Vientiane Weather

Travel and Local Information Guide

Vientiane has a tropical climate with a dry season and a wet season typical of Laos and its neighbouring countries. Temperatures range from warm to hot, with some very humid days when the rains mark the start of the southwest monsoon season in May or June. Rainy conditions continue through to the end of October, then the northeast monsoon arrives bringing with it drier and cooler days.

November through February feature the most comfortable, sunny days in Vientiane, then the temperatures rise in March, April and May.

Best Time to Come

The best time to visit Vientiane is during the cooler months of November to March, though it is also the peak tourist season so prices may be higher and the sites may have more visitors. Vientiane rarely feels, crowded however. If visiting in April expect some hot, sticky days but it's also a good chance to see how the locals cool down with their New Year's water festival. Similar to the famed Songkran festival in neighbouring Thailand, the Vientiane version is much more low-key though equally enjoyable.
