These are long-term climate averages rather than a forecast for a particular year. Actual conditions can vary, especially during the rainy season.
January Weather in Vung Tau
January is one of the best months for Vung Tau Weather by Month.
Daytime temperatures are usually around the high 20s Celsius, while nights are comfortable and rainfall is relatively low.
This is a particularly good month for combining beach time with outdoor sightseeing. You can spend the morning at Bãi Sau, walk along the waterfront later in the day and visit attractions such as the lighthouse without having to build your entire itinerary around rain.
Best for: beaches, swimming, walking, sightseeing and photography.
My rating: Excellent.
February Weather in Vung Tau
February is arguably the most reliable month for beach weather.
Long-term climate data shows some of the lowest rainfall of the entire year in February, while daytime temperatures remain around 29°C.
The combination of warmth and very low rainfall makes this an excellent month for swimming, beach walks and outdoor attractions.
If I had complete freedom to choose a month for a Vung Tau beach trip based purely on weather, February would be one of my first choices.
Best for: swimming, beaches, outdoor attractions and long walks.
My rating: Excellent.
March Weather in Vung Tau
March continues the dry and relatively comfortable conditions.
Temperatures rise slightly compared with January and February, with daytime highs around 30°C, but rainfall remains relatively low.
This is another excellent month for a beach holiday, especially if you also want to explore the mountains, lighthouse and other outdoor attractions.
By the middle of the day it can already feel hot, so early morning and late afternoon are generally more comfortable for walking.
Best for: beaches, sightseeing and outdoor activities.
My rating: Excellent.
April Weather in Vung Tau
April is when the heat becomes much more noticeable.
Average daytime highs are around 32°C, making April one of the hottest months of the year. Rainfall is still relatively modest compared with the following months.
This means April can actually be an excellent beach month if you are comfortable with heat.
The main thing I would change is the timing of your activities. Go to the beach in the morning, take a break during the hottest part of the afternoon and return outside later in the day.
UV levels can also be extremely high, so sunscreen, sunglasses and shade are important.
Best for: swimming and beach holidays.
My rating: Very good, especially if you tolerate heat.
May Weather in Vung Tau
May is the transition into the wetter part of the year.
Temperatures remain high, with daytime highs around 32°C, but rainfall increases significantly compared with April.
You can still have excellent beach days, but the weather becomes less predictable.
If you are traveling in May, I would check the short-term forecast before planning a full day around outdoor attractions.
Best for: flexible beach trips and short breaks.
My rating: Good with flexibility.
June Weather in Vung Tau
June is hot, humid and noticeably wetter.
Long-term climate averages put daytime temperatures around 31°C, with rainfall much higher than during the dry season.
Rain can arrive as heavy showers or thunderstorms rather than necessarily lasting throughout the entire day.
This is why I would not automatically cancel a June trip. Instead, leave gaps in your schedule so you can move activities around the weather.
For example, you can visit the beach in the morning and keep museums, cafes and restaurants as backup options if rain arrives later.
Best for: flexible itineraries and travelers who do not mind tropical showers.
My rating: Possible, but weather-dependent.
July Weather in Vung Tau
July is firmly within the rainy season.
Temperatures remain warm, around 31°C during the day, but rainfall is high and wet days become much more frequent.
This is not the month I would choose if your entire trip depends on guaranteed beach weather.
However, Vung Tau still has plenty to do when the weather changes. A rainy afternoon can easily become a museum visit, café stop or long seafood lunch.
Best for: flexible trips rather than beach-only holidays.
My rating: Moderate.
August Weather in Vung Tau
August continues the wet-season pattern.
Daytime temperatures are still around 30°C, but rainfall remains high and cloud cover is more common than during the dry season.
The important thing is that rainy-season statistics do not mean it rains continuously from morning until night. Tropical weather can change quickly, with sunny periods between heavy showers.
If you are staying for several days, this can be perfectly manageable. If you are visiting for one day only, the forecast becomes much more important.
Best for: flexible travelers and longer stays.
My rating: Moderate.
September Weather in Vung Tau
September is one of the wettest months of the year.
Long-term climate data shows very high rainfall during September, while temperatures remain around 30°C during the day.
The sea can still be warm, but the overall reliability of beach conditions is lower than during the dry season.
If you have a choice of dates and your main goal is swimming, I would choose another month.
If September is the only time you can travel, keep your plans flexible and avoid scheduling every day around outdoor activities.
Best for: flexible city breaks and travelers comfortable with rain.
My rating: Less reliable for a beach holiday.
October Weather in Vung Tau
October is another very wet month.
Climate averages show rainfall at one of the highest levels of the year, although temperatures remain warm at around 30°C.
The positive side is that October is still tropical and warm rather than cold and gloomy. The problem is simply that rain can disrupt outdoor plans.
If you are visiting for several days, keep outdoor activities flexible and use the clearer periods of the day when they appear.
