Best time to visit Vientiane

The best time to visit Vientiane is from November through March. Note that these months are when the Lao capital receives a large tourist crowd. Flight and hotel prices are highest during this time of the year, but you’ll be able to enjoy cooler weather while sightseeing in Vientiane.

If you’re 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 Thailand, the Vientiane version is much more low-key, but it’s equally enjoyable (and less packed with overenthusiastic tourists).
