Halong Bay weather in November — background and climate facts
November marks the transition toward the region's winter period. Official climate figures for the month typically show an average air temperature near 22 C, daytime highs around the mid-20s, and nighttime lows that can drop into the high teens. Humidity tends to fall from peak-summer levels and many datasets list average relative humidity at about 77% for November.
Rainfall in November is substantially lower than in the wet season. Recorded precipitation averages about 12 mm with roughly eight days of measurable rain during the month, making it one of the driest months of the year in Halong Bay. Sea temperatures often remain warm, near 28 C, so water activities are still possible for most visitors.

Key features and highlights for November visits
Lower rainfall and milder temperatures make November a good month for boat-based sightseeing and outdoor excursions. Cruising around the limestone islands, visiting caves and stopping at small fishing communities are activities that benefit from clearer skies and calmer seas. Visitors report better visibility for photography and more comfortable conditions for daytime hikes.
Sea conditions in November are usually favourable for swimming and short kayak outings because the water stays relatively warm while winds are often lighter than in winter peak months. For information about the range of boat types and how they differ, consult this boat guide which covers options commonly used around Halong Bay and other Vietnamese waterways.
- Overnight and day cruises — cruising remains the most popular way to see the bay.
- Cave visits — many caves are accessible and cooler inside, offering relief from daytime sun.
- Floating village visits — cultural encounters with local fishing communities.
- Island hikes — short climbs to viewpoints are comfortable in November's temperatures.
- Kayaking and swimming — usually possible, but check local conditions before entering the water.
Practical tips for travel and packing
Packing for November should balance warm daytime clothing with layers for cooler evenings. Lightweight shirts, a light jumper or fleece for night, and a windbreaker are sensible choices. Because the sun still has strength, sunscreen, a hat and sunglasses remain useful.
Booking advice: November is often a popular month for international visitors, so if you have fixed dates it helps to reserve cruises and accommodation in advance. Visitors who plan to stay on Cat Ba Island or use it as a base should consider local lodging options early; this guide to where to stay on Cat Ba explains the range of hotels and guesthouses available.
- Bring a light sweater and scarf for evenings and open-deck cruise time.
- Pack swimwear and a quick-dry towel if you intend to swim or kayak.
- Waterproof dry bags are useful for electronic devices when you take small boats or kayaks.
- Comfortable walking shoes for short hikes and cave walks.
- Book cruises two to three months ahead for the best selection during peak demand.
Cultural context and local experiences
Halong Bay is home to small fishing communities that have lived in the sheltered waters for generations. Visits to floating villages offer a different perspective from land-based towns: visitors can observe daily activities such as fish farming, net mending and local markets. Most travellers report cordial interactions when visiting these communities; always follow local guidance and ask before photographing people or private property.
Onshore cultural stops include regional museums and small exhibit spaces that explain local geology, history and ethnic traditions. Sampling local beverages — tea and coffee prepared in regional styles — is a common part of both city and cruise experiences; these offer a quiet window onto daily life and the preferences of local hosts.
Who benefits from visiting in November and alternatives
November suits travellers who prefer fewer heavy showers and more temperate air for outdoor activities. It can be a good match for families with older children, couples avoiding summer heat, and visitors interested in combining boat time with light hiking. Those sensitive to evening chill should bring warm layers for overnight stays or open-deck moments.
If you need warmer water or even drier conditions, consider checking conditions for late spring months; conversely, travellers prioritising lower visitor numbers might look at shoulder months on either side of peak season. The table below compares October, November and December figures often cited in regional climate summaries so you can weigh timing for your trip. Note: some datasets present slightly different average values for November; as a rule, expect daytime highs in the mid-20s and cooler nights.
| Month | Average temp ( C) | Rainfall (mm) | Relative humidity (%) |
|---|---|---|---|
| October | 24.5 | 54 | 72 |
| November | 25 | 12 | 77 |
| December | 19 | 22 | 66 |
