Like any country in the Southeast Asian region, Cambodia has a tropical climate, consisting of only two seasons: wet and dry. Wet season begins in May until October while dry season begins November to April.
Cambodia is generally humid. The average temperature in the country is 27°C though it had been known to go down as low as 14°C. For those who are not accustomed to the heat, it is best to avoid going to Cambodia in April, the hottest month of the year. Everything dries up, and one would probably remember—not just the temples and tourist attractions—but the heat and dust while going around the country at this time.
During the South Westerly wet monsoon from May to October, the mornings are clear and sunny, followed by rain for a few hours. This is quite regular, so one can plan sightseeing around it. However, there will be times when it will rain the whole day; prepare to get wet if you go around Cambodia during the rainy season.
There is also the risk of encountering floods at this time. The water level of the Tonle Sap rises, flooding a number of areas around it. The daily rainfall turns the roads into mud pits as well, significantly delaying one’s travel time.
One advantage, however, is the lack of tourists during the wet season. There is no dust, and the energy-draining heat is absent. The rain also makes the greenery in the countryside all the more lush and vibrant.
The best time to visit Cambodia is during its cool months, from November to January. At this time, the skies are generally clear, and the temperature is mild. Scuba divers flock to diving spots in the country during these months for the clear and cool water, and the beaches in Sihanoukville get filled up with beach bums who want to soak the sun and enjoy the clear calm waters of Cambodia.
