Weather in Vietnam

Vietnam is often depicted as a place with steamy jungles and hot beaches, but country’s climate is quite diverse, with freezing temperatures and even snow in its northern highlands. Vietnam has two distinct monsoon seasons. The southwest monsoon brings in wet and humid weather while the northeast monsoon delivers drizzly, colder temperatures to the north and dry weather to the south. Northern Vietnam has four seasons: during its winter months December-February, it may dip down to 5-6°C occasionally, even below zero in mountainous areas. The summer months of June and July are hot, with daytime temperatures reaching 35°C. Drizzling rains and more pleasant temperatures come in autumn, August-November, and the spring, March-April. Central Vietnam has warm temperatures year round, with the hottest months in middle of the year, and cooler, drier days from November to April. Southern Vietnam has a dry season from November to April and a wet season from May to October. Overall, Vietnam enjoys a mild tropical or subtropical climate and aside from a few months a year in the high northern region you’ll never need to worry about packing cold-weather gear. But do bring an umbrella, especially if visiting from July to November, Vietnam’s stormiest months.

Vietnam is geographically located in the tropical zone, with the top North region on temperate zone. Therefore, its climate is not consistent throughout the country. In fact, the weather varies significantly by latitude and longitude.

The North (Hanoi, Halong Bay) is monsoonal with hot and rainy season from April to September and cool dry season from October to March. October and November are the best months to visit since you avoid the domestic tourist flow and also experience a more comfortable temperature and humidity compared with other months.

The Central part of Vietnam (Hue, Da Nang and Hoi An) receives dry and hot Southwest wind which makes it strenuous for any brisk walk during the day. Closer to the beach, the level of severity reduced and the dry wind is replaced by cool ocean breeze.   Because of the limited land area, central Vietnam is also most susceptible to natural disasters such as hurricane or flooding. The paradox is, it is also where most beautiful beaches lie.

The South (Ho Chi Minh City, Nha Trang, Mui Ne) is typically hot all year round with two main seasons: rainy and dry. It is also the most predictable region in terms of weather. Summer months from May to August might not be the best time to hit the road since most tourists destinations are packed with tourists and downpours happen quite frequently.

The mountain area in Northwest and South central Vietnam see little fluctuation in weather condition. It is fairly cool all year round and a great place to escape the heat from cities. The rainy season is also from May to September. At the extreme you can see snow or flurry in December or January in Sapa .
