May is hot, mostly sunny and a good month for the sea in Nha Trang. The long-term average is about 81 mm of rain, mostly in short afternoon storms, and the water is around 29°C and usually calm enough for island trips. After the Labour Day holiday in the first week, the city is quieter than in July and August. My Nha Trang travel guide covers the rest of the year if you’re still choosing a month.
Weather in Nha Trang in May
- Temperature: highs around 32°C (90°F), lows around 25°C (77°F)
- Rainfall: about 81 mm, spread over roughly 15 days with rain, usually as short afternoon storms
- Sea: about 29°C, warm and mostly calm
The heat is the main thing to plan around. Do the beach, islands and Long Son’s steps in the morning, and save covered options like markets and the museum for the early afternoon, when storms are most likely.
Events in May
- Labour Day (1 May): National holiday — combined with Reunification Day on 30 April it creates a long weekend; the beach is at its busiest in early May as a result
Best Things to Do in Nha Trang in May
Nha Trang Beach
May’s warm sea temperature and long daylight hours make the beach an easy choice. The main Tran Phu Beach strip — 6 km of white sand fronted by the Tran Phu boulevard — is at a quieter mid-season pace once the Labour Day holiday passes. Morning swimming is reliably good; afternoon storms pass quickly and the evenings are warm and pleasant. Water sports (jet skiing, parasailing) are available along the beach.

Hon Mun Island & Snorkelling
May is a good month for island tours. The sea is warm and usually calm, and snorkelling around Hon Mun is good on most mornings. Go early in the day, before afternoon storms build. Book an organised tour through a reputable operator rather than leaving it to chance at the pier.

Long Son Pagoda
The 152-step climb is best tackled in the early morning in May before the heat and humidity build. The pagoda grounds are typically less crowded than in peak season, making for a more relaxed visit. The white Buddha statue on the hilltop and the panoramic views are the main draw; the dragon mosaics on the pagoda walls are worth examining up close on the way up.

Nha Trang Night Market
The night market comes into its own in May evenings — after an afternoon shower the air cools and the beach promenade fills with locals and visitors. Fresh grilled squid, steamed clams, and prawn hotpot are the staples; wash it down with a bia hơi (fresh draught beer) from one of the plastic-stool spots nearby. The market is good value and a reliable evening in any month.

Also Worth Doing
- Vinpearl Land: A good rainy-day option — the indoor aquarium, covered rides, and resort facilities make it viable even in wet weather
- Dam Market: Nha Trang’s main local market for fresh produce, dried seafood, and Vietnamese cooking ingredients — far more local than the night market
Practical Tips for May
- Heat strategy: beach and outdoor sights in the morning; markets, the museum or a rest in the early afternoon
- Early May: The Labour Day holiday (1 May) keeps tourist numbers high through the first week — quieter from mid-May onwards
- Prices: Accommodation rates begin to drop from May — good value compared to January–April peak
