Best time to go to Laos for a perfect weather and where to go?
Julie Parment and Tony Samson last update: 16/04/2024When is the best time to go to Laos?
Due to heavy rainfall during the monsoon season, the best time to visit Laos is undoubtedly during the dry season: from October to April. During this period, temperatures are pleasant and rainfall is less frequent, allowing visitors to fully enjoy the beauty of this incredible country, for example by going on day hikes or multi-day treks.
In November and December, the peak tourist season is in full swing. Although prices remain stable, it is advisable to book your accommodations in advance to have a wider range of options. Although Laos is still relatively untouched by mass tourism, this period sees the highest number of visitors.
From January to March, the number of tourists decreases. When is the best time to visit Laos for only advantages? If you dream of pleasant weather while being able to visit tourist sites in peace, the ideal time to plan a trip is in April or October. So just before or just after the peak tourist season, avoiding the rainy season.
But if you appreciate authenticity, visiting Laos during the low season, which coincides with the rainy season between May and September, could be exciting. Due to low demand, flight prices are highest during this period, but it could be worth it if you have an adventurous spirit! Just make sure to prepare well to face the weather. In addition to a light and easily washable wardrobe, remember to pack a waterproof poncho in your suitcase, very useful in case of heavy downpours.

Climate and Weather in Laos
Laos is a landlocked country in Southeast Asia. It shares borders with Myanmar, Thailand, Vietnam, Cambodia, and China.
The climate in Laos has two variations:
- A tropical savanna climate with dry winters, predominant in the country and found in places like Vientiane, the capital, Houei Sai in the central part, and throughout southern Laos.
- A humid subtropical climate with dry winters and hot summers, more temperate, found in the northern mountains around Luang Prabang or Phonsavan.
Temperatures are fairly constant throughout the year, but are nevertheless higher in the south than in the north. It is generally hotter in Pakse than in Luang Prabang. Temperatures are also milder in the mountains than in the rest of the country. What marks the seasons and weather in Laos are the rainfall and humidity levels. As such, the country has two distinct periods:
The dry season in Laos
The dry season runs from October to April and the climate in Laos is more pleasant during this time. Temperatures are warm, rainfall is low, and humidity levels are very reasonable. There is virtually no rain from December to February. Arriving in Vientiane, the capital, will be a total climate change if you are coming from Paris or elsewhere in France, where winter is in full swing!
This season will have some variations depending on where you are:
- In the north, around Luang Prabang, it lasts until May, with March being an ideal month to visit the region as it has the least rainfall. However, be aware of cool nights in the mountains. Due to temperature variations based on altitude, the temperature drop from day to night is significant, with minimums dropping below 10°C (50°F) .
- In the central region, midday heat is more intense than elsewhere. Expect maximum temperatures approaching 40°C (104°F) ! However, this is where it rains the most during the dry season, which is perfect for cooling the atmosphere.
- In the south, the dry season is shorter, from November to April, but it is well defined with perfect months to explore the area between November and February. March and April already see significant rainfall, as a precursor to the upcoming rainy season.
The rainy season in Laos
From May to September, the weather in Laos is hot and humid, as the rainy season hits the country brought by monsoon winds. Temperatures are lower than usual, but rainfall is very significant, and the air, laden with humidity, becomes stifling.
The months of July and August are usually the most affected by torrential rains. In some regions, especially in southern Laos, there is little respite, and rain-free days are extremely rare during this period.
In the north, showers are less frequent and less intense. Therefore, traveling during the monsoon season is still possible. For example, in Vientiane, it rarely rains during the day, with the first showers arriving in the evening and continuing for much of the night. This allows for enjoyable walks without too many weather-related constraints.
