What the Weather’s Like in Vietnam, Cambodia, and Laos? Climate Overview

Weather across Vietnam, Cambodia, and Laos changes more than you might expect. From chilly mountains in the north of Vietnam to hot river valleys in Laos, each region has its own rhythm. Your Vietnam Cambodia Laos tour depends a lot on when and where you go.

Vietnam Climate: Diverse Climate Changes by Region
Vietnam has the most diverse climate among the three countries, due to its long north-to-south stretch. The weather changes significantly by region. In general, October to April is the best time to go to Vietnam.

Northern Vietnam (Hanoi, Sapa): This area experiences four distinct seasons. Winters (December–February) can be cold and misty, especially in the mountains. Summers are hot and humid.

Central Vietnam (Hue, Hoi An): The climate here is tropical. It has a dry season from February to August and a rainy season from September to January, sometimes affected by typhoons.

Southern Vietnam (Ho Chi Minh City, Mekong Delta): This region is warm all year. It has two main seasons — a dry season from November to April and a rainy season from May to October.

Cambodia Climate: Dry Season & Wet Season
Cambodia’s weather is more straightforward, with two main seasons. The dry season runs from November to April, while the wet season lasts from May to October. However, dry doesn’t always mean ideal — March and April can be extremely hot, and the countryside often looks dry and dusty. November to February is the best time to visit Cambodia. On the other hand, the wet season brings short afternoon showers, refreshing the landscape with lush greenery and attracting fewer tourists.

Laos Climate: Varied by Region
Laos, being landlocked and mountainous, has more temperature variation by region. In higher areas like Luang Prabang or the Bolaven Plateau, it’s cooler, especially at night. Meanwhile, river valleys near the Mekong tend to be hotter and more humid. Laos follows a similar seasonal pattern: dry from November to March, and wet from May to October. For many travelers, the dry season is considered the best time to visit Laos, especially for exploring the countryside and mountain regions in comfort.

November to February: Golden Season & Peak Travel Time for Vietnam, Cambodia, and Laos

November to February is the perfect time across Vietnam, Cambodia, and Laos. This is the golden season when temperatures are relatively cool, skies are clear, and humidity is low. It’s the ideal time for first-time visitors or those looking to cover all three countries in one Southeast Asia trip. This popularity comes at a price, however. Expect more crowds and higher hotel prices. It’s essential to book early, especially for cruises, hotels, and train tickets.

In Vietnam, Hanoi and Sapa are comfortably cool and perfect for walking tours and mountain trekking. Central Vietnam enjoys mild sunshine, making it a great time to explore Hue's imperial sites or relax on Hoi An’s beaches. Down south, the Mekong is calm, and Ho Chi Minh City is buzzing but not stifling.

Cambodia shines during these months. The Angkor temples near Siem Reap are easier to explore without heat exhaustion, and Phnom Penh's riverside comes alive with outdoor cafes and night markets. In Laos, Luang Prabang is refreshingly cool in the evenings, ideal for temple visits, night markets, and Mekong River Cruise.

March and October: Great Shoulder Season Months with Fewer Tourists

The shoulder seasons are for smart travelers. Planning a Vietnam Cambodia Lao tour itinerary during these months strikes a balance between avoiding peak season prices and tourist crowds, while still enjoying favorable weather.

March marks the end of the dry season in most areas. The temperatures begin to climb, especially in Cambodia and southern Laos, but the skies are still largely clear. It’s a wonderful time for beach trips, river journeys, and exploring ancient cities.

October, on the other hand, marks the beginning of the dry season. The rains taper off, leaving behind verdant landscapes, full rivers, and soft light that photographers love. It’s a particularly scenic time for countryside travel, with rice fields still green and forests fresh and alive.

April: Best Month for Festival Lovers in Vietnam, Cambodia, and Laos

April is one of the hottest months in the region, with daytime highs regularly above 35°C (95°F), particularly in Cambodia and Laos. But it’s still a top choice for culture lovers, thanks to the diverse festivals that mark the traditional New Year in both countries.

In Cambodia, Khmer New Year brings days of music, dance, and water fights. In Laos, Pi Mai celebrations are joyful and chaotic, with parades, flower offerings, and full streets. These are deeply cultural events where visitors are welcome to join the fun, just be ready to get soaked.

Vietnam’s biggest festival, Tet, happens earlier (usually January or February), but April still sees smaller regional celebrations and post-Tet festivities. Despite the heat, many travelers time their trip to coincide with these festivals, gaining unique insight into local customs and traditions.

Cambodia New Year is the most important festival in Cambodia.

May and September: Quiet and Affordable with Scenic Rewards

Traveling in May or September means embracing the transitional months of the wet season. Rain is possible, but it’s not relentless. Instead, you’ll often encounter dramatic skies, short showers, and spectacular scenery.

May marks the beginning of the rice planting season in northern Vietnam and Laos. Valleys transform into a bright green, and the terraced hillsides are mirror-like with new water. September is equally photogenic, as the rice turns golden before harvest.

These months are ideal for slow-paced travel. You’ll find great deals on hotels, tours, and transport for planning Vietnam Cambodia Laos tours on a budget. The crowds are gone, leaving temples peaceful and trails quiet.

Sapa is very beautiful with green terraced fields in May.

June to August: Lush Green Season with Local Summer Travel

June to August is the best time for nature lovers who enjoy rich, dramatic landscapes and don’t mind carrying a raincoat. Mornings are often sunny and clear, making it possible to explore cities or take short excursions before the rain sets in. The countryside is at its lushest, rivers run high, and waterfalls are spectacular.

Vietnam experiences a domestic tourism boom during this time, especially in July and August, when schools are on break. Popular destinations like Da Nang, Nha Trang, and Halong Bay can be crowded with local tourists. Cambodia and Laos, by contrast, are quieter during these months, with far fewer foreign visitors. It’s a great time to enjoy Angkor Wat or Luang Prabang without tour bus crowds.

Accommodation prices drop in many places, and spontaneous travel becomes easier. Just keep in mind that rural roads may be muddy, and some tours (especially hiking in Vietnam or boating in remote areas) may be suspended or altered due to weather conditions.

Travelers can enjoy hot airballon in Vang Vieng to see beautiful natural scenery in July.

Best Vietnam, Cambodia, Laos Tour Itineraries Based on Travel Season

If you’re planning a 14-day Vietnam Cambodia Laos tour in the peak season (November to February), a classic route would include Hanoi and Ha Long Bay in Vietnam, Luang Prabang in Laos, and Siem Reap in Cambodia.

This circuit combines UNESCO sites, river cruises, cultural cities, and mild weather. A 21-day journey could add Sapa or Ninh Binh in Vietnam, Si Phan Don (the 4,000 Islands) in Laos, and Phnom Penh or Kampot in Cambodia for a more in-depth experience.

In lower seasons like May or September, you might focus more on slow travel. Consider spending time in rural areas like Mai Chau or the Mekong Delta, or enjoying homestays along the Nam Ou River in Laos. Wet season doesn’t mean you have to cancel your plans; it simply invites you to explore at a different rhythm.

Regardless of the season, always pack a mix of lightweight clothing, rain protection, and one warm layer if you’re heading to the mountains. Sunscreen, insect repellent, and waterproof shoes are essentials. Visas for Vietnam Cambodia and Laos are convenient that can be obtained online and help to simplify border crossings.
