Spring in Ho Chi Minh City feels hot, humid, and a bit unpredictable as the rainy season starts to show itself. Most days, you’ll see highs near 93°F (34°C), with nights that usually stay above 77°F (25°C).
Clouds can build up quickly, and you might get caught in a brief but heavy shower, especially as May gets closer.
The heat doesn’t really let up, but other weather shifts can change how you experience the city. Humidity rises until the air feels thick almost every day, and rain goes from a rare event to a regular part of the late spring routine.

It helps to know what you’re getting into. From average temperatures and rainfall to sunshine, wind, and air quality, each factor shapes your time in Vietnam’s biggest city during spring.
Here’s a guide with practical tips so you can actually enjoy Ho Chi Minh City—even when the weather changes on you.
Overview of Spring Weather in Ho Chi Minh City
Spring in Ho Chi Minh City means hot days, rising humidity, and a slow move from dry to wet conditions.
You’ll get long daylight hours, bright sunshine, and more clouds as summer monsoon season approaches.
Spring Months and Seasonal Patterns
Spring here covers March, April, and May.
During these months, average highs go from 35°C (95°F) in March to about 34°C (93°F) in May. Nights stay pretty warm, between 25–27°C (77–81°F).
March is still fairly dry, with only 4–5 rainy days, but April and May bring a lot more rain. By May, you’ll see about 12 rainy days a month, which signals the start of the wet season.
Daylight sticks around for about 12.3 hours in April. If you’re planning to be outside, March is your best bet for dry and sunny weather. By May, it’s stickier and less settled.

| March | 35.4 | 25.0 | 4.4 |
| April | 35.3 | 26.4 | 11.6 |
| May | 34.5 | 27.0 | 12.0 |
Tropical Monsoon Climate Characteristics
Ho Chi Minh City sits in a tropical monsoon climate, so spring acts as a bridge between the dry winter and the heavy summer rains.
You’ll feel humidity climb from about 60% in February to more than 75% by May.
Unlike up north, spring here never really cools off. The heat just keeps building as the wet season gets closer.
Afternoon showers pop up more often in April and May. They’re usually short, but they can be intense.
Winds stay light, but by late spring, clouds become much more common. March skies seem clearer, but by May, overcast days are frequent.
This is when the dry northeast monsoon fades, and the wet southwest monsoon takes over.
All these changes make spring hot, humid, and sometimes a bit unpredictable—especially as the rainy season gets near.
Average Temperatures During Spring
Spring in Ho Chi Minh City stays hot and humid, with daytime highs often in the mid-90s °F and warm nights.
April usually stands out as the hottest month before the heavy rains settle in.
Daytime and Nighttime Temperature Ranges
You’ll see daytime highs around 88–97°F (31–36°C) during spring. Late April often brings the peak, with highs near 94°F (34°C).
High humidity can make it feel even hotter.
At night, temps rarely drop below 72–82°F (22–28°C). Cooler evenings are rare, so most people rely on fans or air conditioning.
The warm nights keep that tropical vibe going, even after sunset.
The difference between day and night isn’t huge—usually just 10–15°F (5–8°C). The heat sticks around, so don’t expect much relief once the sun goes down.
Light clothing and regular breaks during the hottest part of the day really help.
Temperature Trends by Month
March starts out with highs near 90°F (32°C) and lows around 73°F (23°C). It’s hot, but the humidity hasn’t peaked yet.
April cranks things up, with highs averaging 93–94°F (34°C) and lows at 77–79°F (25–26°C). This is the hottest month of the year, and you’ll feel it.
May stays hot, with highs around 92–93°F (33–34°C) and lows near 78–80°F (26–27°C). Humidity shoots up, making the air feel even heavier.
That steady climb from March to April, then May’s humid heat, signals that the wet season is just about here.
Rainfall and Humidity Levels
Spring in Ho Chi Minh City marks the shift from dry to wet season.
Rainfall totals and humidity both rise, changing how the weather feels every day.
Monthly Rainfall Totals
Rain picks up fast from March to May as the city heads into monsoon season.
March only brings about 4 to 5 rainy days, and totals stay around 20–30 mm. Most rain is light and doesn’t last long.
April brings more showers—10 to 12 rainy days and about 100 mm in total. Thunderstorms start to show up, usually in the late afternoon, and you might get caught in a heavy burst.
May is when the wet season really kicks off. Rainfall jumps to over 150 mm with 12 or more rainy days. Thunderstorms happen often, and quick, heavy rain can flood low-lying streets.
| Month | Avg. Rainfall (mm) | Rainy Days |
|---|---|---|
| March | ~25 mm | 4–5 |
| April | ~100 mm | 10–12 |
| May | 150–180 mm | 12–14 |
You’ll want to plan for sudden showers, especially in April and May.
Humidity Patterns in Spring
Humidity stays high all year, but in spring, it climbs steadily.
March averages around 70%—not too bad, but you’ll still feel it.
By April, humidity creeps up to 75%, and mornings start to feel sticky.
May brings some of the year’s highest humidity, averaging near 80%.
That extra moisture, mixed with frequent storms, makes the heat feel even more intense.
To stay comfortable, pack light clothes, drink lots of water, and take breaks indoors during the muggiest hours.
Thunderstorms and Weather Events
Spring afternoons in Ho Chi Minh City often end with sudden heavy rain and rumbles of thunder.
These quick storms can really change your plans or the city’s mood in a hurry.
