April in Luang Prabang is high
April is high for Luang Prabang.
WARNING: April brings the haze tail + Pi Mai Lao (Lao New Year April 13-16) + year's hottest month all stacked together. Days 34°C / 93°F + nights 22°C / 72°F + rainfall climbs to 100mm as monsoon onset begins late month.
Pi Mai Lao (April 13-16) is Luang Prabang's biggest annual celebration — Sisavangvong Road, Wat Xieng Thong, and the entire UNESCO zone become a 4-day water battle + scented-water-pouring + monk-foot-washing ritual.
