Seasons and Weather
Generally speaking Laos has two distinct seasons - the dry season between October and April, and the wet season from May to September. However, given the varying altitude of the country, the temperatures during these times can vary quite considerably. As a land-locked country, Laos benefits from a simpler weather system than other parts of Southeast Asia. Overall November through to April are the best months to travel to Laos, when the weather is warm and dry and the nights are comfortably cool. Temperatures typically begin to rise around March and the rain hits in May or June. From June through to August, the humidity can soar and short tropical downpours are common. September and October can still bring the occasional shower.
The start of the dry season (October) is a great time to visit Laos. The countryside is still lush and green, the temperatures aren’t too high (24 – 26°c) and the rains begin to ease off. From November through to February the river levels are still quite high and the temperature is on the up. However, be prepared for the evenings to be quite chilly in some places especially in the north and highlands of Laos. March and April see some of the warmest temperatures in Laos (30 – 34°c) being the end of the dry season, plus it is the start of the farmer’s ‘slash and burn’ practice where they dispose of all the remaining plant life from the harvest in time for the impending wet season.
The annual wet season in Laos starts in May and lasts until September. Like many other Southeast Asian countries the daily down pours can be short and sharp but rarely stay around all day. Temperatures are still quite high (30°c+) but with the frequent deluges, the countryside transforms into a beautiful verdant wonderland and the dry spells bring clear blue skies, so it can be a picture perfect time to visit Laos.
