Cambodia is a country famed for its fascinating history, rich culture and stunning natural beauty. Found in Southeast Asia and bordered by Thailand, Laos and Vietnam, it boasts a tropical climate with two distinct seasons: the rainy season, between May and November, and the dry season, from December to April. Due to the country's low altitudes, rainfall during the wet season significantly increases the water level of Cambodia's lakes and rivers. Showers are usually heavy but short and mainly occur in the afternoon or at night, following a day of sunshine. Generally, the best time to visit Cambodia is between November and March (during the dry winter season) to avoid the rains and extreme heat. The wet season offers benefits, too, including affordable rates, fewer crowds and lusher landscapes. Want to know more? Read on to discover our month-by-month breakdown.
Overview of Cambodia’s weather
Two monsoons make up Cambodia's climate. The southwest monsoon brings heavy rainfall and strong winds from May to November, with temperatures ranging from 27°C to 35°C. Cambodia's dry season, courtesy of the northeast monsoon, runs from December until April. This monsoon has two seasons: the first stretches from November until February, when it's cooler, at around 17°C, and the second is between March and April, when temperatures are between 29°C and 38°C.
The dry season varies depending on the region, with southern Cambodia enjoying a two-month dry season and the north boasting a four-month dry season. Mild, dry winds blow from the Central Asian landmass this season, creating sunshine and pleasant temperatures, perfect for enjoying the scenery and soaking up Cambodia's culture.
Rainfall also depends on the region in Cambodia. During the dry season, the humidity level is 50% during the day (sometimes lower) and 60% during the wet season.
Angkor
The ancient city of Angkor is one of Southeast Asia's most important archaeological sites. Located in northwest Cambodia, it has a dry (and very sunny) season from November to April.
Phnom Penh
Phnom Penh is the capital of Cambodia, located on the banks of the Mekong. Like Angkor, visiting this city between November and March is best. There is less rainfall, and temperatures are more comfortable, between 23°C and 32°C. During the monsoon, in the height of the wet season, rainfall can be about eight inches. We recommend exploring the capital in January, the driest month when temperatures are also very pleasant, with an average of 26°C. For those in search of scorching temperatures, April is the hottest month.
Sihanoukville
With a string of beautiful beaches along its entire coastline, Sihanoukville is a popular city in the southwest of Cambodia, bordered by the Gulf of Thailand. The coastal city has a tropical climate, with heavy rainfall throughout most of the year. Average temperatures hover around 28°C. Although there's generally less rainfall from December to April, we recommend February, the driest month, as the best time to visit this popular beach resort.
Eastern Cambodia
Eastern Cambodia is still relatively undiscovered by tourists. However, the climate is cooler than the rest of Cambodia, so we strongly recommend packing lots of warm layers to explore this part of the country. During the rainy season, the dirt roads leading to this region become muddy and impassable. So it's best to visit during the dry season when the roads are at their best. November is the best time to visit the Mondulkiri region, as the landscape is very green and luscious, but the rainy season is ending.
