If you’re planning a trip to Nha Trang in the fall, you’ll want to be ready for warm days and some pretty unpredictable skies. Daytime highs usually sit around 27–30 °C (81–86 °F), and nights stay mild, but this is also when the heaviest rainfall of the year kicks in. The shift from dry to wet weather really changes the vibe, making fall a surprisingly lively time to visit this coastal city.
From September to November, the northeast monsoon rolls in with frequent showers and the occasional storm. Still, you’ll catch periods of sunshine breaking through. The sea stays warm enough for swimming, though waves sometimes get a bit wild during storms.
These ups and downs define fall in Nha Trang, giving you a mix of dramatic weather and chances to hit the beach whenever the skies open up.
If you know what to expect, you can make smarter plans. You’ll notice how temperatures change month to month, when the rain is at its worst, and how humidity, clouds, and wind shape daily life.
With a bit of planning, fall in Nha Trang can be pleasant and memorable, whether you’re wandering the coast or just relaxing by the water.
Overview of Fall Weather in Nha Trang
Fall in Nha Trang brings high humidity, frequent rainfall, and shifting winds as the wet season takes over. You’ll feel warm temperatures, see cloudy skies, and notice rougher seas compared to the calmer, drier months earlier in the year.
Typical Fall Climate Patterns
Daily high temperatures in Nha Trang drop a bit, starting at about 89°F (32°C) in early September and cooling down to around 82°F (28°C) by late November. Nights cool too, from 79°F (26°C) to 74°F (23°C).
The air stays humid and muggy nearly all the time.
Rainfall ramps up fast in the fall. October usually stands out as the wettest month, with close to 240 mm (9.5 inches) of rain.
You’ll see the highest chance of a wet day in early October—over 50%—and then it drops a bit by late November. Most rain falls in heavy, sudden bursts, not gentle sprinkles.
Clouds stick around, with skies often overcast or mostly cloudy. Winds pick up too, climbing from about 7 mph in September to nearly 15 mph by November.
As the monsoon pattern shifts, the wind direction changes from south to north.
Comparison to Other Seasons
Compared to spring and summer, fall in Nha Trang feels wetter and gloomier. The dry season, running January through August, brings clearer skies, calmer seas, and much less rain—often under 50 mm (2 inches) a month.
Fall months dump several times that amount.
Temperatures stay warm all year, but you’ll feel a drop from summer highs of 90°F (32°C) to fall averages near 82°F (28°C). Still, the humidity and frequent storms can make things less comfortable.
When you look at winter, you’ll see rainfall peaks in fall and tapers off by January. Winter is drier and sunnier, though still warm.
For reliable beach weather, spring or early summer is your best bet. Fall brings more surprises with heavy rain and stronger winds.
Average Temperature Trends in Fall
As fall rolls on in Nha Trang, temperatures gradually slide downward. You’ll still get warm days, but the intense summer heat fades, and you’ll notice bigger differences between day and night.
Daily Highs and Lows
Highs in Nha Trang start around 89°F (32°C) in early September and dip to about 82°F (28°C) by late November. Lows cool off too, from 79°F (26°C) down to 74°F (23°C).
So, you’ll still feel warmth, but it won’t be as stifling as in summer. Nights stay mild—rarely dropping below 71°F (22°C)—so heavy jackets aren’t really necessary.
The hottest part of the year usually brings highs close to 90°F (32°C), while the coolest winter days average nearer 71°F (22°C). Fall fits comfortably in the middle.
| Month | Avg High | Avg Low |
|---|---|---|
| September | ~89°F (32°C) | ~79°F (26°C) |
| October | ~85°F (29°C) | ~76°F (24°C) |
| November | ~82°F (28°C) | ~74°F (23°C) |
This steady cooling makes fall pretty good for outdoor plans, though humidity and rain still matter.
Hourly Temperature Variations
If you check hourly data, you’ll see midday temps hover near 85°F (29°C) in September, dropping to about 80°F (27°C) by November.
Evenings cool down more slowly, often staying above 75°F (24°C) until late. Since dew points stay high, nights feel humid and muggy, even as temps fall a bit.
You’ll probably notice the biggest difference between early mornings and mid-afternoons. Mornings might start at 74–76°F (23–24°C), then climb 8–10 degrees by early afternoon.
This means mornings and late afternoons are sweet spots for the beach or outdoor adventures. The weather’s pretty predictable in terms of these daily shifts.
Rainfall and Precipitation Patterns
Rainfall in Nha Trang during fall climbs from moderate in September to really heavy by November. Both total rainfall and the number of rainy days go up as the season moves along.