Frequency and Timing of Thunderstorms
Thunderstorms usually hit in the late afternoon or early evening.
Heat and humidity build up all day, and by late afternoon, you get the right mix for strong downpours.
You’ll probably see several storms each week in April and May. Rain often comes in short, heavy bursts instead of dragging on all day.
Lightning and thunder are common. Heavy rain can flood streets fast, especially in low spots.
Most storms move through quickly—often in an hour or less. Afterward, skies usually clear up.
A typical spring storm day:
- Morning: Hot, humid, mostly sunny
- Afternoon: Clouds start to build, humidity rises
- Late afternoon/evening: Heavy rain, thunder, lightning
- Night: Skies clear, but it stays humid
Impact on Daily Life and Travel
Thunderstorms can mess with your plans.
Sudden rain floods roads, slows down traffic, and makes things tough for motorbikes—which most folks use to get around.
You’ll want to add extra travel time and avoid riding during the heaviest downpours.
Outdoor plans work best in the morning when the weather’s usually better. If you’re sightseeing or taking day trips, bring a raincoat or a small umbrella.
Flights and buses usually still run, but short delays can happen. Sometimes, stronger storms knock out power in certain neighborhoods.
On the upside, storms bring cooler air and break up the heat for a while.
If you stay flexible and prepare for sudden changes, you can still make the most of your day.
Sunshine, Wind, and Air Quality
Spring in Ho Chi Minh City brings longer days, steady breezes, and a mix of sun and haze.
You’ll get strong sunlight, mild winds, and air quality that changes with traffic and weather.
Average Hours of Sunshine
You usually get 8 to 11 hours of sunshine per day in spring.
February is the brightest month, but March and April start to see more clouds as the wet season gets closer.
Even as rain picks up in April, the days are still long, with sunrise before 6:30 a.m. and sunset near 6:30 p.m.
That’s plenty of time for outdoor stuff.
The sun packs a punch here since the city sits near the equator. The UV index often hits 7 or higher, so don’t forget hats, sunglasses, and sunscreen.
| Month | Avg. Sunshine Hours | UV Index (approx.) |
|---|---|---|
| Feb | 10–11 | 7–8 |
| Mar | 9–10 | 8 |
| Apr | 8–9 | 8–9 |
Typical Wind Speeds and Directions
Winds in spring usually stay light to moderate—6–10 km/h (4–6 mph). That’s just enough to help with the heat, but not enough to cause any problems.
The city’s spot near the Mekong Delta and South China Sea affects wind direction.
In February and March, winds mostly come from the northeast. By April, they start shifting to the southwest as the wet season approaches.
You might notice breezes picking up in the afternoons, which helps with the humidity and makes being outside more pleasant.
Air Quality Considerations
Air quality in Ho Chi Minh City during spring depends on traffic, construction, and the weather.
Most days, it stays in the moderate range, but pollution can spike when there’s lots of traffic or the air isn’t moving much.
Spring humidity, between 61–70%, can trap particles near the ground, making the air feel heavy.
This is especially noticeable in March and April, as the rain increases.
If you’re sensitive to air pollution, check the daily AQI (Air Quality Index) before heading out. A light mask helps in crowded areas, especially during rush hour.
Most visitors find the air manageable, though February usually feels clearer before the humidity and rain pick up.
Travel Tips for Visiting Ho Chi Minh City in Spring
Spring in Ho Chi Minh City means hot afternoons, humid nights, and more rain as May approaches.
You’ll want to prepare for the heat and those sudden showers, and plan your activities to match both the weather and what’s happening around the city.
What to Pack for Spring Weather
Daily highs usually hit the mid-90s °F (around 34°C), and the humidity just sticks around. You’ll want light, breathable clothing—cotton or linen feels best and dries fast.
Toss in a wide-brimmed hat, some sunglasses, and don’t forget sunscreen. The UV rays can get intense, and honestly, nobody enjoys a sunburn.
Rain really picks up from March through May. I’d suggest grabbing a compact umbrella or a lightweight rain jacket, especially if you plan to walk or hop on a motorbike.
You’ll need comfortable, durable footwear since sidewalks can get slippery or uneven when it rains. Go for sandals with decent grip or some breathable sneakers.
Bring insect repellent for the evenings, because mosquitoes love humid weather. Also, a reusable water bottle comes in handy—hydration matters when it’s this hot.
| Item | Why It’s Useful |
|---|---|
| Light clothing | Keeps you cool in high heat |
| Umbrella/rain jacket | Protection during sudden rain |
| Comfortable shoes | Safe for walking in wet or uneven areas |
| Sunscreen & hat | Shields from strong sun |
| Insect repellent | Reduces mosquito bites |
Best Activities and Events in Spring
Spring feels like the perfect time to get outside and enjoy outdoor sightseeing, especially in the mornings before the heat kicks in. You might want to check out landmarks like the War Remnants Museum, the Notre-Dame Cathedral Basilica, or the Central Post Office.
By late afternoon, people usually head to shaded spots like Tao Dan Park or hang out by the riverside, where things are a bit cooler. Street food tours start to pick up too, since evening markets get lively once the sun goes down.
April tends to bring cultural festivals and public holidays, so you’ll probably catch parades, live music, and all sorts of local celebrations. It’s a fun way to dive into Vietnamese traditions and feel part of the community.
If the heat gets to you, you can always duck into Ben Thanh Market for shopping or chill out in an air-conditioned mall or cafe. That way, you get a mix of culture and a taste of modern Ho Chi Minh City.
