Planning a trip to Bac Ninh? In this section, you'll find up-to-date weather information and detailed forecasts to help you perfectly plan your visit to this colorful corner of Vietnam.

The city of Bac Ninh, located in northern Vietnam, is influenced by a tropical monsoon climate. This region is characterized by a distinct change of seasons: a cool and relatively dry period lasts from October to April, while the hot and humid season spans from May to September. This climatic rhythm shapes not only the natural environment but also the city's lifestyle.

The overall weather pattern is dictated by the monsoons. In winter, northeastern winds bring dryness and a pleasant coolness, creating comfortable conditions for long walks and sightseeing. In summer, southwestern flows prevail, bringing heavy rainfall and high humidity, which contributes to the incredibly lush greenery of the surroundings. The average annual temperature here is around 26°C.

Travelers should expect clear days during the dry season, while in the rainy season, the sky is often overcast and the air becomes truly muggy. Nevertheless, every season in Bac Ninh has its own unique charm and is suitable for different types of tourist activities.

The temperature chart in Bac Ninh shows significant fluctuations throughout the year. The hottest period is summer, especially from June to August. During this time, the average high is around 32–34°C, and on certain days, the mercury can rise above 40°C. Due to high humidity, the heat during this period can be quite taxing and feels more intense than the actual reading.

The winter period in the city is characterized by mildness but can be surprisingly cool. In December and January, the average nighttime temperature drops to 14°C, while during the day, the air warms up to a comfortable 20–21°C. This time is considered the most pleasant for those who do not handle intense heat well. In the province's foothill areas, light ground frost is even possible during this time.

An important feature of the Bac Ninh climate is the diurnal temperature range, which is most noticeable during the dry season. During the day, the sun can heat the air to 28–30°C, while refreshing coolness arrives after sunset. In the rainy season, the difference between daytime and nighttime temperatures is less pronounced, and the warm, humid atmosphere persists throughout the 24-hour period.

The precipitation pattern in Bac Ninh follows a strict seasonality dictated by the monsoons. Most of the annual rainfall occurs between May and October. August and September are traditionally considered the wettest months, when rainfall can reach up to 408 mm. During this time, rain is frequent—up to 25 days a month—but it usually takes the form of intense, short-lived downpours.

The dry season, beginning in October, brings noticeable relief. The "driest" months are December, January, and February, when precipitation levels are minimal (only 27–60 mm per month). During this period, the sky is most often clear, and if it does rain, it is usually just a light, barely noticeable drizzle.

Although summer rains can be very heavy, they rarely last all day, often giving way to bright sunshine. In the province's mountainous areas, there is even less precipitation during the winter months, but thick morning fogs can occur due to high humidity. Travelers are advised to note that about 80% of all annual precipitation falls during the summer-autumn period.

When heading to Bac Ninh during the dry season (October – April), lightweight clothing should form the core of your wardrobe, but be sure to bring a jumper or a light jacket. Evenings and nights during this period can be quite cool (down to 14–20°C). Don't forget sunscreen and a hat—the sun remains strong even in moderate temperatures.

For a trip during the rainy season (May – October), lightweight items made of natural cotton that dry quickly are critical, along with a reliable umbrella or waterproof raincoat. Pay special attention to footwear: it should have good grip for moving comfortably along wet streets. The layering principle will be useful during transition months when the weather can change several times a day.

Useful accessories year-round include insect repellent and sunglasses. If your trip is planned for the peak of the summer heat (June – August), when temperatures reach 34°C, it's worth considering clothing with UV protection. Also, always keep a bottle of water with you to better handle the high tropical humidity.
