Nha Trang is one of the few Vietnamese resorts where the rainy season is short and shifted into autumn. But pick the wrong month, and you could end up in a typhoon instead of on the beach.

It's a familiar story: you spot a cheap package to Nha Trang in November, the price is tempting, and last year's reviews say "everything was great." You book, you fly in, and there's a storm on the coast, waves crashing over the promenade, and instead of the sea you spend three days stuck in your hotel.

November in Nha Trang is a roulette wheel with high stakes. Yet just a couple of months later, it's sunshine, calm seas and those picture-postcard views. The question is when exactly the weather switches, and how far you can trust the calendar.

Why Nha Trang Is "Rainy" at a Different Time From the Rest of Vietnam

Nha Trang lies on the central coast of Vietnam, and its climate differs from that of the southern resorts, Phu Quoc and Ho Chi Minh City. While the south has its rainy season from May to November, in Nha Trang it's shifted into autumn: the main downpours come from September to December, and October and November alone account for about half the annual rainfall.

The reason is the northeast monsoon, which carries moisture from the South China Sea straight onto the central coast. Southern Vietnam is already dry by then, but Nha Trang is still catching the rain. From January to August, on the other hand, the weather here is mostly dry and warm, and it's sunny for most of the year.

The Rainy Season Month by Month

The number of rainy days varies noticeably between climate reference sources, so the ranges below are approximate.

September marks the start of the wet season. There are roughly six to ten rainy days in the month, and daytime temperatures are around 31°C. The sea is still very warm, up to 29°C. The rain usually comes in short evening showers, but the sea can already get rough.

October is when the season gathers strength. There are 12–15 or more rainy days, and the rain is heavier. Temperatures drop to 29–30°C. This is the month when the typhoon risk rises: October and November are the peak of the typhoon season on the central coast.

November is the most unpredictable month. It gets the most rain, between 270 and 330 mm according to various sources (and more in some years). There are 12–15 or more rainy days, and the downpours can be long and violent.

In November 2017, Typhoon Damrey slammed into Khanh Hoa province and caused serious damage in Nha Trang. And in November 2025, the city saw its heaviest rainfall in decades: parts of Nha Trang ended up almost a metre under water, and the Dinh River broke its 1986 record.

December is a transition month. Officially it's still the "rainy season," with around 180–230 mm of rain and about ten rainy days. But in the second half of December, things change noticeably: the showers become rarer and shorter, and the sea calms down. By New Year, the weather is usually fit for a beach holiday, although the odd downpour is still possible.

When the Rain Really Stops

If we're talking about reliably dry weather, it sets in in January. There are three to six rainy days a month, the average air temperature is around 26°C (up to 27–28°C during the day) and the water is 24–25°C. The skies are mostly clear, the wind moderate and the sea fairly calm.

February is drier still, with almost no rain. The air warms to 27°C and the water to 25°C. Weather-wise, it's one of the best months for a beach holiday: comfortable and not too hot.

From March, the weather turns fully summery. Temperatures climb to 29°C by day, with the water at 26°C. April is one of the driest months of the year, with the air at 31°C and the water at 28°C. After that, from May to August, it's hot (up to 32°C), the sea is warm (28–29°C) and there's little rain.

Typhoons: The Main Risk in October and November

A typhoon isn't just heavy rain. It means hurricane-force winds, storm waves, flooded streets and cancelled flights. Vietnam's central coast lies in the South China Sea typhoon zone, and the window of greatest risk runs from mid-October to the end of November.

Nha Trang sits in a sheltered bay, and direct typhoon strikes are noticeably rarer here than in Da Nang or Hue. But the odds are still high enough to treat these months with caution.

Even when a typhoon passes by, its "tail" brings several days of non-stop rain and rough seas, and swimming is banned on those days.

When to Book Your Trip

The answer depends on what you want from the trip.

  • Dry weather and the warmest sea — March–August

There's minimal rain, and the sea is calm and warm. The hottest months are May to July (air at 32°C, water at 28–29°C); the most comfortable temperatures come in March–April and August. Vietnamese holidaymakers head to Nha Trang in summer too: in July, during the school holidays, the resort gets crowded.

  • Dry and not too hot — January–February

There's practically no rain, and the sea has already calmed down. But bear in mind that for Russian travellers this is high season: packages and flights in January are among the most expensive of the year, and hotels are full. Another catch is the water, at 24–25°C, which is cool for the tropics but perfectly comfortable for a Russian traveller.

  • Risky — the second half of December

The rain is easing off but hasn't gone completely. New Year packages here are popular, and the weather usually lives up to expectations, but there are no guarantees: one year it's sunshine and calm seas, another, two days of downpours. Don't expect bargains either: prices peak over the New Year.

  • Better not to risk it — October–November

However tempting the price, this is the peak of the rainy and typhoon season. Even if you're lucky with the weather, the sea will most likely be murky and rough.

What to Keep in Mind When Booking

  • Keep an eye on typhoon forecasts

Vietnam's national weather centre issues warnings several days in advance. If you're flying between October and December, check the forecast before you leave.

  • Don't pay extra for the seafront in the rainy season

A sea view and a beach on your doorstep lose their appeal when the sea is stormy: seafront hotels take the full force of the wind and spray. It matters more that your hotel has a pool, which isn't a luxury but a back-up plan for when the beach is closed.

  • Get insurance that covers natural disasters and flight delays

If your flight is cancelled because of a typhoon, a standard package may not cover the cost of extra hotel nights.

  • Don't rely on averages alone

"Three rainy days a month" is an average over many years. A particular January may be perfectly dry, or it may bring a week of grey skies. In the tropics, it's always a probability, not a timetable.
