Best Time to Visit Hanoi

The most comfortable months to explore Hanoi are from April to June and September to early December. In spring (April–June), you’ll enjoy vibrant street life under blue skies, though it can get quite hot. Autumn (September–November) is arguably the most beautiful time, with cooler air, clear sunlight, and perfect weather for walking tours around the Old Quarter, Hoan Kiem Lake, and West Lake.

If you're visiting in June through August, prepare for intense heat and frequent showers. Bring breathable clothing, sunscreen, and an umbrella. For those arriving in winter (late December to March), Hanoi may surprise you with its damp chill, so pack layers and a warm jacket. The city's misty atmosphere during this season adds a poetic charm, especially around Tet (Lunar New Year).

Weather in Halong Bay

Halong Bay, located in Northern Vietnam, experiences four distinct seasons. Its weather can shift dramatically throughout the year, shaping the kind of experience you’ll have on the water.

Seasonal Overview:

Best Time to Visit Halong Bay

The best time to explore Halong Bay is between April and June or September to November. These months offer the most favorable conditions for sailing, kayaking, and soaking in the iconic limestone karsts under clear skies.

Traveling in the off-season, particularly in winter (December to March), has its own charm. Heavy mist and colder temperatures can cast a mystical ambiance over the bay, turning the scenery into a surreal seascape. Just remember to pack extra layers, especially if visiting in January, when it can feel quite chilly.

Weather in Sapa

Nestled in the Hoang Lien Son Mountains near the Chinese border, Sapa is known for its dramatic landscapes, ethnic hill tribes, and distinctly cooler climate. At over 1,500 meters above sea level, this northern highland town offers a stark contrast to Vietnam’s tropical lowlands.

Seasonal Overview:

Best Time to Visit Sapa

Late April to early June is one of the best times to experience Sapa’s natural beauty, with blooming flowers and lush green terraces under clear blue skies. Alternatively, September to early October is magical as the rice terraces ripen into brilliant shades of gold just before harvest.

From December to March, the region turns chilly and atmospheric. While fog often blankets the valleys, the crisp mountain air adds a cozy charm. January may even bring rare snowfall, offering a unique perspective on Vietnam that few travelers get to see. Local hotels are well-prepared, with heated blankets and fireplaces. Don’t miss the traditional herbal baths offered by ethnic minority communities, perfect for warming up after a brisk hike.

Central Vietnam

Weather in Hoi An

With its lantern-lit streets, historic Old Town, and proximity to the sea, Hội An is one of Vietnam’s most charming destinations. Its tropical monsoon climate divides the year into two main seasons, dry and rainy, each shaping a different experience of this UNESCO-listed town.

Seasonal Overview:

• September to January: Rainy, cloudy, and cooler. Frequent showers and occasional flooding, especially in October and November.
• February to August: Warm to hot, mostly dry, and sunny. Perfect for sightseeing and beach days.

Best Time to Visit Hoi An

February to August is the best window to enjoy Hội An’s ancient town, nearby rice paddies, and coastal escapes. March is exceptionally lovely, as the town bursts with fresh blooms and vibrant greenery. From May to August, temperatures climb past 30°C (86°F), making a quick trip to An Bang Beach or Cua Dai Beach a refreshing break from the midday heat.

The rainy season, lasting from September to January, brings tropical storms, gray skies, and increased chances of localized flooding, particularly in the low-lying Old Town. October and November tend to be the wettest. While January marks the coolest temperatures of the year (around 18°C/64°F), things begin to warm up just in time for Tet, the Vietnamese Lunar New Year, usually celebrated in late January or early February.

Weather in Nha Trang

Famous for its turquoise waters, white-sand beaches, and laid-back coastal vibe, Nha Trang enjoys one of the sunniest climates in all of Vietnam. With over 300 days of sunshine per year, this beach city is a reliable destination for sunseekers and scuba divers alike.

Seasonal Overview:

• September to December: Rainy, cloudy, and cooler. Brief but noticeable monsoon season, with occasional storms.
• January to August: Hot, dry, and sunny. Long stretches of blue skies and high temperatures, especially from July to August.

