Overview of Nha Trang’s December Climate
December in Nha Trang means cooler, drier weather compared to the months before. You’ll notice mild temperatures, moderate humidity, light but frequent showers, and long daylight hours for exploring.
Temperature Ranges During Christmas
Nha Trang’s December weather feels mild and comfortable. Daytime highs usually land between 25°C and 28°C (77°F–82°F), and nights drop to about 21°C to 23°C (70°F–73°F).
It’s cooler than summer, but still warm enough for swimming or hanging out on the beach.
Early December starts off around 26°C, then dips a bit to about 25°C by month’s end. Evenings can feel a little cooler, so tossing a light sweater or long-sleeve shirt in your bag isn’t a bad idea if you’ll be out at night.
This steady temperature range makes December a great time to explore the city, relax on the sand, or take a day trip out to the islands.
Humidity Levels in December
Humidity in December usually sits around 80%–85%. That’s high compared to some other coastal spots, but it’s lower than during the rainiest season.
You might notice a sticky feeling during the day, especially if you’re walking or biking around.
The mornings and evenings often feel fresher, thanks to cooler temps. Rain can make things muggy for a bit, but showers don’t stick around long.
Compared to November, December’s air feels a touch drier, so sightseeing and outdoor dining feel more comfortable.
If you’re sensitive to humidity, you can stick to indoor activities in the hottest part of the day. Hotels, cafes, and shopping centers usually have air conditioning, which helps a lot.
Sunshine Hours and Daylight
Nha Trang gets plenty of sun in December. You’ll typically see 8 to 9 hours of sunshine a day, and total daylight lasts 11 to 11.5 hours.
That’s more than enough time for the beach, markets, or boat trips.
The sun rises around 6:00 AM and sets close to 5:30 PM, so evenings come earlier than in summer.
If you plan outdoor stuff, it’s best to do it earlier in the day to catch the most daylight.
Clouds come and go, but even with a quick shower, you’ll often spot breaks of sunshine. These bright spells make the coastline and islands look especially inviting during the holidays.
Typical Weather Patterns Near Christmas
By late December, the rainy season is winding down in Nha Trang. Rainfall drops compared to November, averaging 90–120 mm for the month.
Rain usually falls in short bursts, not all-day storms. You’ll get 9 to 14 wet days this month.
Winds stay light to moderate, which keeps the sea calmer than earlier in the year. That’s good news if you’re hoping to book a boat tour, go snorkeling, or dive.
Cloudy days still happen, but overall, the weather feels more stable. The combo of mild temps, less rain, and longer days makes it easy to relax on the beach or explore the city.
Rainfall and Precipitation Around Christmas
December weather in Nha Trang still shows some wet season traits, but the rain isn’t as heavy as in October or November. You’ll get a mix of heavy showers and dry spells, and things get drier as the month goes on.
Average Rainfall in December
Rainfall averages around 250–280 mm for December. That’s still a lot compared to the dry season, but it’s less than the peak rainfall earlier in autumn.
Showers usually come in short, heavy bursts, not long, gloomy days.
Most rain falls in the afternoon or evening, so you’ll often have dry periods too.
Humidity stays up, often near 75–85%, which can make the air feel warmer than the thermometer says. Even when the rain’s heavy, it tends to clear up fast, so you can get back outside.
December sits between October’s super wet weather and January’s much drier conditions.
Frequency of Rainy Days
You’ll probably see 8–13 rainy days in December, though it varies year to year. So, about a third of the month brings some rain.
But a rainy day doesn’t mean it pours all day—often it’s just a burst, then the sky clears up.
This pattern lets you fit in beach trips or sightseeing during the dry stretches.
The chance of rain on any day is about 25–30%, which is down from November but higher than January.
Storms can still pop up, so carrying a light rain jacket or poncho makes sense. Keeping your plans flexible helps you enjoy both sunny and wet spells.
Transition From Rainy to Dry Season
December marks the move from wet to dry season in Nha Trang. Showers still happen, but they’re less frequent and intense as the month goes on.
By late December, rainfall drops, and you’ll see more clear days. This trend continues into January, when dry, sunny weather takes over.
The sea holds steady at about 26°C, so swimming and water sports stay comfortable even with a few showers.
You’ll probably notice more people at the beach or out and about as the weather improves.
This transition period brings cooler air, less rain, and more sunshine—a nice balance for visitors.
Water Temperature and Beach Conditions
The sea in Nha Trang stays warm in December, though it’s a bit cooler than earlier in the year. Swimming is still comfortable, but conditions can shift with wind, rain, and seasonal changes.
Sea Temperature for Swimming
December’s average sea temperature is about 24–25°C (75–77°F). It’s a tad cooler than November, but most people will find it just fine for swimming—no wetsuit needed.
The water feels refreshing after time in the sun. If you’re sensitive to cooler water, you might notice the difference from summer, but it’s still good for a long swim.
Nha Trang’s tropical climate keeps the sea from dropping below 23°C (73°F) at this time. You can count on warm water, even with some clouds.
Suitability for Water Activities
You can usually snorkel, boat, or swim without trouble in December. The sea’s a bit cooler but still comfortable for most water sports.
December’s a transition month, so you might run into some rain or stronger winds. That can affect snorkeling visibility or make the waves choppier.
If you’re into surfing or kiteboarding, seasonal winds could work in your favor. For calmer stuff like paddleboarding or kayaking, mornings are usually your best bet.
With moderate sea temps and manageable weather, you’ve got lots of options for beach fun—just keep an eye on the daily forecast.
Comparing Nha Trang’s Christmas Weather to Other Destinations
Nha Trang stays warm and fairly dry around Christmas, which sets it apart from other parts of Vietnam. You’ll get good beach weather here, while cities up north can feel chilly and damp.
