Ha Long in April is where nature begins to bloom in full swing, offering a gentle transition between spring freshness and early summer warmth. The bay sheds its winter mist and welcomes longer days, clearer skies, and calm turquoise waters. With the weather at its best, April is also a quieter time before the summer tourist rush, giving travelers the space to truly enjoy the bay’s serenity. Whether you’re planning a romantic escape, a family adventure, or a cultural retreat, Ha Long Bay in April delivers the ideal blend of comfort, beauty, and authenticity. In this guide, we’ll walk you through everything you need to know—from weather conditions and top activities to local food and practical tips for making the most of your trip.

Weather in Ha Long in April

Average temperatures range from 22°C to 28°C (72°F to 82°F) at this time of year, making it a great time for sightseeing, outdoor activities, and overnight trips. 

April is also one of the best months to visit because the days are longer, there is more sunshine, and it rains little to a bit. There may be light rain or short showers, but they usually don't last long enough to mess up trip plans. The skies are usually clear or slightly cloudy, which makes it easy for people to see the limestone karsts in the bay.

The sea stays quiet and is good for cruising, so you can kayak, swim, and find secret caves and beaches. In April, you can enjoy warm, sunny weather while still not being too many tourists. This makes it one of the best months to visit Ha Long Bay.

Must-Try Dishes in Ha Long in April

No trip to Ha Long is complete without sampling its unique and flavorful local cuisine. In April, as the weather warms up but remains pleasant, hearty coastal dishes and fresh mountain flavors hit just the right note. Here are some specialties you shouldn’t miss:

Xôi trắng chả mực

This iconic Ha Long dish brings together two simple yet flavorful elements: sticky white glutinous rice and chả mực (fried squid cake). The squid used is freshly caught from the bay, finely ground, then hand-pounded and fried until golden brown and slightly crispy on the outside, while remaining chewy and rich inside. Served with a sprinkle of fried shallots and optional chili sauce, it’s a filling and satisfying breakfast or snack — deeply connected to Ha Long’s coastal identity.

Sá sùng khô (Dried Peanut Worms)

Once a food reserved for royalty, sá sùng is one of the most prized seafood delicacies of Quang Ninh. These sand-dwelling marine worms are harvested in Van Don and dried naturally under the sun. When stir-fried with garlic or added to hotpot, sá sùng releases a natural sweet, umami flavor that enhances the entire dish. Though a bit pricey, it’s a must-try for foodies looking for something rare and deeply local.

Gà đồi Tiên Yên (Tien Yen Hill Chicken)

Raised freely on the hills of Tiên Yên district, this free-range chicken develops lean, firm meat with a natural sweetness and great texture. The most popular ways to enjoy it are steaming (to retain the original flavor) or roasting with honey or lime leaves. It’s often served with just salt, pepper, and lime juice to highlight its quality. In local restaurants, you’ll often find it paired with sticky rice or a bowl of hot herbal soup.

Ốc móng tay xào rau muống (Stir-fried Razor Clams with Water Spinach)

A flavorful and popular seafood stir-fry, ốc móng tay xào rau muống is beloved for its satisfying texture and fragrant garlic-infused aroma. Razor clams, known for their tender yet slightly chewy meat, are stir-fried quickly over high heat with water spinach (rau muống), garlic, and a splash of fish sauce or oyster sauce. The dish is usually served hot, sizzling right out of the wok, and pairs wonderfully with steamed rice or cold beer. It’s especially popular in seaside eateries and night markets throughout Ha Long, offering a perfect balance of land-and-sea freshness in every bite.

Ngán nướng/hấp (Grilled or Steamed Ngán Clams)

Ngán, a type of clam native to the mangrove areas around Ha Long, has a unique flavor — sweet at first, followed by a slight bitterness that seafood lovers appreciate. In April, when the weather is mild, ngán is often grilled over charcoal or steamed with lemongrass, releasing a delicate aroma. Its extract is also fermented into rượu ngán, a specialty liquor that packs a punch and is often served at seafood feasts.

Rượu nếp Hoành Bồ (Hoanh Bo Sticky Rice Wine)

This traditional glutinous rice wine comes from the Hoành Bồ region near Ha Long, made by fermenting sticky rice with forest leaves and natural herbs. The result is a mildly sour, aromatic wine that locals believe aids digestion and balances seafood-heavy meals. Typically served at room temperature in small ceramic cups, rượu Hoành Bồ is a perfect pairing with grilled squid, snails, or even dried sá sùng.
