The wet season is in full swing throughout Laos in June, although showers tend to be short and intense, lasting for a few hours rather than all-day downpours.
Generally speaking, the rainfall is heavier the higher you are; with the riverside towns south of Vientiane experiencing the least rain. The return of the rains means the countryside is becoming more lush and green, especially around Vang Vieng, and the impressive waterfalls in the 4000 Islands come to life again.
Average temperatures hover around 25-27°C, with Pakse experiencing warmer temperatures than Luang Prabang and Vientiane, and slightly cooler conditions in Phongsali in the north. Humidity levels in June edge up to 80%.
