Located to the south of the Tropic of Cancer, Cambodia overlooks the Gulf of Thailand and faces the vast sea. Low latitudes endow the charming Southeast Asian country with typical tropical climate. It is relatively hot nearly all year around and there are no chilly days existing. Due to relatively uniform altitudes and latitudes, the weather in the whole of Cambodia is highly similar. There is no significant climate difference among various regions.

The average temperature throughout the year is around 27℃ (81℉). The hottest month is April with an average temperature of 30℃ (86℉). However, extremely high temperature over 40℃ (104℉) may often occur in Phnom Penh and Preah Vihear. The coolest months in Cambodia are generally December and January, which have average temperature of 24℃ (75 ℉) and sometimes the temperature can lower to around 16℃ (61 ℉). 

Also influenced by seasonal monsoon, the country has two obvious seasons: the dry season from November to April and the rainy season from May to October. The dry season sometimes also could be divided into the cool season from November to February and the hot season from March to April. Cambodia’s annual precipitation reaches about 2,000mm, 90% of which falls during the rainy season. However, influenced by terrain, the rainfall differs a lot in various regions. In the southern end of the Elephant Mountains, it can reach 5,400mm while there is only about 1,000mm in the regions east of Phnom Penh.
