The climate guide for Laos (Vientiane) shows long term monthly weather averages processed from data supplied by CRU (University of East Anglia), the Met Office & the Netherlands Meteorological Institute. Find out more about our data sources.
Laos climate overview
Laos is a hilly, landlocked country with jungle covering more than 60 per cent of its surface. It has a single rainy season (May to October) and a dry, sunny climate, averaging 8 hours of daily sunshine for the rest of the year.
What to pack for Laos
In low-lying areas, light clothing is fine whatever the time of year, but be prepared for the monsoon rains. Winter conditions are chillier up in the mountains, especially when cloudy fronts blow in from China, so take warmer clothing if you are planning to go high up.
