Sunny months: November–April across most of Vietnam. Rainy months: May–October in the north and center. Vietnam typhoon season: July–November, peaking August–October along the central coast. Because Vietnam spans 1,650 km across three climate zones, the weather in Hanoi, Hoi An, and Ho Chi Minh City can be completely different in the same month — always check by region, not just by month.
Vietnam’s weather is one of the most misunderstood topics in Southeast Asia travel planning. Ask ten travelers “when is the best time to visit Vietnam?” and you will get ten different answers — because they all visited different parts of a very long, climatically diverse country. Vietnam weather by month varies dramatically between the north, center, and south, shaped by two opposing monsoon systems that never quite align.
This guide breaks down Vietnam’s weather month by month and region by region — covering temperature, rainfall, humidity, typhoon risk, and what each season actually feels like on the ground. For the complete trip-planning picture, see our best time to visit Vietnam guide.
What this guide covers:
- Vietnam weather by month — all 12 months, all 3 regions
- Vietnam sunny season, rainy season, and typhoon season explained
- Monthly temperature and rainfall averages by city
- Which months to visit for beaches, trekking, and festivals
- The worst months to visit each region
Understanding Vietnam’s Climate: Two Monsoons, Three Zones
Before diving into the month-by-month breakdown, it helps to understand why Vietnam’s weather is so regionally complex. The country’s narrow, S-shaped geography means it sits across two entirely different monsoon systems at the same time.
The Two Monsoon Systems
- Northeast Monsoon (October–April): Blows dry, cool air down from China into northern and central Vietnam. This is the dry, pleasant season for Hanoi and Da Nang — and the wet season for the southern tip.
- Southwest Monsoon (May–September): Pushes warm, moisture-laden air up from the Gulf of Thailand. Brings heavy rain to the north and center, and the main wet season to Ho Chi Minh City.
The Three Climate Zones
- North Vietnam (Hanoi, Sapa, Ha Long Bay): Subtropical — four seasons including a genuine, cold winter (December–February) and a hot, humid summer (June–August).
- Central Vietnam (Hoi An, Da Nang, Hue, Nha Trang): Most weather-volatile. Sunny and dry February–August, then battered by typhoons and floods September–November. The only region with serious typhoon risk.
- South Vietnam (Ho Chi Minh City, Mekong Delta, Phu Quoc): Tropical — two seasons only. Dry (November–April) and wet (May–October). No typhoons. No cold. Rain falls in short afternoon bursts year-round.
Vietnam Weather by Month — Full Breakdown
January Weather in Vietnam
January in North Vietnam (Hanoi, Sapa, Ha Long Bay)
January is the coldest month in Hanoi, with temperatures ranging from 14–19°C. The city has a crisp, European winter feel — cool enough to require a jacket but rarely cold enough to be uncomfortable. Skies are mostly clear and dry. Sapa can drop to near-freezing at night (3–8°C) and occasionally sees light snow on the highest peaks — a rare and magical sight. Ha Long Bay cruises run normally in January with calm seas and good visibility, though morning mist is common.
- Hanoi: 14–19°C | Low rainfall | Cool & clear
- Sapa: 3–12°C | Occasional fog | Possible snow at altitude
- Ha Long Bay: 15–20°C | Calm seas | Light morning mist
January in Central Vietnam (Hoi An, Da Nang, Hue)
January marks the tail end of the northeast monsoon for central Vietnam. Da Nang and Hoi An are cool (19–23°C) and mostly dry, with occasional light showers. The flooding of October and November has long passed. This is a pleasant, uncrowded time to explore the Ancient Town and the surrounding beaches — water is still a little cool for swimming but the atmosphere is wonderful.
- Hoi An / Da Nang: 19–23°C | Low rainfall | Mostly dry & pleasant
- Hue: 17–21°C | Light showers possible | Cool & atmospheric
January in South Vietnam (Ho Chi Minh City, Phu Quoc)
January is peak season in the south. Ho Chi Minh City is warm (22–32°C), dry, and buzzing with energy. Phu Quoc is at its absolute best — crystal-clear water, minimal waves, and long sunny days. This is the most popular month for beach holidays in southern Vietnam.
