Vietnam Weather in January

January is generally regarded as the coldest month in Vietnam. But such cold weather is not unbearable. Due to its location within the subtropical and tropical climatic zones, even northern regions such as Hanoi rarely experience temperatures below 10 degrees Celsius (50 degrees Fahrenheit) in January. In contrast, southern areas, exemplified by Ho Chi Minh City, exhibit a complete summer scene, with daytime highs reaching up to 34℃ (93℉), making short-sleeved T-shirts perfectly suitable.

Furthermore, precipitation during January is minimal across the country. Hanoi and Ho Chi Minh City see no more than 10 rainy days each, and it is mostly scattered showers or sporadic light rain.

Cool in the North but Hot in the South

Vietnam spans more than 1,600 kilometers (994 miles) from north to south. Combined with its diverse topography and geographical features, regional temperature variations during January are considerable.

For instance, in Hanoi, the low temperature in January is around 15℃ (59℉), while the high temperature can reach 26℃ (79℉). That is to say, it is only a bit chilly in the early morning and evening when going out, so you need to put on a windbreaker. Further north in Sapa, the temperature is lower, possibly remaining below 10℃ (50℉).

The temperature in the south is much higher. For instance, in Ho Chi Minh City, the high temperature is generally around 30 to 34℃ (86 to 93℉). However, compared with the scorching heat of June to August, January weather conditions are better. As long as you take proper sun protection measures, outdoor activities remain feasible.

One of the Driest Months in a Year

Average precipitation: 43mm from 8 rainy days

Whether in the north or the south, January ranks among the driest months in Vietnam. In Hanoi, the total rainfall in January is only 19mm on average, with only 8 rainy days. In Ho Chi Minh City, it is even lower, with only 14mm of rainfall and just 2 rainy days. At this level, rainfall is typically so light that the ground does not become fully saturated, indicating that the rain does not influence your sightseeing a lot.

Does it snow in Vietnam in January?

Most parts of Vietnam have a tropical monsoon climate, remaining warm or hot throughout the year with no snow falls. However, in Sapa, a certain northern region influenced by the continental climate of the Chinese mainland, temperatures drop significantly in January, and snow falls occasionally.

Is January a Good Time to Visit Vietnam?

Yes, January is a great time to visit most parts of Vietnam as it is neither in the rainy season nor the typhoon season, and the climate is neither extremely cold nor hot, making both indoor and outdoor activities enjoyable.

However, pay attention to some places where the weather is slightly special. For instance, Ha Long Bay is different from other regions in Vietnam in that weather conditions are particularly changeable. Many tourists have reported that during January, the area is frequently covered by overcast skies, making it difficult to admire the deep blue water, and thus not a good time for a visit. Also, January is not a good time to visit cold Sapa, unless you are going there for snowy scenery.

How to dress for Vietnam in January?

Northern Vietnam:

For most areas, a hoodie or a bottoming shirt is enough. When engaging in outdoor activities in rainy days or in the early morning and evening, it is advisable to add a thermal outer layer like a jacket or a windbreaker. For the lower body, bring thick jeans or sweatpants. For shoes, sneakers and walking shoes are enough.

Note: If you plan to climb Fansipan in Sapa, where weather conditions can be harsh, a three-in-one waterproof and windproof performance jacket or a lightweight down jacket is highly recommended.

Southern Vietnam:

Most of the time, simple summer clothes like short-sleeved T-shirts and shorts are sufficient. Girls who want to take good-looking photos can also prepare a few pretty dresses. When the temperature is lower in the early morning and evening, a light jacket or a sun-protective coat will be fine. For shoes, you can choose sneakers or sandals.

Travel Tips in Vietnam in January

1. If you plan to visit Sapa in January of 2026, it is essential to keep a close eye on the weather forecast, as snow falls may occur. Maybe you will have the opportunity to witness a tranquil and picturesque view characterized by a blanket of snow. However, snow falls may also lead to operational disruptions. For example, those who wants to take the cable car to climb the Fansipan should check the official announcements in advance to confirm whether services are suspended due to adverse weather conditions.

2. In some areas in northern Vietnam, such as Sapa and Da Nang, there might be heavy fog with very low visibility, which is not suitable for outdoor sightseeing. In such cases, it is advisable to consider indoor options, such as a visit to the Da Nang Museum and Sapa Stone Church, for an enriching experience.

3. If you plan to visit weather-sensitive destinations like the seaside, it is recommended to choose sunny days. For instance, in Nha Trang and Da Nang, overcast days may prevent you from encountering the most beautiful glass-like sea.

4. When water temperatures fall below 25℃ (77℉), aquatic activities are not recommended, as they may increase the risk of hypothermia, muscle cramps, or respiratory discomfort. If you really want to participate in water-based activities, it is advisable to limit such activities to midday hours when temperatures are at their peak.
