The small, landlocked country of Laos is best visited between October and April, when the weather’s warm and dry throughout. River travel is best between November and January, when high water levels make passage easy along Laos' main waterway, the Mekong River. Visiting the Bolaven Plateau is also pleasant at this time of year. Laos’ geography plays a major part in shaping its climate, and cool temperatures can still be found in the highlands, which lie mainly in northern, eastern and central regions. The 'green season’ falls between late May and October, when the rains return to the country. However, showers are usually short and sharp, having little impact on your exploration. At this time of year the country comes to life, with waterfalls beginning to flow once more and the lush scenery attracting a variety of wildlife.

October is a great time to travel to Laos as the dry weather returns and you can take advantage of shoulder season deals. It also presents excellent conditions for river travel. For trekking, the cooler months of December and January are better.

Visiting Laos in August

Rainfall reaches its peak in August as showers become longer and more intense, and little of the country will remain dry. River levels begin to fill up in time for the dry season approaching, and Laos' beautiful landscapes return. During this time, travel to remote areas can be somewhat difficult. Temperatures drop to the low 20°Cs throughout the country.