Best for: flexible itineraries and longer stays.
My rating: Less reliable for beach-focused trips.
November Weather in Vung Tau
November is a transition month.
Rainfall begins to decrease compared with October, although it can still be significant during the first part of the month.
Temperatures remain warm, with daytime highs around 29°C.
By the end of November, conditions are generally moving toward the much drier pattern of December through April.
This can be a good month if you want warm weather but prefer to avoid the hottest part of the year.
Best for: shoulder-season travel and outdoor sightseeing.
My rating: Good, especially later in the month.
December Weather in Vung Tau
December marks the beginning of the more reliable dry-season period.
Temperatures are comfortable by tropical standards, with daytime highs around 29°C, while rainfall is considerably lower than in October and November.
It is a strong month for beaches, swimming, sightseeing and long walks.
December also starts the busier tourist period, particularly around weekends and holidays, so hotel prices can be higher than during the wet season.
Best for: almost everything outdoors.
My rating: Excellent.
Vung Tau Rainfall by Month
If rain is the main thing you are trying to avoid, the pattern is very clear.
| Month | Approx. monthly rainfall | Rainy days |
|---|---|---|
| January | ~36 mm | ~7 |
| February | ~15 mm | ~5 |
| March | ~28 mm | ~5 |
| April | ~64 mm | ~8 |

| November | ~188 mm | ~14 |

These figures are long-term climate averages and should be used as a planning guide rather than a prediction for a particular trip. Different climate datasets use different observation periods and methods, so exact monthly totals vary between sources.
How Hot Is Vung Tau Throughout the Year?
One of the easiest things about planning Vung Tau is that temperatures do not change dramatically between seasons.
The average daytime maximum is roughly 29–32°C throughout the year.
The hottest period is generally around April and May, while January is among the cooler months.
Even the “cooler” months are still warm enough for the beach.
The bigger difference between January and September is therefore not temperature. It is rainfall.
What Is the Sea Temperature in Vung Tau?
The sea around Vung Tau remains warm throughout the year.
Long-term climate averages put sea temperatures roughly around 28°C for much of the year, with only relatively small seasonal changes.
So if you are deciding whether you can swim, air temperature is usually not the limiting factor.
The more important questions are rainfall, wind, waves and the actual conditions on the day.
Best Months for Vung Tau Beach
If the beach is your main priority, I would rank the months approximately like this:
- February — very dry and warm
- January — dry and comfortable
- March — dry and warmer
- December — dry-season conditions return
- April — excellent beach weather but very hot
- November — improving conditions
May through October can still produce excellent beach days, but the probability of rain is much higher.
Best Months for Outdoor Sightseeing
For attractions such as the Vung Tau Lighthouse, Mũi Nghinh Phong, mountain viewpoints and Hồ Mây Park, I would favor December through March.
Clearer and drier weather makes outdoor sightseeing much easier, particularly when viewpoints are involved.
If you visit during the wet season, check the weather before heading to exposed viewpoints and mountain areas.
Best Months for Walking the Waterfront
Vung Tau’s waterfront can be enjoyed throughout the year, but the dry season is more comfortable for long walks.
From December to March, early morning and late afternoon are particularly good.
During April and May, avoid the hottest part of the afternoon.
During the rainy season, the best strategy is simply to use the dry periods between showers.
Our Vung Tau Promenade guide covers the different waterfront areas in more detail.
What Should You Pack for Vung Tau?
Because Vung Tau stays warm throughout the year, the basic packing list is simple.
Dry Season
- Lightweight clothing
- Swimwear
- Sunscreen
- Sunglasses
- Hat or cap
- Comfortable walking shoes
Rainy Season
- Lightweight rain jacket or poncho
- Quick-drying clothes
- Waterproof phone protection
- Sandals or shoes suitable for wet conditions
- Swimwear
- Sunscreen
Even in the rainy season, remember that temperatures remain tropical. You need rain protection, not heavy clothing.
Does It Rain All Day in Vung Tau During the Rainy Season?
No.
This is one of the most important things to understand about tropical weather.
A month with many rainy days does not mean that it rains continuously from sunrise to sunset. Rain often comes as showers or thunderstorms, with clearer periods before or after them.
That is why a rainy-season trip can still work if you have enough flexibility.
For a one-day visit, however, the short-term forecast becomes much more important because you have less time to wait for the weather to improve.
Vung Tau Weather vs Other Beach Cities in Vietnam
Vung Tau has one major advantage compared with several other popular Vietnamese beach destinations: its proximity to Ho Chi Minh City makes it easy to choose a short weather window.
You do not necessarily have to book a week-long holiday months in advance.
If the forecast looks excellent for the coming weekend, Vung Tau can be a very practical spontaneous beach escape.
For longer holidays, however, it is still worth choosing the season carefully.