- Ho Chi Minh City: 22–32°C | Very low rainfall | Sunny & busy
- Phu Quoc: 24–31°C | Calm seas | Peak beach season
February Weather in Vietnam
February is one of the finest months to visit Vietnam, with excellent weather across all three regions. It also brings Vietnam Tet festival — the Lunar New Year, usually falling in late January or February. The country transforms: flower markets appear overnight, cities are strung with lights, and the atmosphere is unlike anything else in Southeast Asia. Book everything 3–4 months ahead if visiting around Tet — accommodation, transport, and tours sell out completely.
- Hanoi: 16–21°C | Low rainfall | Mild & pleasant | Tet decorations city-wide
- Hoi An: 20–24°C | Very low rainfall | Start of best season
- Ho Chi Minh City: 23–33°C | Very low rainfall | Warm & dry
- Phu Quoc: 24–32°C | Calm seas | Excellent beach conditions
March Weather in Vietnam
March is the single best month to visit Vietnam for travelers covering multiple regions. All three zones are warm, dry, and at or near their weather peak simultaneously — a rare alignment that makes March the ideal month for a north-to-south itinerary. Crowds are moderate (lower than Tet season), prices are mid-range, and the landscape is lush after winter. This is the month that experienced Vietnam travelers consistently recommend to first-timers.
- Hanoi: 19–24°C | Low rainfall | Warm & clear — ideal sightseeing
- Hoi An / Da Nang: 23–27°C | Very low rainfall | Best beach weather
- Ho Chi Minh City: 24–34°C | Low rainfall | Hot but manageable
- Phu Quoc: 25–33°C | Excellent sea conditions | Peak diving season
- Sapa: 10–18°C | Low rainfall | Spring flowers blooming
April Weather in Vietnam
April continues March’s excellent conditions, though temperatures begin climbing toward summer levels in the south (32–35°C in Ho Chi Minh City). The north remains warm and pleasant (23–28°C in Hanoi). Central Vietnam is at its best — Da Nang’s beaches are buzzing, Hoi An’s evenings are warm and golden, and Hue’s imperial sites are at their most photogenic. The last reliably dry month for central Vietnam before the summer heat builds.
- Hanoi: 22–28°C | Low rainfall | Warm & sunny
- Hoi An / Da Nang: 25–30°C | Low rainfall | Peak beach season
- Hue: 24–29°C | Low rainfall | Ideal for heritage sites
- Ho Chi Minh City: 25–35°C | Low rainfall | Hot & dry
- Nha Trang: 26–31°C | Low rainfall | Excellent diving conditions
May Weather in Vietnam
May is the transitional month where Vietnam’s weather begins to split. The southwest monsoon arrives, bringing increasing heat and humidity to the north and the start of the wet season in central Vietnam. However, southern Vietnam remains excellent — Ho Chi Minh City and the Mekong Delta are still very manageable, and prices drop 20–30% from peak. May is a smart pick for budget travelers focused on the south.
- Hanoi: 26–32°C | Medium rainfall | Getting hot & humid
- Hoi An / Da Nang: 27–32°C | Increasing rainfall | Last reliable beach month
- Ho Chi Minh City: 24–33°C | Low–medium rainfall | Still very pleasant
- Phu Quoc: 26–32°C | Seas getting rougher | Book early months of May
June Weather in Vietnam
June marks the full arrival of Vietnam’s rainy season in the north and center. Hanoi is hot (30–34°C) and increasingly wet. Da Nang and Hoi An see frequent afternoon downpours. The southwest monsoon is now dominant across most of the country. However, Ho Chi Minh City still sees mostly short afternoon showers — the mornings are reliably dry, making urban sightseeing largely unaffected. Prices are at their lowest of the year — up to 35% below peak.
- Hanoi: 28–34°C | High rainfall | Hot, humid & wet — avoid outdoor activities
- Hoi An / Da Nang: 28–33°C | High rainfall | Beaches largely unusable
- Ho Chi Minh City: 23–32°C | Afternoon showers | Mornings dry — still workable
- Phu Quoc: 25–31°C | Rough seas | Ferry cancellations possible
July Weather in Vietnam
July is widely considered the worst month to visit Vietnam. The combination of peak typhoon season in the center, extreme heat and humidity in the north, and widespread wet conditions across the country makes it the most challenging travel month of the year. For the complete breakdown of what to avoid, see our worst time to visit Vietnam guide.
