Best Time to Visit Laos: Weather and Festivals Guide

Laidback Laos has a climate to match. With no coastline to stir up troublesome storms, the country’s weather system is pretty simple.

There’s a wet season (May to late September) and a dry season (October to late April).

Outside of that, altitude and latitude generally exert the strongest influences: the higher you are or the further north you are during the dry season, the cooler you’ll be.

Weather in Laos throughout the year

January – February

January and February are lovely times to visit, with dry conditions throughout the country. Main cities should be in the comfortable mid-twenties; the lower-lying parts of the south are nearer to 30°C. Bring warm layers if you’re heading to the north or high altitudes, as it can get cold at night.

March – April

As March and April roll around, Laos starts to heat up. Across the entire country, the temperatures rise and it becomes dry. Almost mimicking the weather, farmers will start the “slash and burn” practice – an agricultural technique involving burning the remaining leaves and plant life leftover from the harvest. Festivals and celebrations also begin to heat up as well. Lao New Year, known as Boun Pi Mai Lao or the water festival, is an exhilarating celebration. Everyone is invited to participate in the lively water festivities, but be ready to get thoroughly soaked if you decide to join in!

May – September

In Laos’s wet, or green, season; the rain brings the return of lush landscapes countrywide. It’s still hot and humid, especially in the south. Showers, while heavy, don’t last all day, so this remains a great time to travel, especially if you’d like to see Laos’ stunning scenery at its peak.

October

Come October, the weather in Laos transforms; the rains gradually ease off and the dry season approaches. This period is enchanting throughout the entire country, and whilst there is a small chance of showers and temperatures are slightly cooler than other months, it is still far from cold with temperatures averaging 24-26°C.

November

The dry season is back by November in Laos, which makes this a brilliant time to explore. The rains have passed, leaving astonishingly verdant rural areas, but rivers are still running high, making this an ideal month for boat trips. Expect pleasantly warm temperatures, except in the cooler Northern Highlands.

December

In December, the weather in Laos is excellent, with minimal rain and lots of sunshine. The temperatures across the country are generally at their lowest, and it can get quite chilly at night when at altitude or in the north, but otherwise it’s a very popular month for travel.

When is the Best Time to Visit Laos?

To put it simply, the best time to visit Laos is between November and March. During these months you are most likely to experience dry and warm weather. In October, temperatures sit around a comfortable 25°C. It can become cool during the UK’s winter months, particularly at altitude or as you go further north. As it moves into the spring, the temperature starts to rise, and by March and April, it is hot and dry throughout the country, with temperatures averaging 30°C around Luang Prabang and up to 40°C in the south. Bear in mind that at this time, the burning of the fields and lower water levels can make the countryside less attractive.

With warm, temperate weather and rains generally restricted to short, sharp showers, the wet season in Laos (or green season, as it is known locally) does not necessarily mean that you should avoid travel. Many people argue that September to November is the best time to visit Laos, with the beautiful landscape lush and the rivers and waterways awash with monsoon rains.

In short, travel throughout the year can work well, but if you are planning a luxury holiday to Laos and have flexibility, it is worth thinking about the pros and cons of each period and what is best suited to you.

‘Beach’ Season in and around Laos

With no coastline, there are no sea beaches in Laos, but that does not mean there are no options when it comes to a relaxing end to your holiday. In the South, there is a range of hotels on the banks of the Mekong, including some that have their own sandy beaches. This area has been dubbed the 4,000 islands for its impressive beauty. The best time to visit these riverside hotels is during the dry season.

For those looking for a more traditional beach stop, there are options throughout the year across Southeast Asia. The beaches and islands of Thailand, Vietnam and Cambodia work throughout the dry season, while central Vietnam, Malaysia and the Indonesian islands off of Singapore work well throughout the summer.

Key Dates & Festivals in Laos

Laos is home to many ethnic groups and has a range of festivals to match, although the biggest event is Boun Pi Mai Lao (the water festival) which takes place in mid-April to celebrate Laos New Year. Officially lasting three days, the festivities often continue for a full week and along with parades, expect to see huge water fights in the streets. Everyone is welcome to join in, but do expect to get very wet!

Other festivals include Boun Bung Fai, which sees locals fire homemade rockets into the air to ask the spirits to end the hot season (around May or June) and bring on the rains. Later in the year, usually around October, there are also boat races on the Mekong around Vat Phou and parades to mark the end of Buddhist Lent.
