In Laos, the Awk Phansaa (Awk Watsa, full moon) Festival celebrates the end of the three-month rains retreat. Monks are allowed to leave the monasteries to travel and are presented with robes, alms bowls and other requisites of the renunciative life.

On the eve of Awk Phansaa many people fashion small banana-leaf boats carrying candles, incense and other offerings, and float them in rivers, a custom known as Lai Hua Fai, similar to Loy Krathong in Thailand.

A second festival held in association with Awk Phansaa is Bun Nam (water festival). Boat races (suang heua) are commonly held in towns located on rivers, such as Vientiane, Luang Prabang and Savannakhet.
