Laos Guide
Weather
November to February are the most pleasant months to travel in lowland Laos, when daytime temperatures are agreeably warm and evenings slightly chilly; at higher elevations, temperatures can drop to freezing point. In March, temperatures begin to climb, peaking in April, when the lowlands are baking hot and humid. The rains begin in May and last until September, rendering many of Laos's unsealed roads impassable.
