The historic floods in 2025: A rare and devastating event

The year 2025 will be remembered in Vietnam’s history marked by unprecedented flooding, an event described by experts as rare and occurring only once in several decades. What made the floods in Vietnam in 2025 noteworthy was their intensity and frequency. Vietnam is no stranger to heavy rains, but the climate change makes extreme weather more frequent and unpredictable. Between January and October alone, extreme weather events caused deaths and economy damages nationwide.

Heavy rains, exacerbated by multiple typhoons and climate change influences, led to catastrophic floods across the country. Beginning in August and intensifying through November, these floods affected major cities and rural areas alike, with Ho Chi Minh City experiencing unusual inundation in August and early November, followed by Hanoi facing two weeks of submersion due to three consecutive typhoons.

In the south-central regions, relentless rainfall triggered landslides and widespread inundation, stranding hundreds and causing economic losses. Regions like Dak Lak, Gia Lai, Lam Dong, and Khanh Hoa provinces saw rivers swell to dangerous levels, leading to mudslides and flooding in low-lying areas. This event was part of a broader Southeast Asian crisis, affecting neighboring countries like Thailand, Malaysia, Indonesia, and the Philippines.

Flood period in Vietnam

Vietnam’s flood period is closely tied to its monsoon climate, influenced by geographical features as well as the tropical storms in Vietnam. While the country as a whole experiences heavy rainfall during certain months, the timing and intensity vary significantly across its three main regions: the North, Central, and South. These regional differences are shaped by Vietnam’s elongated shape, encompassing diverse terrains from mountainous highlands to river deltas. Understanding these patterns is essential for planning a trip, as floods in Vietnam often result from prolonged rains, river overflows, and poor urban drainage.

In Northern Vietnam

In Northern Vietnam, encompassing areas like Hanoi, Sapa, and Ha Long Bay, the floods typically align with the summer monsoon from May to October. This period brings warm temperatures and frequent showers, with peak rainfall in July and August, averaging 200-300mm per month. The Red River Delta is particularly vulnerable, where heavy rains can cause rivers to swell, leading to flash floods in low-lying areas and landslides in mountainous regions like Sapa.

Typhoons occasionally influence the north, especially from June to November, with the highest risk between June and August. These storms bring intense downpours, strong winds, and potential flooding. However, the north’s flood risks are generally lower compared to central regions, and the season tapers off by October, giving way to cooler, drier weather. Travelers should note that while floods are less frequent, they can disrupt trekking in Sapa or boat cruises in Ha Long Bay during heavy rains.

In Central Vietnam

Central Vietnam, including destinations like Hue, Da Nang, Hoi An, and Nha Trang, experiences its rainy season primarily from September to January, with the most severe risks in October and November. This region is the hardest hit by typhoons, which peak from September to October, often causing catastrophic floods due to the narrow coastal strip backed by mountains. Rainfall can exceed 500mm in a single month, leading to river overflows, landslides, and urban inundation.

The central coast’s geography amplifies flood risks. Mountains trap moisture from the ocean, resulting in prolonged downpours. Hoi An, for instance, often sees minor flooding even in typical years, but major events can submerge streets for days. While the dry season from February to August offers sunny skies, the transition into flood season can be abrupt, so monitoring forecasts is crucial for beach visits or exploring ancient sites.

In Southern Vietnam

Southern Vietnam, covering Ho Chi Minh City, the Mekong Delta, and Phu Quoc Island, has a rainy season from May to November. Rainfall is consistent but less intense than in the central region, peaking in September and October with about 200-250mm monthly. The Mekong Delta’s flat terrain and extensive river network make it prone to seasonal flooding, where rising waters from upstream countries like Cambodia combine with local rains to inundate farmlands and villages.

Unlike the north and central areas, southern floods are often slow-rising and predictable, tied to the Mekong River’s annual swell. However, urban areas like Ho Chi Minh City face flash floods due to inadequate drainage during heavy showers. Typhoons rarely directly hit the south but can bring peripheral rains. The season eases by December, ushering in dry, sunny weather ideal for delta boat tours or island trip.

By recognizing these regional variations, you can tailor your Vietnam itineraries to minimize risks, perhaps combining northern adventures in winter with southern escapes in summer. At Paradise Travel, we customize trips based on these patterns, ensuring your journey is both safe and spectacular.

Flood-prone areas in Vietnam

Certain regions in Vietnam are more susceptible to flooding due to geography and climate. Central Vietnam tops the list: Hue’s Perfume River can rise significantly, submerging historic sites. Hoi An, a UNESCO World Heritage site, often faces severe inundation, with the Hoai River overflowing from dam releases and rains. Nha Trang and Da Lat in the coastal and highland areas are frequently hit hard, affecting coffee belts and leading to tourist evacuations. Highland provinces like Dak Lak and Gia Lai experience mudslides, while the Mekong Delta in the south deals with annual river overflows.

For travelers, it is important to avoid low-lying areas during rains, not driving through flooded roads, and heeding embassy alerts like those from the U.S. Embassy warning against travel to affected zones.

The impacts of floods on travel plans in Vietnam

Vietnam’s flood season can significantly influence travel itineraries, requiring flexibility and preparation. Sudden heavy rains may lead to road closures, flight delays, or cancellations of outdoor activities, such as trekking in national parks or boat tours in Ha Long Bay. Persistent rains may submerge tourist hotspots, forcing evacuations and disrupting ferry services, which extended travel times and altered plans for many visitors.

Travelers might need to reroute journeys, opt for indoor experiences, or extend stays in safer locations. Transportation is particularly affected: trains and buses in central regions can halt during typhoons, while air transfer faces turbulence and delays. Accommodation bookings may shift, with hotels in flood-prone areas closing temporarily. However, this season also offers advantages like fewer crowds, vibrant greenery, and discounted rates.

