What is the weather like in Halong Bay in January?
January brings winter weather to Halong Bay, but it’s generally mild and pleasant. The temperature usually stays around 16°C (61°F) during the day. Mornings start cool at about 12°C (54°F), but the afternoon sun warms things up to a comfortable 20°C (68°F).
The air feels fresh and clean in January because the humidity drops to its lowest point of the year (60-65%). This creates perfect conditions for taking photos of the limestone cliffs, as the air is clear and visibility is excellent.
Rain is rare in January – you’ll only see about 15-20mm of rainfall throughout the month. Most days have clear skies, though you might occasionally catch a light drizzle during your stay. The sun shines for 3-4 hours each day, giving you plenty of light for activities between sunrise (6:15 AM) and sunset (5:45 PM).
The water temperature stays surprisingly warm at 21°C (70°F). While this is the coolest it gets all year, the bay’s protected location helps keep the water temperature stable.
One thing to watch out for is the winter winds from China. Local people call these “gió mùa đông bắc” (northeast monsoon winds). These winds can make the temperature drop suddenly to 8°C (46°F) or lower for 2-3 days at a time.
Is this worth visiting Halong Bay in January?
January offers a special experience that makes Halong Bay worth visiting. The cool weather and clear skies create perfect conditions for sightseeing and photography. While you won’t get the warm beach weather that summer brings, you’ll enjoy better visibility, fewer rain showers, and more comfortable temperatures for outdoor activities.

Must-do activities for visiting Halong Bay in January
Take an overnight cruise
January’s weather creates perfect conditions for cruising. The cool breeze makes sitting on the deck pleasant all day long. Morning cruises offer views of mist rolling between islands, while afternoon trips let you watch the sun paint the limestone cliffs in golden light.
Most cruises provide warm blankets for early morning tai chi sessions on deck. The clear winter air helps you spot eagles soaring between the islands and fishing boats in the distance.
Visit the caves
The winter weather makes cave exploration especially pleasant in January. The cool air makes the walk up to cave entrances comfortable, and the caves maintain steady temperatures year-round. Here are the must-visit caves in Halong Bay:
- Sung Sot Cave (Surprise Cave): This three-chamber cave system stretches over 10,000 square meters, and its huge chambers protect you from any winter winds.
- Luon Cave: The entrance to Luon Cave sits just above the waterline, and you can explore it by kayak or bamboo boat through a limestone tunnel that leads to a hidden lake surrounded by steep cliffs where monkeys sometimes appear in the morning.
- Dark and Bright Cave: This cave system features two distinct sections – a dark cave that you paddle through in complete darkness, and a bright cave that opens into a lake filled with colorful coral where you can spot different fish species in the clear winter water.
- Thien Cung Cave: Thien Cung (Heavenly Palace) Cave sits 25 meters above sea level and contains some of the bay’s most detailed rock formations – the cool January temperatures make the climb much more enjoyable than during the summer months.
- Thien Canh Son Cave: Located in Bai Tu Long Bay, this cave shows off impressive stalactites and stalagmites, and the clear winter air helps you spot the small details in the limestone formations that local people say look like different animals.
Kayak
January’s calm waters make kayaking a joy, especially in the morning when the bay looks like glass. You can paddle into hidden lagoons that larger boats can’t reach. Local guides know special spots where limestone walls create natural wind barriers, letting you explore even on breezy days. The cool weather means you won’t overheat while paddling, and the clear skies let you see fish swimming in the water below.
Take photos in the morning
Photographers love January mornings in Halong Bay. The mist usually starts thick at sunrise, then slowly reveals the islands as it lifts. This creates layers of depth in photos that you can’t capture in other seasons. The low humidity means your camera lens won’t fog up, and the soft winter light adds beautiful colors to morning and evening shots.he rocks appearing through the fog.
Meet local fishing families
January gives you a chance to see how fishing families prepare for Tet (Lunar New Year). Visit Cua Van village to watch people clean and decorate their floating homes. In Vung Vieng village, you can see how pearl farmers protect their oyster beds during winter. Many families still fish during this season, and they often dry squid and fish on their boat decks to preserve them for Tet celebrations.
