The best time to visit Cambodia depends on the heat, rainfall and number of tourists. Most travelers visit Cambodia from November to March. If you prefer to dodge the crowds and go when prices are lower, the best time to visit Cambodia is from May to early October.
Cambodia is warm year-round with temperatures rarely dipping below 68°F (20°C), wherever you go. Seasons are broken into wet and dry season. Wet season, from May to October, is usually marked by a brief downpour in the afternoon. This rarely affects travel plans and still includes many hours of bright sunshine. It is known locally as green season as the countryside springs to life. Travel in the dry season, from November to March, is marked by hot dry days.
Dry season temperatures, from November to April, range from a 68°F (20°C) minimum to highs in the 80s (high 20s), with maximums reaching 95°F (35°C) in March. Humidity remains around 74% and rainfall is minimal so roads can be a little dusty, while the leafy areas around the temples are easier to traverse. This is a busy time of year to travel, so some sites and temples can be crowded.
April and May are hot with humidity around 85%, and it is not uncommon for temperatures to reach above 100°F (38°C). The green season from May to October is the best time for seeing full moats around the temples of Angkor, dramatic skies and verdant rice-paddies. Minimum temperatures are around 75°F (24°C) and maximums start to drop from May and stay around 90°F (32°C) for the rest of the season. Rain is tropical in Cambodia with refreshing afternoon downpours.
Tonle Sap Lake – South East Asia’s largest – fills during the green season and, while touring is possible year-round, water levels can affect which parts of the lake you may visit. The best time to go is between July and December.
Battambang has the same wet and dry seasons as nearby Siem Reap. If planning on traveling by unpaved roads, avoid September and October as heavy rains can cause delays.
Cambodia’s capital is warm year-round with tropical rains from May to October, and hotter, drier days from November to April. In the green season from May to October, temperatures range from lows of 71°F (22°C) to highs of 93°F (34°C) in May. From November to April lows rise to 77°F (25°C) with highs around the low 90s (low to mid 30s), and rainfall peaks during September and October. The best time to go is November to February when temperatures and rainfall are lowest.
