Climate Overview
Laos has a tropical monsoon climate with two distinct seasons. The dry season (November to April) brings clear skies, lower humidity, and cooler temperatures making it the ideal travel period. The wet season (May to October) brings heavy monsoon rains that make roads impassable but fill waterfalls to their spectacular peak. The north experiences cooler winters (December-January can drop to 10-15°C at night in Luang Prabang) while the south remains hot year-round. March to May is extremely hot, often exceeding 38°C in the Mekong lowlands.
