Halong Bay in November: Weather, Sea Conditions and Cruise Tips

Hermes Premium Cruises sailing across calm emerald water in Halong Bay in November

Visiting Halong Bay in November places your voyage right in the heart of northern Vietnam’s golden autumn window. Summer heat and heavy tropical showers have given way to crisp, dry air, comfortable daytime warmth and calm emerald channels sheltered by around 1,600 limestone islands and islets.

Whether you prefer the intimate 18-cabin Hermes Cruises (where every suite has a private balcony and jacuzzi bathtub) or the 26-cabin Hermes Premium Cruises launched in 2026 (with its outdoor Infinity Pool and Royal Suite of 65 m²), this guide explains November weather figures, daily sea conditions, how both vessels schedule their shore stops, and what to pack.

Halong Bay in November offers some of the clearest, calmest cruising weather of the year. Vietnam’s tourism authority names September to November as the prime season, while nearby Haiphong climate normals show highs around 25 °C to 25.7 °C, lows near 19 °C, low rainfall (about 40–43 mm over 6 days) and over 5 hours of daily sunshine — ideal for kayaking, cave walks and sundeck sunsets on Hermes Cruises and Hermes Premium Cruises.

What Is the Weather Like in Halong Bay in November?

Halong Bay in November is warm and dry by day, pleasantly cool in the evening, and far sunnier than the winter months that follow. Vietnam’s national tourism website specifically highlights September to November as the best time to visit Halong Bay thanks to clear, calm autumn skies.

Because Tuan Chau International Port does not publish a standalone meteorological table, the most reliable climate benchmark is Haiphong, located 40 km from the cruise pier. Both Climates to Travel and Wikipedia’s climate table for Haiphong (citing the Vietnam Institute for Building Science and Technology) show why November is so comfortable on deck.

November Climate Metric (Haiphong Benchmark) Climates to Travel Wikipedia (VIBSTE Data) What It Feels Like on Board
Mean daily maximum 25 °C 25.7 °C Warm enough for kayaking, cave walks and afternoon deck lounging
Mean daily minimum 19 °C 18.9 °C Refreshing evening air for outdoor dining and squid fishing
Monthly rainfall 40 mm 43.2 mm One of the driest months of the year after summer rains end
Rainy days 6 days 6.3 days Mostly dry days with occasional brief passing showers
Sunshine hours ~5.5 hours/day 162.1 hours/month Crisp golden light for photography at Sung Sot Cave and Titov Island
Relative humidity Moderate 78.0% Noticeably drier and fresher than June–August

According to the IUCN World Heritage Outlook, the wider World Heritage property encompasses around 1,600 islands and islets. In November, low humidity and gentle winds allow guests to see deep across those limestone karst ridges from the sundeck and private cabin balconies.

Sea Conditions and Visibility: Why November Suits Every Activity

November brings calm, sheltered water across Halong Bay, making tender transfers, kayaking at Luon Cave and climbing Titov Island comfortable from morning to dusk. Because the tropical summer storm season winds down by late autumn and winter mist has not yet settled in, November combines stable sea conditions with bright visibility.

Three practical advantages stand out during a November sailing:

  1. Comfortable temperature for climbing and paddling. At 25 °C by afternoon, walking up to Sung Sot Cave or climbing the 424 stone steps of Titov Island feels brisk rather than humid, and paddling a kayak through Luon Cave is pleasant in a T-shirt.
  2. Clear sunset hours on the sundeck. With over 5 hours of daily sunshine on average, late-afternoon light between 16:30 and 17:30 turns the limestone cliffs warm gold — right when both Hermes vessels host their sunset gatherings on deck.
  3. Cool, restful nights at anchor. Evening lows around 19 °C mean you can sit out on your private balcony or join squid fishing at 21:00 with only a light cardigan or windbreaker.

⚓ Captain’s Maritime Log:
“November sits in the sweet spot between summer showers and winter mist. Visibility across the channels around Bo Hon Island and Titov Island is typically clear from early morning Tai Chi right through sunset, and the sheltered waters inside the bay keep the ship steady at anchor.”

Experiencing November on Hermes Cruises (18 Cabins) vs Hermes Premium Cruises (26 Cabins)

Both vessels in the Hermes fleet sail from Tuan Chau in November and cover the core icons of Halong Bay — Sung Sot Cave, Luon Cave and Titov Island — while offering two distinct ship styles and daily rhythms. Choosing between them comes down to whether you prefer a classic 18-suite boutique boat where every cabin has a private balcony and indoor jacuzzi, or a newer 26-cabin vessel with an outdoor Infinity Pool.

Notice how smartly the two ships stagger their shore visits:
– On Hermes Cruises, you paddle Luon Cave and visit Titov Island in the warm afternoon light of Day 1 (14:00–16:20), then walk through Sung Sot (Amazing) Cave in the cool morning air at 07:30 on Day 2 (or Day 3). You can review the full schedule on the 2 Days 1 Night itinerary on Hermes Cruises and compare all 9 suite types on the Hermes Cruises cabins & suites page.
– On Hermes Premium Cruises, you explore Sung Sot Cave and Luon Cave on Day 1 afternoon at 14:30, return at 17:00 for sunset tea and a cooking class, and visit Titov Island at 07:15 on the final morning. See the 2 Days 1 Night itinerary on Hermes Premium Cruises and the 7 room layouts on the Hermes Premium cabins & suites page.

If your November schedule allows two nights on the bay, both ships offer a 3 Days 2 Nights programme that spends Day 2 in quieter Lan Ha Bay (Trinh Nu Cave and Ba Trai Dao beach) — compare the 3 Days 2 Nights itinerary on Hermes Cruise and the 3 Days 2 Nights itinerary on Hermes Premium Cruise.

🧭 Cruise Director’s Insider Tip:
“November is one of our busiest autumn months because the weather is so reliable. If you have your eye on a specific top-tier suite — such as the two President Suites of 64 m² with round beds on Hermes Cruises or the two Royal Suites of 65 m² with private outdoor Jacuzzis on Hermes Premium — reserve early so your preferred deck and room category are locked in.”

November vs October vs December in Halong Bay

November sits between the warmer late-summer feel of October and the cooler, mistier winter days of December. All three autumn-to-winter months are popular with international travelers, each with a slightly different character.

Month Daytime High / Night Low Rain & Sky Character Best For
October ~28 °C / ~22 °C Warm sunshine, transitioning into dry autumn Swimming, sundeck lounging and clear photography
November ~25 °C / ~19 °C Crisp, dry air (~40 mm rain), 5+ hours of daily sun All-round comfort: cave walks, kayaking, sunset tea and balcony dining
December ~22 °C / ~16 °C Cooler, dry (~20 mm rain) with atmospheric winter mist Quiet winter scenery, festive Christmas & New Year sailings

What to Pack for a Halong Bay Cruise in November

Pack breathable daywear for 25 °C afternoons, closed walking shoes with grip for cave steps, swimwear for kayaking or the pool, and a light jacket for 19 °C evenings and 06:00 Tai Chi.

  • Travel documents: Your passport (valid for at least 6 months beyond entry, per Vietnam’s visa requirements) and travel insurance as advised by GOV.UK.
