Overview of Weather in Cambodia
Cambodia’s climate is refreshingly straightforward, shaped by two distinct seasons, making it easy to plan your trip no matter what kind of adventure you’re seeking.
- Dry Season (November to April): This is the golden window for travel with its clear blue skies, low humidity, and pleasantly warm days (typically mid-20s °C). From November through February, you’ll experience the most comfortable weather, ideal for temple runs, city strolls, and Mekong or coastal escapes
- Green Season (May to October): The southwest monsoon brings revitalizing rain, often in the form of short, dramatic afternoon showers. These rains transform the landscape into a vivid green, swell rivers and Tonlé Sap, and make rural Cambodia breathtakingly lush, albeit with higher humidity and fewer crowds.
Annual temperatures hover between 24 °C and 32 °C, with March and April bringing the most intense heat, often reaching 35 °C or higher. The coolest period lands in the December–January range, offering refreshing relief and perfect sightseeing conditions.

April – Khmer New Year & Tropical Heat