- Hanoi: 29–35°C | Very high rainfall | “Feels like” 42°C+ with humidity | Outdoor sightseeing miserable
- Hoi An / Da Nang: 27–32°C | High rainfall | Typhoon risk begins | Beach season over
- Ho Chi Minh City: 24–31°C | High rainfall | Still manageable for urban travel
- Sapa: 15–22°C | Heavy rain | Trails dangerously slippery | Landslide risk on mountain roads
August Weather in Vietnam
August sustains all of July’s problems and adds more. Statistically, August sees the highest number of typhoon landfalls along the central Vietnam coast. Ha Long Bay cruise operators frequently cancel or reroute itineraries due to storm warnings. Sapa’s mountain roads become dangerous after sustained heavy rain. The only silver lining: prices are at their annual floor — some properties offer 40–50% discounts — and Ho Chi Minh City remains a viable base for urban and cultural travel.
- Hanoi: 28–34°C | Very high rainfall | Hottest and wettest month
- Hoi An / Da Nang: 27–31°C | Very high rainfall | Highest typhoon risk month
- Ha Long Bay: Frequent cruise cancellations | Not recommended
- Ho Chi Minh City: 23–31°C | High rainfall | Urban travel still viable
September Weather in Vietnam
September is Vietnam’s most regionally divided month. Central Vietnam faces its highest flood risk of the year — Hoi An regularly floods in September and October combined. But northern Vietnam begins cooling and drying out, and Sapa enters its most celebrated season: the golden rice terrace harvest. Mu Cang Chai and Sapa’s terraced valleys turn a breathtaking amber-gold from mid-September through October — one of the most photographed natural spectacles in all of Vietnam. See our Sapa trekking guide for the best routes during harvest season.
- Hanoi: 26–31°C | Decreasing rainfall | Cooling down pleasantly
- Sapa: 13–19°C | Moderate rain | Golden rice terrace harvest — spectacular
- Hoi An / Da Nang: 25–29°C | Very heavy rainfall | High flood risk — avoid
- Ho Chi Minh City: 23–31°C | High rainfall | Still manageable
October Weather in Vietnam
October is one of Vietnam’s most paradoxical months. Hanoi enters its golden season — the finest weather of the year, with crisp blue skies, temperatures of 22–27°C, and the city looking its most beautiful. Ho Chi Minh City begins drying out. But central Vietnam — Hoi An, Da Nang, and Hue — hits peak flood season. The Thu Bon River regularly bursts its banks. In 2020, Hoi An’s Ancient Town was completely submerged for five days. October in central Vietnam is not just inconvenient — it can be genuinely dangerous.
- Hanoi: 22–27°C | Low rainfall | Best month of the year — crisp and beautiful
- Sapa: 10–17°C | Low rainfall | Tail end of golden terrace season
- Hoi An / Da Nang: 23–26°C | Extreme rainfall | Peak flood risk — avoid entirely
- Hue: 22–25°C | Extreme rainfall | Serious flood risk
- Ho Chi Minh City: 23–31°C | Decreasing rain | Drying out nicely
November Weather in Vietnam
November marks the turning point when Vietnam’s peak travel season begins in earnest. The northeast monsoon takes hold, drying out the north and center while keeping the south warm and sunny. Hanoi is cool and clear (19–24°C). Hoi An finally emerges from the flood season — by mid-November, conditions are largely dry and the Ancient Town is at its atmospheric best in the cool evening air. Ho Chi Minh City fully enters dry season. Prices and crowds begin rising toward the December–February peak.
- Hanoi: 19–24°C | Low rainfall | Beautiful autumn weather continuing
- Hoi An / Da Nang: 21–25°C | Decreasing rain | Recovering — check forecast before booking early November
- Ho Chi Minh City: 22–31°C | Low rainfall | Dry season begins
- Phu Quoc: 24–31°C | Calm seas returning | Great time to visit
- Ha Long Bay: 18–23°C | Calm seas | Cruise season fully open
December Weather in Vietnam
December is one of the finest months to visit Vietnam. The northeast monsoon is fully established, delivering dry, clear conditions across the entire country simultaneously. Hanoi has a cool, romantic winter feel (14–19°C) — perfect for wandering the Old Quarter and drinking egg coffee in lakeside cafes. Hoi An is dry, warm (19–23°C), and less crowded than the March–April peak. Ho Chi Minh City and Phu Quoc are in full dry season glory. December is the ideal month to start a comprehensive north-to-south Vietnam itinerary.