By embracing flexibility, you can turn potential disruptions into opportunities to delve deeper into Vietnam’s indoor cultural treasures, such as museums or cooking classes, fostering a more authentic travel experience.

How the tourism industry prepares and responds to floods

Vietnam’s tourism industry has evolved robust strategies for flood preparedness. Agencies like Paradise Travel inform clients about climatic risks in advance, recommending ideal seasons and alternative itineraries. Investments in upstream forest restoration and wetlands help naturally mitigate floods. During such events, rapid evacuations, such as boating tourists from Hoi An, save lives. Post-flood, cleanups restore sites quickly, with residents clearing mud and repairing infrastructure.

Safety tips for navigating floods in Vietnam

Navigating Vietnam’s flood season doesn’t mean putting your travel on hold. It simply requires smart planning, awareness, and a spirit of adaptability. With the right preparation, you can still immerse yourself in the country’s rich tapestry of culture, cuisine, and history. At Paradise Travel, we’ve helped thousands of adventurers turn potential rainy days into unforgettable experiences, and we’re here to do the same for you.

Best times to visit Vietnam and avoid floods

Overall, the dry season from November to April offers the most reliable conditions nationwide, with lower humidity, pleasant temperatures, and minimal flood risks. This period coincides with festivals like Tet (Lunar New Year) in January or February, adding cultural vibrancy to your journey. However, for a balanced nationwide tour, consider March to April or September to December, when temperatures are comfortable (around 20-30°C) and rainfall is sparse, ideal for hiking, beach lounging, or city sightseeing.

• In Northern Vietnam, aim for October to December for warm, sunny days perfect for cruising Ha Long Bay or trekking in Sapa’s terraced rice fields. From March onwards, it heats up, making May, June, and September excellent for avoiding both floods and extreme heat.
• Central Vietnam shines from February to August, with dry, sunny weather suiting beach days in Nha Trang or wandering Hue’s imperial citadel. Avoid September to November, the peak typhoon months, when floods are most likely. Instead, time your visit for blooming seasons in March-April or harvest time in October-November for scenic beauty without the risks.
• Southern Vietnam is welcoming year-round, but November to April’s dry season is prime for Mekong Delta boat rides or relaxing on Phu Quoc’s beaches, with temperatures hovering around 25-32°C and rare floods. If visiting during the shoulder months like May or October, you’ll enjoy fewer crowds and lush landscapes, though brief afternoon showers are common.

Accommodation choices for flood season

Selecting the right accommodation can make all the difference in comfort and safety during floods. Opt for hotels or resorts on higher ground or elevated structures to minimize inundation risks. In cities like Hanoi or Ho Chi Minh City, choose modern buildings with good drainage; in rural areas like the Mekong Delta, elevated homestays or eco-lodges are ideal.

Look for properties with flood-preparedness measures, such as backup generators and emergency kits. Read reviews if there are past flood experiences and book rooms on upper floors. Boutique hotels in safer zones, like Da Nang’s urban centers, offer indoor amenities like spas and restaurants. At Paradise Travel, we recommend vetted accommodations that prioritize guest safety, turning your stay into a cozy retreat even amid rains.

Transportation tips for safe navigation

Floods can disrupt travel, so flexibility is important. Avoid self-driving transportations, such as motorbike or scooter, in wet weather conditions. Instead, if conditions are not severe, choose a reputable taxi, ride-hailing apps like Grab or rent a private car with driver in Vietnam. Trains and domestic flights are safest in such weather, but check your airline’s app or website for delays.

In flood-prone areas, use elevated buses or ferries with safety records. During typhoons, limit movement and follow local advisories. Build buffer time into your schedule for rerouting. Paradise Travel arranges private transfers with experienced drivers, ensuring smooth transitions and peace of mind as you explore Vietnam’s diverse landscapes.

Packing essentials

Packing smartly prepares you for variable weather without overburdening your luggage. Essentials include:

• Waterproof clothing: Waterproof jackets, rain coat, and quick-dry pants to stay comfortable.
• Footwear: Sturdy rain boots or slip resistant sandals for navigating wet streets.
• Gear: Waterproof backpack, dry bags to carry electronics, and a portable charger in case of power outage.
• Health items: Insect repellent, sunscreen (for sunny breaks), and basic medications.
• Also bring umbrella, reusable water bottle, and lightweight layers for temperature shifts.

Emergency preparation

Being prepared for emergencies turns potential crises into manageable situations. Assemble an emergency kit with first-aid supplies, flashlight, whistle, cash in VND, and copies of important documents. Follow evacuation routes and local emergency numbers in Vietnam (115 for medical, 114 for fire).

Register with your embassy for alerts and check official news sources for updates in Vietnam. Practice scenarios, such as what to do if stranded, and have a plan for contacting loved ones. In the event of flooding, avoid affected areas and heed warnings. Paradise Travel offers 24/7 support, including emergency assistance, so you can travel with confidence.

Alternative destinations and indoor activities

If floods hit, reroute to the northern and southern areas, which often experience milder rains. These spots provide a cooler, less humid escape with easy access to cultural sites. Stay in the bustling metropolis, where modern infrastructure provides shelters and minimizes disruptions. Focus on city explorations with indoor malls and museums, blending shopping with history for a dynamic alternative. During central typhoons, Phu Quoc remains relatively dry and offers pristine beaches with resort-based activities. Luxury properties here are designed for all-weather enjoyment, featuring indoor pools, gourmet dining, and wellness centers—ideal for a relaxing pivot from mainland adventures.
