Laos in June

Our take: fair

The rainy season settles in: 23 rainy days on average in Luang Prabang, more than 300 mm in the month in Vientiane and Pakse. It's the quietest month of the year: in 2024, Laos had five times fewer long-haul visitors in June than in December.

The Mekong in Laos in June

June opens the flood season, which lasts until November and carries 70 to 80% of the river's annual flow, according to the Mekong River Commission. The level starts to rise; the sharp increase comes in July.

Typhoons
The Asian typhoon season runs from June to November: follow weather alerts.
