Weather in Phnom Penh
Located in the tropical zone north of the equator, Phnom Penh has a wet and dry climate, meaning it has two distinct seasons: rainy and dry.
Rainy season (May to October) sees high temperatures and humidity, with brief (often daily) downpours making an appearance before the sun reappears.
Dry season (November to April) is comfortable with temperatures hovering around 25°C (77°F) in January and almost no rainfall. This is the best time to visit. The Cambodian New Year, which takes place around April, is also a good time to visit.
Despite it has two distinct seasons, Phnom Penh is widely considered as a year-round destination.