Monthly Rainfall Amounts
September usually brings about 170 mm of rain spread out over more than two weeks. Rain comes often, but you’ll still get dry, sunny days, so you can squeeze in outdoor plans if you’re flexible.
By October, the rain steps up a notch. Average precipitation hits around 240 mm, and storms get more intense.
November is the wettest month of fall. You might see up to 330 mm of rain, with damp conditions sticking around. Rain tends to come in bursts, and flooding in lower areas can happen.
| Month | Avg. Rainfall (mm) | Rainy Days (approx.) |
|---|---|---|
| September | ~170 | 18 |
| October | ~240 | 20 |
| November | ~330 | 12 |
Probability of Wet Days
As fall goes on, the odds of a wet day in Nha Trang get higher. In September, rain falls on over half the days. Showers are usually short but frequent enough to mess with your outdoor plans.
October brings an even bigger chance of rain. The probability of wet weather stays above two-thirds of the month, with longer and heavier downpours.
In November, the rain gets more concentrated. There might be fewer rainy days than October, but when it rains, it really pours. So, you’ll want to be ready for very wet conditions, even if the calendar shows fewer rainy days.
Humidity and Dew Point Levels
In fall, Nha Trang hits you with high humidity and steady dew points, making the air feel heavy. These factors can really affect how comfortable you feel, especially when it’s warm.
Average Humidity in Fall
Humidity stays high all fall. From September to November, average relative humidity sits between 81% and 84%, with October and November often topping out for the year.
You’ll notice the air feels moist, especially in the mornings and evenings. Rainy days push the humidity even higher, making things sticky and less pleasant for outdoor fun.
Humidity almost never drops below 78% in this area, even in the drier months. In fall, the combo of high humidity and temps around 27–30°C (81–86°F) makes it feel warmer than it really is.
If you’re planning to be outside, especially near the water, expect it to feel muggy. Light clothes, shade, and plenty of water help a lot.
Dew Point Fluctuations
The dew point tells you just how humid it feels. In fall, dew points in Nha Trang usually stick in the 23–25°C (73–77°F) range, which is definitely on the humid side.
These numbers barely change from September to November, shifting only a little with rainfall and wind. When the dew point stays above 24°C, the air feels pretty oppressive, especially around midday.
At night, dew points stay high, so it doesn’t cool off as much as you might hope. Evenings can feel warm and damp, even when the temperature drops.
Travelers often find that rooms without air conditioning feel clammy because of the high dew point. Picking places with good ventilation or AC can really help you feel more comfortable.
Cloud Cover and Sunshine Hours
In Nha Trang, fall weather starts off with lots of clouds and gradually shifts toward clearer skies, even as daylight hours get shorter. This affects how much sunshine you’ll actually get, which matters if you’re hoping for beach time.
Cloudiness Trends
Cloud cover in Nha Trang drops steadily throughout fall. Early in the season, skies are overcast or mostly cloudy about 95% of the time, but by late November, that falls to around 73%.
You’ll still see mostly cloudy days, but clear skies become more common as fall goes on. The clearest day usually lands near the end of November, when there’s about a 27% chance of clear or partly cloudy skies.
For reference, the cloudiest time of year is early June, when the sky is almost always gray. In fall, things slowly improve, so you’ll get a few more breaks of sunshine.
If you’re into sightseeing or photography, these patterns matter since the light changes fast. A mix of clouds and sun can also play tricks on how warm it feels, even if the temperature doesn’t change much.
Daylight Duration
Days get shorter in Nha Trang as fall moves along. Early September gives you about 12 hours and 21 minutes of daylight, but by late November, you’re down to 11 hours and 28 minutes.
Sunrise gets later, from around 5:32 AM in late September to 5:47 AM at the end of November. Sunsets come earlier too, shifting from almost 5:53 PM at the start of September to about 5:14 PM by mid-November.
This means less time for evening activities as fall goes on. If you’re planning trips or boat rides, it’s smart to start earlier in the day to catch more sunlight.
While days are shorter, actual sunshine hours depend more on cloud cover. Even with less daylight, breaks in the clouds can give you bright, sunny moments that feel longer than the clock says.
Wind Speed and Atmospheric Conditions
In fall, Nha Trang gets steady coastal winds and moderate pressure, shaping the weather you’ll feel outside. These conditions matter for stuff like boating, swimming, and sightseeing.
Typical Wind Patterns
Expect light to moderate breezes along the coast during fall. Average wind speeds usually sit between 10–15 km/h (6–9 mph), but you might get stronger gusts when seasonal rains hit from September to November.
