Temperature, rainfall and humidity at a glance
Is May Right for You?
Weigh the advantages and considerations before booking
- + Hotel rates drop 25-35% compared to December-February peak season, with vientiane hotels offering same-day availability at most 3-star and boutique properties
- + Morning light photography is spectacular - the sun rises at 5:45 AM, casting golden light over the Mekong at That Luang while humidity stays comfortable until 9 AM
- + Riverfront restaurants along Rue Setthathilath serve the best laap and grilled pa beuk (Mekong giant catfish) of the year - the fish runs peak in May before monsoon season
- + Evening cycling along the Mekong promenade becomes magical after 6 PM when temperatures drop to 28°C (82°F) and locals set up impromptu food stalls along the river
- − Afternoon heat peaks at 35°C (95°F) with 70% humidity from 11 AM to 4 PM - the kind that makes temple steps feel like hot plates and turns the Patuxai monument into a heat trap
- − Sudden thunderstorms roll in around 3 PM most days, dropping 230 mm (9.1 inches) total - these aren't gentle showers but 30-minute downpours that flood side streets and make tuk-tuk rides feel like waterslides
- − Outdoor markets like the Morning Market (Talat Sao) become steam chambers by 10 AM, with vendors napping between stalls and the usual maze of fabric vendors thinning out by noon

How May compares to the rest of the year
Best Activities in May
Top things to do during your visit
May evenings on the Mekong deliver the perfect combination - 28°C (82°F) breezes, dramatic cloud formations from afternoon storms, and empty river traffic. The 90-minute cruises leave from the main pier at 5 PM, timing the golden hour well while avoiding midday heat. Locals prefer these evening runs because the river water is warm enough for swimming but cool enough to refresh.
The 200+ Buddhist and Hindu sculptures at Buddha Park photograph best at 6:30 AM in May - the 24°C (75°F) morning temperature makes the 25 km (15.5 mile) drive from city center tolerable, and the soft light brings out the patina on the 40 m (131 ft) reclining Buddha. Crowds are non-existent before 8 AM, when tour buses start arriving from Thailand.
May's afternoon heat makes indoor activities essential - family-run textile workshops in Ban Nongduang Tai village offer air-conditioned spaces where you can learn silk weaving techniques passed down through three generations. The workshops run 1-4 PM daily, well timed to escape the worst heat while learning about Lao textiles.
The night market comes alive after 6 PM when temperatures drop - this is when locals emerge for sticky rice with fermented fish sauce, grilled Mekong seaweed, and Beerlao served at plastic tables. The market stretches 500 m (0.3 miles) along Khoun Boulom Road, with vendors specializing in regional specialties from Luang Prabang and southern Laos.
6-9 AM cycling tours hit five temples including Wat Si Saket and Wat Ho Phra Keo while temperatures stay under 28°C (82°F). The 12 km (7.5 mile) route follows quiet side streets where monks collect alms and morning markets sell fresh baguettes and Lao coffee. May's light tourist traffic means you'll often have temple courtyards to yourself.
May Events & Festivals
What's happening during your visit
Villages outside Vientiane launch homemade bamboo rockets to encourage rainfall - the festival involves traditional Lao music, fermented rice wine, and rockets that sometimes explode spectacularly off-course. The main celebrations happen in nearby Ban Keun village, 60 km (37 miles) north.
