Ha Long Bay in winter

When is the winter season on Ha Long Bay?

From 1 November to 31 March for sailings: boats leave port from 5.30am and are back by 7pm. The caves and islands keep winter hours from 1 November to 15 April.

The Ha Long Bay Management Board sets two timetables a year. In summer, from 1 April to 31 October, boats may leave from 5am and have until 8pm to return. Winter trims an hour and a half off that window. The caves follow their own calendar and close 30 minutes earlier in winter: Sung Sot Cave, Ti Top island and Luon Cave take visitors from 7.30am to 5pm.

For a day cruise this barely shows. The boats board around 11.30am and the listings already fit Sung Sot, Luon and Ti Top into the afternoon. Overnight cruises feel it more at the end of the day: sunset comes early, and the sunset party on deck moves with it.

What is the weather like on Ha Long Bay in winter?

Cool and fairly dry. Ha Long averages about 17.8°C in December, 16.1°C in January and 16.6°C in February, with 19 to 25 mm of rain in those months.

Compare that with August, when Ha Long averages 445 mm of rain. Winter is the dry half of the year. Wikipedia's climate article describes winters in the Northeast region, which includes Quang Ninh, as cold and cloudy with little sunshine and frequent drizzle, under the northeast monsoon.

That cloud is part of the look. The karsts fade into each other in layers of grey and green. Cold spells in the north tend to bring drizzle and early-morning fog: the national forecasting center flagged both for the New Year week of 2025-26, as VietNamNet reported. Blue-sky photos are more of a summer thing. Moody ones are winter's.

What will winter 2026-27 be like?

Warmer than usual, if the forecast holds. The National Center for Hydro-Meteorological Forecasting expects December and January to run 0.5 to 1.5°C above the long-term average.

VOV reported the outlook on 1 November 2026. The center expects cold air from the north to be weaker than average this winter, with severe cold arriving later than usual and on fewer days. It puts the cause on a very strong El Niño. A milder season still leaves room for short, sharp cold snaps, and the center says so.

What that means on a boat: plan for the averages in the table above, and keep a warmer layer in the bag for the evening. The listings say itineraries can change with the weather, and the Lan Ha day cruise promises a full refund if a sailing is cancelled.

Can you kayak and swim on Ha Long Bay in winter?

Kayaking, bamboo boats and the caves run all year on every listing. Swimming is on the programs too, but in January most people will want a pool or a jacuzzi instead.

Nothing on the listings changes for winter. The day cruise still offers a kayak or bamboo boat through Luon Cave and the beach at Ti Top. The 2-day boats still run squid fishing, a cooking class and tai chi on deck at sunrise, and the Lan Ha programs still kayak at Ao Ech.

The pool is where winter shows. The Elite cruise lists a four-season pool with a spa and sauna, and the 2-day Ha Long and Lan Ha cruise has a pool or jacuzzi. A hot drink inside, by the window, is the other winter pleasure.

What should you pack for Ha Long Bay in winter?

Layers. The listings ask for comfortable shoes, sunglasses, a sun hat, sunscreen and your passport or ID; in winter add a warm top and a windproof jacket for the deck.

The top deck gets the wind, and boat speed adds to it. A fleece and a light jacket cover most days. You still want sunglasses and sunscreen, because the light off the water is bright even under cloud. Wear shoes with grip for the cave paths and the steps up Ti Top.

Bring a reusable bottle: several boats ban plastic bottles, and the luxury day cruise has no refill on board. For the full list by cruise type, see our what to wear and pack guide.

Is winter a good time for a Ha Long Bay cruise?

Yes, if you like cool air and soft light. The summer storm season is over, rain is low, and a night on board makes the most of the shorter days.

Wikipedia's climate article places the storm season in summer, and the rainy season in the Northeast usually from May to September. Winter trades blue skies for calm, misty mornings. If you want the quieter side of the bay, the Bai Tu Long Bay cruise heads north-east to Thien Canh Son Cave and the islands of Cong Do and Cap La.

One thing to plan for: the peak-season charges on two Bai Tu Long listings run from 1 October to 30 April, and the holiday dates bring surcharges of their own. See this year's prices and the holidays post. For the season-by-season view, read our guide to when to go.
