The best time to visit Laos is November to February, when skies are at their clearest and temperatures stay comfortable. Laos in March is a different story. Days turn hot, and smoke from seasonal field burning can haze the north. Even so, March can work well with smart planning. This guide covers Laos weather, places to visit in Laos, and practical tips for families with children and older travellers.
Quick answer: March is a workable but not ideal month for Laos. Expect highs of 30–34°C (86–93°F), almost no rain, and hazy skies in the north. Smoke is usually heavier in the north, while the south runs hotter, so pair southern Laos with the cooler Bolaven Plateau. Families and seniors should plan around air quality and the midday heat.
When is the best time to visit Laos?
Laos has three travel seasons, and each suits a different kind of trip. The table below summarises them, so you can see where March fits.
| Season | Months | What to expect | Best for |
|---|---|---|---|
| Cool and dry | November–February | Warm days, cooler northern nights, mostly clear skies | Sightseeing, river travel, trekking |
| Hot and dry | March–April | Hot days, little rain, haze in the north | Southern Laos, village festivals, Lao New Year |
| Green (wet) | May–October | Humid weather, showers, lush scenery | Waterfalls, quieter trails, October trips |
Most specialists agree that November to February is the sweet spot. November to January is the strongest window for Mekong river travel, because water levels are highest. However, those months are also high season, so expect heavier crowds and higher prices.
Haze can start to build from December, so check air quality even in the cool season. October is a good shoulder month. Rains ease, the countryside stays green, and crowds remain light.
What is the weather in Laos in March?
Laos weather in March is hot and dry across the country. However, conditions vary by region, so your route matters.
| Destination | Typical daytime temperature | Average rain | What it feels like |
|---|---|---|---|
| Luang Prabang | 33°C / 91°F | about 25 mm | Hot afternoons, possible haze |
| Vientiane | 33°C / 91°F | about 25 mm | Hot, so air conditioning is essential |
| Vang Vieng | 32°C / 90°F | about 50 mm | Hot, and often hazy |
| Nong Khiaw | 30°C / 86°F | about 25 mm | Warm, with cooler hill mornings |
| Champasak (south) | 34°C / 93°F | about 25 mm | The hottest of the five |
Figures are approximate climate averages, converted from Fahrenheit.
Rain is rare in March. As a result, you can plan outdoor days with confidence. Mornings are the only truly comfortable window, though. Therefore, start sightseeing by 7:30 am and rest indoors from midday to mid-afternoon.
Is Laos too smoky to visit in March?
Smoke is the biggest unknown for Laos in March, so it deserves a clear answer. In short, haze can affect any region in March, though the north is usually hit hardest.
The cause is seasonal burning. In particular, farmers clear fields to prepare for the new planting season, and forest fires add to the smoke. The World Health Organization says fine-particle pollution in Laos typically peaks in March and April, after building from December.
The government ordered a nationwide ban on outdoor burning from January to April for the 2025–26 dry season. Even so, IQAir readings in January 2026 reached 203 in Vientiane and 152 in Luang Prabang. In the north, smoke can linger until the rains arrive in May.
Conditions also change from year to year. In 2023, an unusually long burning season pushed readings into the hazardous range across Laos in late March and early April. Some tourists might cancelled their plans because of it. Consequently, flexibility is more valuable than any fixed itinerary.
How can you plan around the haze?
Four simple habits protect your trip, and they cost very little.
- Check the air before you commit. Watch live readings on IQAir or a similar app from a week out. Readings above 100 on the US AQI scale are flagged as unhealthy for sensitive groups.
- Keep a swap plan ready. Hold a southern or indoor alternative, so a smoky day never wastes a booking.
- Pack basic protection. Bring N95 or KN95 masks, eye drops, and a refillable water bottle.
- Choose air-conditioned rooms and vehicles. Closed windows make evenings far easier on the lungs.

What are the best places to visit in Laos in March?
The best places to visit in Laos in March offer shade, water, or altitude. Below, we list our top picks, with the reason each one works in the hot season.
What should you see in Luang Prabang in March?
Luang Prabang remains the heart of any Laos trip, even in the hot season. Its old town is compact and tree-shaded, so short, early outings work well. That said, it sits in the northern burning zone, so check the air before you go.
- Dawn alms-giving ceremony: Monks walk the streets at sunrise, when the air is coolest. Watch quietly from a respectful distance.
- Wat Xieng Thong and the Royal Palace Museum: Visit both before noon. Cool temple halls and courtyards soften the heat.
- Kuang Si Falls: Turquoise pools sit beneath forest shade, about 45 minutes by car from town. Water flow is gentler than in the green season, yet the pools remain a highlight. A bear rescue centre at the entrance adds an easy stop for children.
- Pak Ou Caves: Two riverside caves, about 25 km upstream, hold thousands of Buddha statues. The boat ride brings a welcome breeze. Bring a phone torch for the dark upper cave.
- Mount Phousi at sunset: Climb only when the air is clear. Haze can dull the view, and the steps are steep in the heat.
Best for: first-time visitors, families, and seniors who prefer short transfers. For route options, see our guide to travelling from Huay Xai to Luang Prabang.
What should you see in Vientiane in March?
Vientiane suits the hottest days because several top sights are shaded or indoors. It is also the railway gateway to Luang Prabang.
- Pha That Luang: This golden stupa is a national symbol of Laos. Visit early, before the heat builds.
- COPE Visitor Centre: This free indoor exhibition explains the legacy of unexploded ordnance in Laos. It is moving and sobering, so it suits older children and teens best.
Best for: seniors, culture lovers, and anyone who needs an indoor option on a hazy day.