Weather Differences With Hanoi and Other Vietnamese Cities
In Hanoi, December days usually sit between 15–20°C (59–68°F). Nights feel colder, and the air often gets damp from mist or light rain.
That can make sightseeing less appealing, especially if you’re not a fan of cool, humid air.
Nha Trang averages 23–28°C (73–82°F) with less humidity. The skies clear up, and rain gets lighter as December brings the start of dry season.
You can still swim in the sea, which stays warm for water activities.
Da Nang and Hoi An fall somewhere in the middle. They’re cooler than Nha Trang, with temps around 18–24°C (64–75°F) and more rain.
Ho Chi Minh City is hot and dry in December, with highs near 30–32°C (86–90°F)—maybe a bit much for some travelers.
| Destination | Avg. Temp (°C) | Rainfall | Comfort Level |
|---|---|---|---|
| Hanoi | 15–20 | Light rain, mist | Cool, damp |
| Da Nang/Hoi An | 18–24 | Moderate showers | Mild, variable |
| Nha Trang | 23–28 | Low rainfall | Warm, pleasant |
| Ho Chi Minh City | 30–32 | Very dry | Hot, sunny |
Why Choose Nha Trang for a Christmas Holiday
If you want warm weather without overwhelming humidity, Nha Trang offers one of the best December climates in Vietnam.
You can hit the beach without the heavy rain of central Vietnam or the cold, damp air up north.
The sea stays comfortable, so swimming, snorkeling, or diving is easy. Evenings cool off but never get cold, so just bring light layers.
Unlike Ho Chi Minh City, which can get uncomfortably hot, Nha Trang’s climate feels more relaxed. That makes walking around, visiting temples, or shopping at markets a lot more enjoyable.
Tourist numbers go up during Christmas, but things stay chill compared to bigger cities. Hotels and restaurants often add a festive touch, so you get a holiday vibe with tropical weather.
This mix of beach-friendly warmth, lower humidity, and seasonal celebrations makes Nha Trang a smart pick for a Christmas getaway.
What to Pack and Expect for Christmas in Nha Trang
December in Nha Trang brings mild daytime warmth, cooler evenings, and less humidity than the wet months. You can enjoy the beach, holiday events, and city life with the right mix of light, practical clothes and a bit of planning for the festive season.
Recommended Clothing for December Weather
Daytime temps usually run 23°C to 28°C (73°F to 82°F). The sun can be strong, so pack light cotton shirts, shorts, and breathable dresses.
A wide-brimmed hat and sunscreen go a long way, especially midday.
Evenings cool down to around 21°C (70°F). Bring a light jacket or sweater for walks on the beach or outdoor dinners.
You won’t need heavy winter gear, but layers help if you’re out late.
For water activities like snorkeling or island tours, grab a swimwear set and quick-dry clothes. Some people like a thin rash guard for extra sun protection in the water.
Here’s a simple packing list:

|---|---|
| Light shirts & shorts | Daytime comfort |
| Light jacket/sweater | Cooler evenings |
| Swimwear | Beach & water sports |

Travel Tips for the Holiday Season
Christmas and New Year always pull more visitors into Nha Trang. If you want to avoid paying too much or missing out, book hotels and tours early.
Many resorts and restaurants put together special holiday menus and events. Check their schedules ahead of time—spots sometimes fill up before you know it.
Try outdoor activities like island hopping or diving in the morning. The weather feels calmer, and crowds haven’t shown up yet.
By afternoon, it usually gets warmer, and attractions start to feel packed. You might want to plan your sightseeing around that.
Keep a bottle of water with you, especially if you’re out for hours. I’d toss sunscreen and insect repellent in your bag too—those little things make a big difference.
December markets buzz with energy and offer loads of fresh seafood and festive snacks. If you’re shopping, bring cash in smaller bills since not every stall takes cards.
Annual Weather Trends and Best Times to Visit
Nha Trang sits in a tropical climate, so you’ll get warm temperatures all year. Rainfall and humidity swing a lot depending on the season.
You’ll spot clear differences between the dry months at the start of the year and the wetter conditions that roll in during autumn.
How December Compares to Other Months
December brings average temperatures between 22–27 °C (72–81 °F). The air feels warm, but not stifling like it does in the summer.
Nights can drop to the low 20s °C, which feels cooler than most other months. I think it’s a nice break from the usual heat.
Rain sticks around in December, with about 155 mm spread across 14 days. That’s less than the heavy downpours of October or November, which often go past 300 mm.
Humidity usually stays above 75%. Thanks to the cooler air, it’s not as uncomfortable as the sticky stretch from May through August.
You’ll only get about 4–5 hours of sunshine per day—a far cry from the 8–9 hours you see in spring. That can be a bit disappointing if you’re craving sun.
The sea keeps warm at roughly 26 °C, so swimming still feels great, even if it’s raining. But storms and rougher seas show up more often in December than earlier in the year.
Insights for Planning Future Visits
If you want dry, sunny weather, try to visit between February and April. Rainfall drops to its lowest, and daily highs usually sit around 26–28 °C. These months work well for sightseeing or beach days. Diving? This is probably the best time.
May to August gets hotter, with highs over 32 °C. You’ll still see little rain, but the humidity cranks up and makes outdoor stuff a bit sticky. Maybe stick to mornings or evenings if you want to get out and explore.
September to November brings heavy rains and the occasional tropical storm. Storms can disrupt travel plans, and keeping outdoor activities on track might be tough.
December sits somewhere in the middle. You’ll notice cooler air and warm seas, but there’s still some rain. If you don’t mind a few showers and like smaller crowds, December could be a pretty good pick.