- Hanoi: 14–19°C | Very low rainfall | Cool winter feel — bring a layer
- Hoi An / Da Nang: 19–23°C | Low rainfall | Dry & pleasant
- Ho Chi Minh City: 21–30°C | Very low rainfall | Warm & sunny peak season
- Phu Quoc: 23–30°C | Calm seas | Excellent beach & diving conditions
- Ha Long Bay: 15–20°C | Calm seas | Clear visibility — best cruise month

Vietnam Rainy Season: When Is It and What Is It Like?
Vietnam does not have a single rainy season — it has three overlapping wet seasons that hit different regions at different times:
| Region | Rainy Season | Peak Rainfall | What It Feels Like |
|---|---|---|---|
| North Vietnam | May – September | July – August | Heavy afternoon downpours, high humidity, flooding in Hanoi Old Quarter |
| Central Vietnam | September – November | October – November | Multi-day torrential rain, river flooding, typhoon risk, Hoi An can flood completely |
| South Vietnam | May – October | June – August | Short afternoon bursts (1–2 hours), mornings usually dry, rarely disrupts travel |
The key difference between north/center and south rainy seasons: In the south, the rainy season is gentle — short intense showers that clear up quickly. In the north, monsoon rain is heavy and sustained. In the center, the wet season brings genuine danger — multi-day flooding that can make roads impassable and cause serious property damage.

Vietnam Typhoon Season: What You Need to Know
Vietnam’s typhoon season is one of the most important factors in travel planning — and the most commonly misunderstood. Here is everything you need to know:
- Active months: June to November, peaking August to October
- Most vulnerable region: Central Vietnam coastline — Da Nang, Hoi An, Hue, Nha Trang
- Average typhoons per year: 6–8 make direct impact on Vietnam
- Typhoon speed: Can intensify from tropical storm to Category 3 in under 48 hours
- North Vietnam: Occasionally affected by weakened typhoons — mostly heavy rain rather than destructive winds
- South Vietnam: Almost never directly hit by typhoons — the geography of the South China Sea protects the southern coast
June: Low | July: Moderate | August: High | September: High | October: Very High | November: Moderate | December: LowAlways check the Joint Typhoon Warning Center (JTWC) forecast before and during travel to central Vietnam between July and November. Purchase travel insurance covering typhoon and storm cancellations.

Frequently Asked Questions
What months are sunny in Vietnam?
The sunniest months across all three regions simultaneously are January, February, March, April, and December. Northern Vietnam is sunniest October–April. Central Vietnam is sunniest February–August. Southern Vietnam is sunniest November–April. March is the single month where all three regions enjoy sunny, dry conditions at the same time.
What months are rainy in Vietnam?
Vietnam’s rainy season months vary by region. The north is wettest May–September. Central Vietnam is wettest September–November (flood season). The south is wettest May–October, though rain is typically short afternoon showers rather than sustained downpours. The safest way to avoid rain is to visit November–April and plan by region rather than by month alone.
When is Vietnam typhoon season?
Vietnam’s typhoon season runs June to November, peaking August to October. The central coastline — Da Nang, Hoi An, Hue — is most at risk. The north is occasionally affected by weakened storms. The south is rarely directly hit by typhoons. Avoid central Vietnam entirely August–October if typhoon disruption is a concern for your trip.
What is the best month to visit Vietnam for good weather?
March is the best month for good weather across all of Vietnam simultaneously — all three regions are warm, dry, and pleasant at the same time. November to April is the extended window of reliably good weather for most of the country. For the full trip-planning guide, see our best time to visit Vietnam guide.
Is it hot in Vietnam all year round?
In southern Vietnam — yes, it is hot and tropical year-round (always above 28°C). In northern Vietnam — no. Hanoi has a genuine winter (December–February) where temperatures drop to 12–17°C, cold enough to require a jacket. Central Vietnam is pleasantly warm most of the year but cool and sometimes cold (19–22°C) in January and December.
What is Vietnam weather like in December?
December is excellent across all regions. Hanoi is cool and crisp (14–19°C), Hoi An is dry and warm (19–23°C), and Ho Chi Minh City is in peak dry season (21–30°C). December is one of the best months for a full north-to-south Vietnam itinerary.