Is Champasak and Wat Phou worth visiting in March?
Yes, but start at dawn, because southern Laos runs hotter than the north. Smoke can still reach the south, so check the air there too.
- Wat Phou: This UNESCO-listed Khmer temple complex rises in terraces toward a mountain sanctuary. The site involves steps, so pace yourself and arrive at opening time.
- Riverside Champasak: The Mekong town makes a calm base after a morning at the temple.
Best for: history lovers and early risers.
Why add the Bolaven Plateau to a March trip?
Higher altitude brings relief from the heat, which is why we pair the plateau with southern Laos.
- Tad Fane Waterfall: This dramatic waterfall sits on the plateau. Flow is lighter in the dry season, yet the setting stays cooler than the lowlands.
- Coffee plantations: The plateau is known for coffee, and farm visits make relaxed, shaded stops.
Best for: families and seniors who want cooler air.
Which areas should you skip in March?
Trekking and viewpoints depend on clear air. Northern areas such as Vang Vieng, Nong Khiaw, and Luang Namtha see more burning than the south, so views there often turn hazy. Consider postponing northern treks and viewpoint climbs. Instead, save them for a trip outside the burning season.
What festivals happen in Laos in March?
Festivals add colour to Laos in March, especially in rural areas. Two are worth knowing. Boun Koun Khao is an agricultural harvest festival held in villages and temples. Boun Pha Vet, held in late March, is a three-day religious festival recalling a past life of the Buddha.
Both festivals offer a genuine window into village life. However, dates follow the lunar calendar, so confirm them close to departure. Lao New Year, or Pi Mai, follows in mid-April with water-splashing celebrations. Hotels fill up and rates peak then, so book early if you hope to join.
Is Laos in March suitable for families with kids and seniors?
Yes, provided you adapt the pace. Our team builds March itineraries around three rules: early starts, cool afternoons, and flexible backup plans.
What tips help families with young children?
Children tire quickly in 33°C heat, so small changes make a big difference.
- Start early, finish early. Schedule outings between 7:30 and 11:00 am, then head back for lunch and a rest.
- Choose a hotel with a pool. An afternoon swim turns the hottest hours into a highlight.
- Pick water-friendly sights. Kuang Si Falls has shaded pools, and its bear rescue centre adds an easy, shaded stop.
- Keep drives short. Break long road journeys into stops, or take the train.
- Pack smartly. Bring hats, high-SPF sunscreen, and electrolyte sachets. Ask your paediatrician about masks for young children.
What should seniors know before travelling?
Heat and haze affect older travellers sooner, so comfort should drive every choice.
- Plan a long midday break. Return to an air-conditioned room between noon and 3:00 pm.
- Skip the steepest climbs. Enjoy the Mekong sunset from a riverside terrace instead of the Mount Phousi steps.
- Take the train, not the road. The air-conditioned Laos–China Railway links Vientiane and Luang Prabang in about two hours. The same trip by road takes six hours or more, and stations sit outside town, so a private transfer helps.
- Avoid the public slow boat. Low water and haze make the two-day journey less pleasant in March, and facilities are basic.
- Speak to your doctor first. If you have heart or lung conditions, check before booking, and carry medication in your cabin bag.
A private tour and driver make all of this easier, because you control the pace.
Should you choose March or another month for Laos?
Your priorities decide the answer. The table below helps you compare.
| Choose March if… | Choose another month if… |
|---|---|
| Your school or work dates are fixed in March | Anyone has breathing or heart concerns (go October or November) |
| You want to pair southern Laos with the Bolaven Plateau | You want a Mekong cruise at high water (go November–January) |
| You hope to see village festivals such as Boun Pha Vet | You want clear photos and mountain views (go November–February) |
| You can adjust plans if air quality drops | You want lush waterfalls and green scenery (go October or November) |
How can a private tour make Laos in March easier?

Prices are starting rates per person and vary by season and group size.
Prefer a gentler pairing? Southern Vietnam makes an easy add-on before or after Laos. Start with our Mekong Delta travel guide, then consider this private tour:
