Nha Trang weather at a glance

Daily temperatures sit between 21°C (70°F) and 33°C (91°F) across the year, so there is no cold season. Humidity averages about 80%, which makes 28-33°C (82-91°F) feel hotter than the number suggests. A sea breeze keeps the coast less harsh than northern cities such as Hanoi. Current conditions change by the hour, so check the national hydro-meteorological forecast before you pack.

• Coolest month: January, with average lows near 21°C (70°F).
• Driest month: February, with about 16 mm of rain.

Dry season vs. rainy season in Nha Trang

Nha Trang runs on two seasons. The dry season lasts from January to August, with warm, humid days and little rain. Average temperatures run 28-30°C (82-86°F), which suits swimming, snorkelling and island trips. July and August are the hottest months, and domestic school holidays from June to August fill the beach and tighten hotel supply. The rainy season runs from September to mid-December. September records about 133 mm, October 269 mm, November 295 mm and December 178 mm. Thunderstorms and typhoons can interrupt plans. Our rainy season guide covers month-by-month detail.

Best time to visit Nha Trang, by traveler type

February to late April is the best all-round window. Days are sunny and mild, and sea and sightseeing both work. Divers should aim for April to August, when water is reported to be clearest around the coral sites. Budget travelers can take the rainy months. As a rough yardstick, treat a July room quote of ₫1,500,000 as your benchmark. A rainy-season rate well under ₫1,000,000 is the discount worth the storm risk. Rates vary by hotel, so compare live prices. Our best time to visit guide weighs these trade-offs in full. Winter-sun seekers can read about Nha Trang in January: Weather, Costs & What to Do.

• Beach and swimming: February to April.
• Diving and snorkelling: April to August.
• Lowest prices: October and November, with storm risk.
• Fewer crowds: avoid June to August and public holidays.

What to do in Nha Trang when it rains

Rain rarely lasts all day outside the wettest weeks. Plan indoor or covered stops for downpours. The Po Nagar Cham Towers work well in a drier morning gap. Cafés along the beach promenade suit the afternoon showers. The Vinpearl cable car depends on wind and lightning, so keep it flexible. Hon Mun Island snorkelling is the first thing to go in rough seas. Never book it on your only free day in October or November. Mistake to avoid: stacking an island-hopping tour on a single fixed date in the wettest months.

Storms, sea conditions and booking flexibility

Late-year storms bring rough seas, and boats can be cancelled at short notice. Visibility underwater drops after heavy rain. Watch national storm warnings in the days before travel. Book refundable rooms from September to mid-December. Buy travel insurance that covers weather disruption and flight changes. Heavy rain can also disrupt roads and flights into the Khanh Hoa coast, so leave a buffer day before an international departure.

What to pack for Nha Trang weather

Light, quick-dry clothing works all year. UV stays high even under cloud, so pack reef-safe sunscreen, a hat and sunglasses. In September to December, add a light rain jacket, waterproof phone pouch and sandals with grip. In January, bring a thin layer for breezy evenings near 21°C (70°F).

• All year: sunscreen, hat, swimwear, insect repellent.
• Rainy season: rain jacket, dry bag, spare shoes.
• Dive months: rash guard and your own mask if you prefer a fit.
