Nha Trang In March: Weather, Snorkelling, What To Do 2027

Nha Trang in March is an ideal time to enjoy blue sea, sunshine and outdoor activities. If you are looking for a peaceful place to stay, Whale Island Resort on Hon Ong island in Van Phong Bay is well worth the trip, with bungalows right by the sea, beautiful coral snorkelling and quiet, relaxing moments in unspoilt nature.

Is Nha Trang Vietnam weather in March good?

Climates to Travel describes the March sea in Nha Trang as “pleasantly warm” and good for long swims. TIsland ranks March and April as the two best months of the year for most travellers, with calm sea and underwater visibility of around 15–20 m. So once Lunar New Year (Tet) is over, you can fully enjoy a peaceful beach holiday.

Why March is better for a beach holiday than other months

According to Climates to Travel, the weather and heat compare like this:

March combines calm water and a warm sea with heat that is still manageable. It also falls outside the big holidays: Tet is over, and the summer rush and the 30 April–1 May holiday have not started yet, so prices and crowds are both easy-going.

Nha Trang snorkelling in March

March is the start of prime snorkelling season. Whale Island Resort names roughly March to September as the favourable period for coral snorkelling around Hon Ong, when the water is calmer and visibility is better (according to the resort’s Nha Trang weather guide).

At this time of year, light winds keep the sea flat in the morning, ideal for children and people who aren’t confident swimmers. The water is around 26–27°C, so most adults can stay in for an hour without a wetsuit.

Where to snorkel? Hon Ong and some of the islands in Nha Trang Bay are beautiful snorkelling spots well worth trying. If you want to explore a colourful coral ecosystem with more than 1,600 species, close to shore, look for a resort with a house reef in Vietnam.

Nha Trang diving in March

• Dive season around Whale Island usually runs from late February to October, so March is early in the main season.
• Another dive guide also says Nha Trang and Whale Island are best for diving from about March to October, when the sea is calmest and visibility is best.
• March is a great month for an Open Water course: calm sea, few crowds and warm water.

A chance to see Whale Sharks in March

According to Whale Island Resort’s whale shark season guide, whale sharks are usually seen in Van Phong Bay from February to May, most often in March and April when the sea is calm. These are wild animals, so a sighting is never guaranteed. To learn more about rare marine life, read our whale watching in Vietnam guide.

What to do in Nha Trang in March

1. Snorkel or dive every day you can: March brings sunshine and fairly calm, clear water, perfect for exploring colourful coral reefs and ocean life. This is the most exciting experience for anyone who loves the sea.
2. Island boat trips: Calm seas and light winds make boat journeys more comfortable, with less rocking. You can explore beautiful islands, swim and enjoy nature together as a family.
3. Kayak and paddleboard: March mornings usually have light winds and still water, ideal for kayaking or stand-up paddleboarding. Gliding over clear blue water and seeing the coast from a different angle is a relaxing experience you won’t forget.
4. Sunrise on Hon Ong: The giant natural granite boulders of Hon Da Lon, the highest point on the island and close to its easternmost tip, are the perfect place to catch the first light of the day. Watching the bay turn golden at sunrise is a favourite with photographers.
5. Mud baths: After a morning in the water, a mud bath is the ideal way to unwind. It feels great and is one of the body-care experiences visitors love most in Nha Trang.
6. Seafood evenings: March evenings are warm, perfect for exploring local food, from steamed snails, crab and grilled squid to all kinds of live seafood. Whale Island Resort serves fresh seafood on the island, while the beachside eateries in town bring a lively atmosphere and flavours you shouldn’t miss.

What to see in Nha Trang in March

• Po Nagar Cham Towers: An ancient Cham complex on a hill overlooking the Cai River. March is sunny, so visit early in the morning to explore, take photos and learn about Cham culture without walking in the harsh midday sun.
• Long Son Pagoda: Famous for its majestic white Buddha statue on the hilltop. A good stop if you want a peaceful space, a stroll and a panoramic view over the city.
• Nha Trang Cathedral (the Stone Church): A Gothic stone building that stands out in the city centre. Its stained-glass windows, tall bell tower and old-world feel make it a favourite photo spot.
• National Oceanographic Museum: Home to thousands of marine specimens, ocean-life collections and rare exhibits. A fun visit, especially for families with young children or anyone who wants to learn about the marine ecosystem before going snorkelling.
• Dam Market: A well-known market full of local specialties such as candied squid, dried fish, bird’s nest, mango cake and dried seafood. Combine sightseeing and tasting, and pick up gifts with the taste of Nha Trang for friends and family.

Tips for visiting Nha Trang in March

• Sun protection: Use reef-safe sunscreen, a hat and a long-sleeved rash vest, as the sun is very strong.
• Book early: Nha Trang resorts often fill up quickly in March and April, so book 1–2 months ahead.
• Getting there: Flights from Ho Chi Minh City to Cam Ranh take about 1 hour 10 minutes on schedule. From Da Lat you can come by road; see how to travel from Dalat to Nha Trang.

After exploring the city and enjoying the activities above, you can slow down on an island that is entering its best coral season.

Whale Island Resort: Snorkelling close to the shore

If your March trip is about the sea, Whale Island Resort is made for exactly that.

Location

The resort is on Hon Ong, a roughly 40-hectare island in the middle of Van Phong Bay, Khanh Hoa, about 95–100 km north of Nha Trang. Travel by car for about 1 hour 30 minutes to North Van Phong port (Dam Mon village), then take the resort boat for roughly 15 minutes. See how to get to Whale Island Resort for private cars and parking.

Seclusion

The island has no permanent residents, no cars, no motorbikes and no bicycles. Whale Island Resort is the only place to stay, and drones and loud speakers are not allowed. The only sounds are the waves and the birds.

Bungalows and room types

The resort has 31 bungalows in 6 room types, 14 of them facing the sea. They are low, palm-thatched buildings of wood, bamboo, rattan and stone with Cham-inspired details, under tropical almond trees. See all room types on the accommodation page of our website.

Highlights on Whale Island

Van Phong Bay is sheltered by mountains, so the water is usually calm with little current. Snorkelling suits all ages: float on the surface or dive about 1 m down, with mask, snorkel and life jacket provided. Scuba runs at around 3–6 m for beginners and 10–15 m for certified divers, with full equipment and professional instructors. The resort also offers a private-island diving package.

Exciting active sea sports

• Windsurfing: Learn or practise with the resort team; see windsurfing at Whale Island (kitesurfing is not offered on the island).
• Kayaking and stand-up paddleboarding on calm March mornings
• Trekking to Hon Da Lon, the island’s highest point, for sunrise over the bay
• Morning yoga, massage and evening films after a day in the water

Sustainability philosophy

Whale Island Resort follows a model of hospitality closely tied to nature and the local community. Since welcoming its first guests in 1994, the resort has always focused on protecting the island and marine ecosystem. About 95% of the team are local people, and day-to-day operations prioritise solar power and micro-hydropower while keeping single-use plastics to a minimum.

As well as weekly beach clean-ups by the resort team, glass bottles are recycled into decorations. Through its partnership with Rainbow Divers and the PADI AWARE Foundation, the resort also supports coral reef restoration with concrete structures and recycled glass bottles that give young coral a surface to grow on.
