Weather & climate Laos

Best time to visit:
Throughout the country, the climate is hot and tropical, with the rainy season between May and October when temperatures are at their highest, up to 35°C. The weather is very similar to that of northern Vietnam. The dry season runs from November to April, which is the best time to visit as the temperature is at its most comfortable. However, the mountainous areas can be very cold at this time, down to around 5°C. Across Asia the annual monsoon is becoming ever more difficult to predict, possibly as a result of global warming. This plays havoc with farming and occasionally travel plans too. As a guide, the average rainfall in the capital Vientiane is about 1,700 mm, although in the north of Laos and the highlands it is far wetter, with more than 3,000 mm each year.
Required clothing:
Lightweights and rainwear, with warmer layers from October to March and for upland areas. If you come during the monsoon summer months, bring lightweight waterproofs, an umbrella and some leech oil for trekking. Bring a swimming costume for hotel swimming pools too.
