For travellers who want to experience Van Don Bay, Oris Cruise is one of the top choices. It is the first cruise to explore this off-the-beaten route, taking guests beyond the more familiar Halong Bay itineraries to pristine places such as Cai De and Phat Co Cave, alongside more immersive local and nature-based experiences.
Spring
- Best for: Beach days, island hopping, seafood experiences, and outdoor photography.
Spring (March to May) marks the transition from Van Don’s cooler, drier winter into warmer weather. It gets increasingly sunny, with occasional showers. Average temperature rises from around 24°C in March to 28°C in April and 32°C in May, while rainfall increases from about 55 mm to 185 mm. Humidity stays relatively high at 78 - 82%, but outdoor conditions are still comfortable, particularly in March and April.
Sea conditions are generally suitable for cruising, swimming, and island excursions; the sea becomes warmer toward May. Visibility is mostly great. Outdoor comfort is best in March - April; May is warmer and more humid, especially around midday.
Seafood season is in full swing - this is the exact window when local fishermen bring in the freshest squid and sea cucumbers.
Tips: Book ferry tickets and island accommodations at least 3 weeks in advance if travelling on May weekends.
Summer
- Best for: Swimming, beach holidays, water activities
Summer (June to August) is the hottest and rainiest part of the year in Van Don. Average highs reach around 34°C in July. Summer has long daylight hours (up to 12 hours). Monthly rainfall is high, rising from roughly 196 mm in June to 299 mm in July and 381 mm in August. Showers can be frequent in the afternoons.
Humidity remains around 74 - 86%, so beach days can feel excellent in the morning, but humid around noon. Beach conditions are amazing on sunny days, with cool seas and stable waves. Island excursions are also enjoyable when the sea is calm, but potential heavy rains/storms/typhoons can affect outdoor activities, especially in July & August.
Advice: If you visit in July or August, stay flexible! Always keep a 1-day buffer before any international flight out of Hanoi. If you prefer zero island stranded-risk, stay at mainland resorts like InterContinental Halong Bay Resort, DeLaSea Ha Long, Vinpearl Resort & Spa, etc., where you can enjoy luxury pools and ocean views regardless of ferry schedules.
Autumn
- Best for: Scenic cruising, kayaking, photography, island sightseeing
Fall (September to November) brings a noticeable change in Van Don weather as the weather gets cooler and milder compared to summer. Temperatures gradually fall from average highs of around 30°C in September to 24°C in November, while rainfall drops sharply from about 244 mm in September to just 46 mm in November. Humidity also falls to a comfortable level around 72%.
Sea conditions are increasingly comfortable as autumn progresses, with clear skies, calm waves, fresh breeze, and outstanding visibility. September and October remain warm enough for swimming; November feels cooler, particularly in the water.
Advice: This is an excellent period for cruising Bai Tu Long Bay, kayaking through limestone caves, and enjoying photography in softer autumn light. By mid-November, the water can start to feel fresh for swimming, so it is worth shifting your focus toward scenic cruises, cycling around Minh Chau, exploring local villages, and lingering over seafood dinners.
Winter
- Best for: Wellness escapes, cultural activities, photography, and peaceful off-season travel
Winter (December to February) is not a “bad” season for Van Don; it simply offers a different kind of trip that is much more peaceful and soothing. The weather is cool (sometimes cold) and dry, about 18 - 22 °C, with relatively little rain. Humidity is also low, around 68 - 76%, and mist is frequent in the morning.
Cooler winds and occasional cloudy days make it less attractive for swimming, but the quieter atmosphere is ideal for relaxation, food and wellness experiences.
BestPrice Travel’s Advice: Winter is an excellent opportunity to combine Van Don with a seafood and hot-spring wellness journey. After enjoying a seafood hotpot around Cai Rong Port, continue to Yoko Onsen Quang Hanh, about 35 km from Van Don and around 40 minutes by car on the way back to Hanoi, for a Japanese-style hot-spring and spa experience.
We particularly recommend this route for international and mid-range travellers who want more than a beach holiday. You can also add Cai Bau Pagoda (Truc Lam Giac Tam) for a relaxed combination of coastal scenery, local culture, seafood, and wellness without rushing between attractions.
