and October to November

- Off-season note: December to January can be cool and foggy, with limited visibility.

Sapa

Situated in the northern highlands, Sapa enjoys a subtropical highland climate, meaning cooler temperatures year-round. Summers are warm and wet, while winters can be cold, sometimes even snowy.

- Best time to visit: March to May and September to November, when the rice terraces are lush and the skies are clearer.

- Avoid if possible: June to August (heavy rain and risk of landslides)

Central Vietnam: Da Nang, Hoi An, Hue, and Nha Trang

Climate Overview

Central Vietnam has a distinct dry and wet season, with the dry season from February to August and the wet season from September to January. This region is also most affected by typhoons.

Da Nang & Hoi An

These two coastal cities experience sunny and hot weather from February to August, making it ideal for beachgoers. From September to November, heavy rains and occasional typhoons can disrupt travel plans.

- Best time to visit: February to May (pleasant temperatures and clear skies)

- Avoid if possible: September to November (typhoon season)

Hue

Hue, the ancient imperial capital, receives more rainfall than Da Nang or Hoi An, especially during its extended wet season (September to January). However, the dry season (February to August) is perfect for exploring historical sites and tombs.

- Best time to visit: February to May

- Off-season tip: If visiting in late fall, pack waterproof gear and expect showers.

Nha Trang

Nha Trang’s weather is different from the rest of Central Vietnam. It has a long dry season from January to August, making it one of Vietnam’s best beach destinations. Rain peaks in October and November.

- Best time to visit: January to August

- Avoid if possible: October to November (short but intense rainy season)

Central Highlands: Da Lat

Climate Overview

Da Lat, located in the Central Highlands, offers a refreshing escape from the tropical heat. It has a cooler, temperate climate year-round and is known for its misty valleys, pine forests, and flower gardens.

The dry season runs from November to March, while the wet season spans from April to October. Even during the rainy months, showers often come in the afternoon and don’t last all day.

- Best time to visit: November to March for dry, cool weather

- Avoid if possible: June to August if you dislike frequent rain

Southern Vietnam: Ho Chi Minh City, Mekong Delta, and Phu Quoc

Climate Overview

Southern Vietnam has a tropical monsoon climate, with just two main seasons: dry (December to April) and wet (May to November). It remains warm or hot throughout the year.

Ho Chi Minh City (Saigon)

The city experiences high temperatures and humidity, especially during the rainy season (May to November). The dry season from December to April offers sunny days and clearer skies, perfect for exploring the city, its museums, and vibrant street food culture.

- Best time to visit: December to April

- Wet season tip: Rain often comes in short, heavy bursts, usually in the afternoon.

Mekong Delta

Like Saigon, the Mekong Delta is best visited during the dry season. The region’s rivers, floating markets, and lush rice paddies are easier to explore when there’s less flooding.

- Best time to visit: December to April

- Avoid if possible: September to November (flooding risk)

Phu Quoc Island

Phu Quoc has a classic tropical beach climate. The dry season from November to April is ideal for sunbathing, snorkeling, and island hopping. The wet season, particularly July to September, brings rough seas and heavy rains.

- Best time to visit: November to April

- Avoid if possible: July to September (monsoons, poor sea conditions)

Month-by-Month Snapshot

January - March: Excellent weather across most regions (dry and cool in the north; sunny in the south).

April - May: Warmer with more humidity; good for central beaches; end of dry season in the south.

June - August: Hot and rainy in the north and south; good for beach destinations like Nha Trang.

September - October: Rainy season in central and southern regions; good time for Sapa or northern Vietnam.

November - December: Best time for southern Vietnam and Phu Quoc; northern regions are cooler.

Tips for Travelers: Planning Around the Weather

Peak Season vs. Low Season

The dry/cooler/more temperate months generally correspond with higher tourist volumes. If you prefer fewer crowds and don’t mind occasional rain, consider visiting in shoulder seasons (just before or after the peak).

Pack for Variety

Because weather can change significantly, especially if you're traveling across regions, carry a light rain jacket, layers for cooler evenings (especially in the north or highlands), sun protection, and good walking shoes.

Typhoons & Storm Risk

North and Central Vietnam can be affected by tropical storms/typhoons especially between August and September. Always check weather alerts if visiting then.

Sea Conditions

If your itinerary includes islands, snorkeling, diving, or cruises (e.g., Halong Bay, Phu Quoc, Nha Trang), make sure to check sea/weather conditions. Rain, wind, or storms can disrupt or cancel boat activities.

Festival and Cultural Timing

Some months are more than just about weather; festivals (like Tet / Lunar New Year) and natural phenomena (flower blooms, rice harvests) can affect when you might want to travel. These often align with certain seasons.

Vietnam’s weather is as diverse as its landscapes and culture, and with the right planning, you can enjoy Vietnam’s beauty in any season. From cruising through Halong Bay to exploring the bustling streets of Ho Chi Minh City, there’s a perfect time to visit each destination, depending on your interests and climate preferences.
