Vietnam Rainy Season Guide: When It Rains, Typhoons, and How to Plan Around Them
"Is it the rainy season in Vietnam?" is one of the most searched travel questions about the country — and the honest answer is that it depends where you are. Because Vietnam stretches over 1,600 km from north to south, its three main regions have very different weather patterns. While the south is drenched, the central coast can be sunny, and vice versa. Understanding these patterns lets you plan a great trip in almost any month.
Rainy Season by Region
| Region | Main rainy season | Wettest months | Driest months |
|---|---|---|---|
| North (Hanoi, Ha Long, Sapa, Ninh Binh) | May – September | July – August | October – April |
| Central (Hue, Da Nang, Hoi An, Phong Nha) | September – December | October – November | February – August |
| South (Ho Chi Minh City, Mekong Delta, Phu Quoc) | May – October/November | August – October | December – April |
| Central Highlands (Da Lat) | May – October | August – October | November – April |
Northern Vietnam
Summer in the north is hot, humid, and rainy, with heavy afternoon thunderstorms. Rain rarely lasts all day, but mountain areas like Sapa and Ha Giang can see landslides that block roads. Ha Long Bay cruises may be cancelled when storms approach.
Central Vietnam
The central coast has a reversed pattern. Its rainy season runs from roughly September to December, peaking in October and November, when typhoons and tropical depressions often make landfall. Hoi An's Old Town floods almost every year, sometimes with water up to waist height in riverside streets. Hue and Quang Tri can also see serious flooding.
Southern Vietnam
The south has a classic tropical wet season. Expect short, intense downpours most afternoons, typically lasting 30 minutes to two hours, followed by sunshine. Mornings are often clear, so plan sightseeing early. Phu Quoc's west coast gets rougher seas and more rain from June to October.
Typhoon Season in Vietnam
Typhoons (tropical storms) can affect Vietnam from roughly June to November. Storms tend to hit the north earlier in the season (July–September) and the central coast later (September–November). The far south is rarely struck directly.
How typhoons affect travel
- Flights and trains may be delayed or cancelled for a day or two.
- Boat trips in Ha Long Bay, Lan Ha Bay, and to islands like Cu Lao Cham and Con Dao are suspended when storm warnings are issued.
- Caves and national parks, including Phong Nha, may close during floods.
- Mountain roads can be closed by landslides.
How to track storms
Follow Vietnam's National Center for Hydro-Meteorological Forecasting, international trackers such as the Joint Typhoon Warning Center, and local news. Your hotel will usually know the latest situation and any official instructions.
Pros of Traveling in the Rainy Season
- Lower prices on hotels and tours, and fewer crowds at major sights.
- Lush green landscapes — rice terraces and the Mekong Delta are at their most vivid.
- Cooler air after downpours.
- Seasonal fruit, including mangosteen, rambutan, and durian, is abundant in the south.
Practical Tips for Wet-Season Travel
- Build flexibility into your itinerary. Leave a buffer day before international flights and avoid fixed boat trips on your last day.
- Pack a lightweight rain jacket, quick-dry clothes, and sandals. A poncho can be bought anywhere for a few dollars — see our packing list.
- Use waterproof bags for your phone, passport, and electronics.
- Book refundable or flexible accommodation in central Vietnam during October and November.
- Get travel insurance that covers weather disruption and trip cancellations.
- Avoid riding motorbikes in heavy rain or on mountain passes during storms.
- Follow local advice — if your hotel or guide says a trip is unsafe, believe them.
Where to Go in Each Rainy Month
- May–September: Head to central Vietnam (Hoi An, Da Nang, Hue, Quy Nhon), which is dry and sunny.
- October–November: Go north (Hanoi, Ha Giang, Ninh Binh) or south (Ho Chi Minh City — the rains are easing by November).
- December–April: The south and Phu Quoc are at their best; the north is cooler and drier.

Frequently Asked Questions
What is the worst month to visit Vietnam?
There's no single worst month for the whole country. October–November is risky for central Vietnam due to floods and typhoons, while July–August is the wettest period in the north.
Does it rain all day during the rainy season?
Usually not. In the south and north, rain typically comes as heavy afternoon showers. Central Vietnam's autumn rains can be more prolonged, sometimes lasting several days.
Is it safe to visit Hoi An in the flood season?
Generally yes, with caution. Floods are a regular part of life and locals are well prepared, but some areas may be inaccessible for a day or two. Stay somewhere away from the riverfront and follow official warnings.
Will my Ha Long Bay cruise be cancelled in typhoon season?
It can be. Authorities suspend all boat departures when storms approach. Reputable operators will reschedule or refund you.
A little rain shouldn't put you off Vietnam. With smart regional planning and some flexibility, the wet season can be one of the most rewarding — and best-value — times to visit.