Most winds blow from the northeast as the monsoon pattern shifts. This brings slightly cooler air and more clouds compared to summer. By late November, winds can feel stronger and more steady, especially on open beaches.
You’ll still get calm days, but short bursts of stronger wind often come with afternoon showers. If you want to avoid the breeze, early mornings are usually calmer, while afternoons pick up.
| Month | Average Wind Speed | Common Direction |
|---|---|---|
| September | 12 km/h | Northeast |
| October | 13 km/h | Northeast |
| November | 14 km/h | Northeast |
Influence of Elevation
Nha Trang sits close to sea level, and honestly, you won’t see much change in elevation across the city. Wind speed and pressure usually stay pretty steady almost everywhere.
You probably won’t notice any big differences between the beach and the city center.
The hills and mountains around the city shape how the air moves. These natural barriers block some of the wind inland, but along the open coast, gusts can pick up and feel stronger.
In the fall, atmospheric pressure tends to stay moderate, and you’ll just see minor shifts each day. The low elevation means you’re not likely to get those sudden pressure changes that happen in high-altitude spots.
This makes the weather feel more settled, even if a rain shower rolls through.
If you head inland toward higher ground, you might find cooler air and less wind than you’d get by the water. That contrast comes in handy when you’re planning a day trip away from the coast.
Travel Tips for Visiting Nha Trang in Fall
Rain shows up more often in fall, but the temperatures stay warm and honestly, pretty comfortable. You can still hit the beaches, check out cultural sites, and sample some great local food. Planning around the rainier days helps you squeeze more out of your trip.
Best Activities and Destinations
During fall, Nha Trang moves into its wet season, which usually runs from September to mid-December. You’ll get short, heavy downpours, but the sun still comes out plenty.
The sea can get rough, so water activities like snorkeling or diving might be off the table sometimes.
Instead, you could check out cultural or indoor spots. Long Son Pagoda, with that giant white Buddha, is a must-see. The National Oceanographic Museum lets you get up close with regional marine life.
Markets like Dam Market are fun for wandering and trying new food, plus you stay dry under the roof. If the rain lets up, head to Hon Chong Promontory for the views, or maybe take the cable car out to Hon Tre Island and spend the day at VinWonders.
When you’re planning your days, try to keep things flexible. Mornings tend to have lighter rain, so it’s a good time to get outside. Carrying a light raincoat or an umbrella makes city exploring way easier.
Resorts and Accommodation Advice
Fall counts as a shoulder season in Nha Trang, so you’ll often find resorts and hotels lowering their rates compared to the dry months. This means you can try out fancier places without breaking the bank.
Beachfront resorts like Vinpearl Nha Trang on Hon Tre Island offer pools, spas, and restaurants, which come in handy when it rains. If you pick a place with good indoor amenities, you’ll always have something to do, even if the weather turns.
If you’d rather stay in the city, hotels near Tran Phu Street put you close to both the beach and local eats. It’s still smart to book ahead, since weekends and holidays can get busier.
Try to find places with shuttle services or easy taxi access, because sudden rain makes walking less appealing. Picking a hotel with a restaurant on-site also saves you from going out when it’s stormy.
Regional Weather Context
Nha Trang’s fall weather stays warm and humid, with steady sea breezes and a clear rainy season. Compared to northern cities, you’ll notice Nha Trang doesn’t cool off as much, and the rainfall pattern is different.
Comparison with Hanoi and Other Cities
If you travel between Nha Trang and Hanoi in the fall, you’ll spot some pretty clear differences. Nha Trang usually gets highs of 82–89°F (28–32°C), and the air feels muggy. Rain showers pop up often.
Meanwhile, Hanoi cools off faster. Highs hover around 75–85°F (24–29°C), and the evenings can get noticeably chillier.
Rainfall doesn’t follow the same pattern either. Nha Trang sees its heaviest rain in October and November. Hanoi, on the other hand, usually wraps up its wettest months by September.
So, you might run into heavier downpours along the central coast even when the north starts drying out.
When you look at Ho Chi Minh City, Nha Trang comes off as a bit cooler in the fall. Its rainy season doesn’t last as long, but when it rains, it pours.
Central Vietnam’s coastline faces stronger seasonal winds, especially toward late November. Southern areas? They tend to stay much calmer.
If you’re planning a trip, you’ll want to pack for rain in Nha Trang during fall. For Hanoi, maybe bring something for cooler evenings. Down south, expect steadier warmth.
