Cambodia is one of Southeast Asia’s most rewarding destinations — home to the ancient temples of Angkor Wat, tropical islands, vibrant cities, and lush countryside shaped by the Mekong River. But choosing the best time to visit Cambodia can completely change your travel experience.

The country has a tropical monsoon climate with two distinct seasons: dry season and rainy season. In general, the best time to travel to Cambodia is between November and February, when temperatures are cooler, humidity is lower, and rainfall is minimal.

Still, every month offers something different — from green rice fields during monsoon season to perfect beach weather along Cambodia’s southern coast. Here’s a complete month-by-month Cambodia weather guide to help you plan the ideal trip.

Cambodia Weather Overview

Cambodia experiences two main seasons:

• Dry Season (November to April) — Sunny skies, low rainfall, ideal for sightseeing and beaches.
• Rainy Season (May to October) — Tropical rains, greener landscapes, fewer tourists, lower prices.

Average temperatures range between 25°C and 35°C year-round, with April usually being the hottest month.

But Cambodia is truly a year-round destination. The rainy season offers fewer tourists, greener landscapes, and a more authentic travel experience — especially for photographers and slow travelers.
