Vietnam Weather in July 2025: See the Best & Worst Travel Secrets

July marks the peak of Vietnam's summer monsoon, with northern and southern regions experiencing their highest rainfall of the year (200-300mm). Central Vietnam, however, remains in its dry season, averaging less than 60mm of rain — ideal for beachgoers.

Temperatures nationwide exceed 31°C (88°F), with northern plains like Hanoi frequently surpassing 40°C (104°F).

So, is July a good time to go to Vietnam?

July is great for Central Vietnam beaches but challenging for Northern and Southern Vietnam due to the rain and heat. If you plan to visit, book early, start your days early, and be ready for afternoon rain in the south.

Best move? Stick to Hoi An, Da Nang, and Nha Trang for the best weather. For cooler and drier weather across the country, consider November to April.

Hanoi & Northern Vietnam: Hot Days, Afternoon Rains, and Lush Scenery

• Best Destinations: Hanoi, Ninh Binh
• Challenging Areas: Halong Bay (possible typhoons), Sapa (fog and slippery trails)

July in Northern Vietnam is one of the hottest and wettest months, with temperatures soaring past 33°C (91°F) in Hanoi and Ninh Binh. Some days can even hit 40°C (104°F). Up in the mountains, places like Sapa are much cooler, hovering around 24-25°C (75-77°F), though rain and mist can limit visibility.

Best Things to Do in Northern Vietnam in July

In Hanoi, take an early morning walking through the Old Quarter and grab pho as locals, and escape the heat in the Temple of Literature with its shaded courtyards.

Ninh Binh shines in July with golden rice fields, blooming waterlilies, and stunning karst landscapes. If you're keen on the iconic Halong Bay cruise, schedule it in early July for less risk of storms and typhoons.

For a cooler escape, head to Sapa, where the misty mountains offer a refreshing break. With rainy days, focus on cultural experiences—visit Sapa Market and meet local artisans for a hands-on experience of traditional mountain life.

What to Watch Out For:

• Hanoi's streets can flood after heavy rain (over twice in July), so waterproof sandals are a good idea.
• Late July typhoons can impact Halong Bay cruises. If you want dramatic limestone landscapes, Ninh Binh is a safer bet.
• Trekking in Sapa can be tricky, with muddy trails and thick mist covering the mountain views.

Hoi An & Central Vietnam: The Best Place to Be in July

• Best Destinations: Da Nang, Hoi An, Nha Trang, Quy Nhon, Hue

July is the perfect time to visit Central Vietnam, with long sunny days (over 8+ hours of sunshine daily), warm beaches, and little rain. It's hot but dry, with temperatures averaging 32-35°C (90-95°F)—perfect for a beach escape.

Best Things to Do in Central Vietnam in July

For outdoor lovers, explore hidden caves in Phong Nha, dive in Nha Trang (July is the best time), or ride through the scenic Hai Van Pass.

Traveling with kids? Take the world's longest ocean-crossing cable car to Vinpearl Land, join a lantern-making workshop, or cycle through Hoi An's rice fields and snap fun photos at Da Lat's Crazy House.

For cultural experiences, don't miss My Son Sanctuary. Morning visits are best to escape the heat.

What to Watch Out For:

• Avoid sightseeing in the midday heat. Mornings and late afternoons are much more comfortable.
• Hoi An gets very crowded in the evening. Arriving in the late afternoon allows you to experience its charm without the rush.

Ho Chi Minh & Southern Vietnam: Tropical Rains

• Best Destinations: Ho Chi Minh City, Mekong Delta
• Challenging Areas: Phu Quoc (heavy rain and rough seas)

In Southern Vietnam, July brings afternoon thunderstorms, but they rarely last more than one to two hours. The rest of the day is often warm and sunny, with temperatures around 31-33°C (88-91°F).

Best Things to Do in Southern Vietnam in July

In Ho Chi Minh City, start your day with a morning Vespa tour, exploring local markets and savoring an authentic Vietnamese breakfast. For history buffs, the Cu Chi Tunnels, the Long Tan Cross, and Nui Dat are best explored in the morning before the afternoon rains as well.

For a deeper experience, spend a night on a private sampan in the Mekong Delta. Wake up early for a sunrise boat ride through the floating markets. You could see vendors paddling from boat to boat, selling fresh coconuts, hot noodle soup, and ripe tropical fruits.

What to Watch Out For:

• Phu Quoc's west coast faces rough seas in July due to southwest monsoons, but the east coast's Sao Beach remains swimmable. Morning snorkeling trips are feasible (rainfall peaks after 2 PM), and lower tourist numbers mean discounted resorts.
• Afternoon showers in Ho Chi Minh City are sudden but short, so carrying a small umbrella or rain jacket is a good idea.

Crowds & Travel Costs in July

July is peak travel season with both local and international students on summer break, so expect beaches to be packed and hotels to fill up fast, especially in Da Nang, Hoi An, and Nha Trang.

Flights and rooms get pricey, so booking a month or two ahead saves the hassle. Popular sights can be crowded, but if you head out early or wait until late afternoons, you'll dodge the worst of it.

What to Wear in July in Vietnam

• Sun protection: sunscreen, hat, sunglasses
• When it rains: waterproof rain jacket, umbrella, rubber boots
• Loose, breathable clothing that covers your knees and shoulders for cultural sensitivity and sun protection
• Light, quick-drying clothes for humid days
• Swim shorts, bathing suit, and flip flops for a beach vacation
• Insect repellent as mosquitoes are at their peak in the rainy summer.
