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.

Festivals and Events

The people of Laos love a good celebration and there are plenty of reasons to put on a festival with a calendar of events that mark the agricultural seasons or to honour important dates linked to the life of Buddha. Here's a selection of our favourites.

What is the Lao Food Festival?

Run by the Lao Women's Union and Lao Businesswomen's Association, this festival is in its eleventh year and brings together traditional Lao cuisine for everyone to try. It's held in Vientiane over the course of three days in January.

What is the Boun Ma Kha Bu Saar (Full Moon) Festival?

Celebrated in temples and Wats across the country with the biggest celebrations taking place at the Khmer ruins of Vat Phu Champasack, this festival marks the day when Buddha delivered a speech to some 1,250 monks with chanting, candles and processions.

What is the Boun Pi Mai (New Year) Festival?

This is one of the most important celebrations in Laos with three days dedicated as a public holiday during which families get together to clean out their homes, provide offerings to local temples and decorate images of Buddha with flowers. Like Songkran in Thailand, it's a time for frivolity with friendly water fights held on the streets.

What is Boun Bang Fai?

Held between April and June each year, this loud and boisterous celebration invites people across Laos to set off handmade rockets designed to herald in the rains for the forthcoming harvest. Music and dance performances accompany the main event alongside colourful processions in the larger towns and cities.

What is Boun Khao Padabdin?

Laos' version of the Day of the Dead, every September families across the country honour dead relatives and ancestors with offerings of rice and over foods. For visitors, a highlight of the festival is the handmade boats that are raced along the Mekong River in conjunction with Boun Khao Padabdin.

What is Boun Ok Phansa?

This festival honours the Buddhist monks that have spent the last three months fasting for lent with offerings of food presented to local temples. It's a stunning time to visit with flowers and candles set adrift on rivers to symbolise the letting go of bad luck.

What is the That Luang Festival?

During the full moon of the twelfth lunar month (November) thousands of monks and pilgrims descend on the gold-covered Grand Stupa (Pha That Luang) in Vientiane. Bearing candles and floral votives, it's a particularly joyous time to visit though accommodation and other services book up quickly.
