1. Overview of Vietnam’s Geography and Climate
Vietnam is located in Southeast Asia, on the Indochina Peninsula, spanning from approximately 8° to 23° North latitude and 102° to 109° East longitude.
1.1. General Characteristics
Lying entirely within the tropical monsoon region, Vietnam experiences a diverse climate due to its vast latitudinal range and varied topography. The northern regions, especially the mountainous areas, have a subtropical climate, while the south remains consistently tropical.
Because of these geographical factors, Vietnam’s weather can be unpredictable—some years see early or late winters, unusually heavy rainfall, droughts, or fluctuating typhoon activity.
1.2. Seasonal Variations
Vietnam’s climate is heavily influenced by the Asian monsoon system, resulting in two primary seasons:
- Rainy season (May–October): Dominated by the southwest monsoon, bringing heavy rainfall, especially in the southern and central highland regions.
- Dry season (November–April): Controlled by the northeast monsoon, carrying cool, dry air from mainland China, most noticeably affecting northern Vietnam.
1.3. Temperature & Humidity
- Average temperatures range from 22°C to 27°C , with northern Vietnam experiencing colder winters, sometimes dropping below 10°C
- Rainfall is substantial, averaging 1,500–2,000mm per year.
- Humidity remains high, typically above 80%, Contributing to the region’s damp and intensely cold conditions in winter of northern Vietnam.
2. Climate by Region
Vietnam’s climate varies significantly across its three main regions due to its long, narrow geography and diverse landscapes, from coastal plains to mountainous highlands.
2.1. Northern Vietnam
Northern Vietnam experiences four distinct seasons:
Spring (February–April)
- Temperature: 15–25°C, mild and pleasant.
- Characteristics: High humidity, frequent drizzle, and misty conditions. The combination of persistent light rain and moisture accumulation (known as nồm in Vietnamese) often makes homes and streets feel damp and uncomfortable.
- Travel Experience: Despite the humidity, this is a great time to witness blooming flowers and participate in traditional festivals. If you’re interested in Vietnam’s cultural heritage, spring is ideal for exploring historic sites and joining local celebrations.
- Recommended Destinations: Hanoi, Ninh Binh, Ha Giang, Dien Bien
Summer (May–August)
- Temperature: 28–40°C. In major cities, road surfaces can reach up to 50°C during peak heatwaves.
- Characteristics: Hot and humid, with sudden downpours and thunderstorms. July and August often bring typhoons, affecting coastal and lowland areas.
- Travel Experience: The best time for beach getaways or highland retreats to escape the heat. Vietnam’s northern beaches and mountainous areas offer great relief from the scorching temperatures.
- Recommended Destinations: Ha Long Bay, Cat Ba Island, Sapa, Moc Chau
Autumn (September–November)
- Temperature: 20–28°C, cool and comfortable.
- Characteristics: Clear blue skies, low humidity, and mild temperatures. The early mornings and nights can feel slightly chilly towards the end of the season.

- Recommended Destinations: Hanoi, Mu Cang Chai, Ha Giang.
Winter (December–February)
- Temperature: 5–18°C; mountain areas can drop below 0°C with occasional frost or snow.
- Characteristics: Cold and humid, with biting winds when the northeast monsoon is strong. The damp air makes the cold feel even more intense, especially in cities without central heating.
- Travel Experience: If you want to experience Vietnam’s winter scenery, this is the time to visit. Mountainous regions may have rare snowfall, and the cold weather makes street foods like pho and bun cha even more enjoyable.
- Recommended Destinations: Sapa, Mau Son, Ha Giang.