Best Time to Visit Nha Trang

The ideal time to visit Nha Trang is from January to August, when the weather is consistently warm and clear. Sea breezes keep the coastline pleasant, even as daytime temperatures rise above 30°C (86°F). This is peak season for beach activities, island-hopping, and diving excursions around Hon Mun or Hon Tam islands.

Although the rainy season arrives between September and December, it tends to be shorter and less intense than in other regions of Vietnam. Showers are usually brief and followed by sun. However, October and November may see more persistent rain and the rare coastal storm.

Weather in Da Lat

Tucked away in Vietnam’s Central Highlands, Da Lat is often called the “City of Eternal Spring.” Known for its pine-covered hills, colorful flower gardens, and French colonial charm, Da Lat enjoys a temperate mountain climate that sets it apart from Vietnam’s tropical lowlands.

Seasonal Overview:

• April to October: Rainy, warm, and cloudy. Expect regular afternoon showers and misty mountain views.
• November to March: Cool to cold, dry, and crisp. Skies are generally clear, with chilly nights and mild days.

Best Time to Visit Da Lat

November to March is the best time to explore Da Lat, when the air is dry, the skies are clear, and temperatures range from 15°C to 25°C (59°F to 77°F). This is ideal for outdoor adventures like hiking Lang Biang Mountain, visiting the Valley of Love, or strolling through local markets without the heat or humidity.

During the rainy season (April to October), Da Lat becomes lush and green, with afternoon downpours and cloudier skies. While not the best for outdoor activities, this period still offers charm, especially for those drawn to misty landscapes and quieter streets. July tends to be the warmest month, reaching highs of 30°C (86°F), though the elevation keeps things relatively comfortable.

Southern Vietnam

Weather in Ho Chi Minh City & The Mekong Delta

In Southern Vietnam, including bustling Ho Chi Minh City and the fertile Mekong Delta, the climate is tropical and consistent year-round, with just two main seasons: wet and dry. While the temperatures don’t vary much, the weather patterns shift dramatically between sun-drenched days and short, heavy rains.

Seasonal Overview:

• May to November: Wet season is hot, humid, with predictable afternoon showers.
• December to April: Dry season is hot, sunny, with clear skies and lower humidity.

Best Time to Visit Ho Chi Minh City & The Mekong Delta

The dry season, from December to April, is the best time to explore Ho Chi Minh City, Can Tho, and the broader Mekong Delta. Days are bright, skies are clear, and temperatures average around 30°C (86°F). January and February are especially pleasant, with slightly cooler breezes and lower humidity, perfect for city tours, floating markets, and river cruises.

From May to November, the rainy season sets in. Daily afternoon downpours are often brief and refreshing and rarely last more than a couple of hours. While humidity is high, mornings are usually dry, and the lush countryside comes alive with greenery. This is also the season for tropical fruits and vibrant local festivals.

Weather in Phu Quoc

Located off the southwestern coast of Vietnam in the Gulf of Thailand, Phú Quốc Island is famed for its palm-fringed beaches, crystal-clear waters, and laid-back tropical vibe. The island enjoys warm temperatures year-round, but seasonal rainfall can impact travel plans, especially for beach lovers and ferry passengers.

Seasonal Overview:

• July to September: Rainy season is hot, humid, and stormy. Expect rough seas and heavy afternoon showers.
• October to June: Dry season is hot, sunny, and mostly clear skies. Ideal beach weather.

Best Time to Visit Phu Quoc

The best time to visit Phú Quốc is during the dry season, from October to June, when the island is bathed in sunshine and temperatures hover between 28–32°C (82–89°F). December and January are particularly idyllic, offering perfect weather for swimming, snorkeling, and lounging on Long Beach, Sao Beach, or exploring Phú Quốc National Park.

Avoid visiting between July and September, when the monsoon season can bring heavy rainfall and rough seas. Storms during these months often disrupt ferry services and make beach activities less enjoyable. That said, hotel prices are lower, and the island is much quieter, attractive for some off-season travelers.
