Climate of Cambodia
Country climate guideCambodia is a low-lying country wrapped around the Great Lake, where the Tonle Sap floods each year into the rice fields and drains them just as regularly. Monsoon winds decide its year, sending wet air up from the south-west in summer and dry air from the north-east in winter. The flat, low interior means there is little to slow a storm or a blast of heat.
Main climate types
The whole country is classed as tropical wet, marked by a strong dry season rather than a cold one. The south-west monsoon, crossing the Gulf of Thailand and picking up what moisture there is to give, delivers nearly all the rain from May to October. A north-east monsoon in winter brings cooler, drier air. The Cardamom mountains in the west squeeze more rain from the system, and the plains along the Mekong flood when the monsoon peaks.
Temperatures
Phnom Penh averages about 26 °C from December through February and climbs to near 29 °C in April, usually the hottest and least comfortable month. From May the monsoon breaks the heat, and daily highs during the wet season settle in the upper 20s. Lows in the 13 °C to 15 °C range are normal in the hill districts at the end of the dry season. Snow has never been recorded anywhere in the country.
Rainfall
Phnom Penh receives about 1,500 mm a year, but the distribution is extreme: roughly four-fifths of it falls between May and October, and December and January together get very little. The coastal province of Kampot and the slopes of the Cardamoms are the wettest parts of the country, exceeding 2,000 mm, while the eastern borderlands towards Vietnam are markedly drier, sometimes below 1,000 mm.
When to go
The dry season, from November to April, is the obvious choice: lower humidity, milder nights and easier movement around the temples of Angkor. April is the hottest point, and late May the first heavy rains. Between the monsoon months the countryside is verdant and the lake is at its fullest. The weather is best in the cool months of December and January, when mornings are crisp and the sun is strong until late afternoon.
