Cambodia Weather & Climate Guide 2026

The weather calendar for Cambodia: season by season, with the trade-offs each month brings.

Cambodia captivates visitors with the magnificent Angkor Wat temple complex, French colonial architecture, and pristine tropical beaches. From the bustling capital of Phnom Penh to the serene countryside, Cambodia offers an unforgettable blend of ancient history, vibrant culture, and warm hospitality.

Cambodia has a tropical monsoon climate with two distinct seasons: a dry season from November to April and a wet season from May to October. Temperatures are warm year-round, ranging from 22°C (72°F) in cooler dry-season nights to 38°C (100°F) during April's hot season. The wet season brings heavy afternoon rains that flood the Tonlé Sap Lake to six times its dry-season size and turn the Angkor jungle vivid green.
