The country has a tropical climate-warm and humid. In the monsoon season, abundant rain allows for the cultivation of a wide variety of crops. This year-round tropical climate makes Cambodia ideal for developing tourism. Travelers need not fear natural disasters such as erupting volcanoes or earthquakes, and the country is not directly affected by tropical storms.
Cambodia can be visited throughout the year. However those planning to travel extensively by road should avoid the last two months of the rainy season when some countryside roads may be impassable.

The climate distinguished by four major seasons. The most pleasant is the cool-dry season from November to February during which temperatures are cooler (average 17-28º C.). The hot-dry season lasts from March to May (average 30-35º C.). From June to August is the rainy season, during which temperatures are relatively cool (average 27-33º C.). And from September to October is the cool-wet season (average 25-30º C.).
At this time of year it rarely rains in the morning: most precipitation comes in the afternoon, and even then, only sporadically. Rainfall varies considerably from area to area. Whereas the seaward slopes of the south-west highlands (Kompong Som and Kampot provinces) receive more than 5,000 mm of rain per annum, the central lowlands average only about 1,400 mm.
The climate can generally be described as tropical. As the country is affected by monsoon, it is hot and humid with an average temperature around 27.C (80.F). There are two distinct seasons: the Rainy Season and the Dry Season. However, the Dry Season is divided into two sub-seasons, cool and hot. These seasons are:
The Rainy season:
From June till October 27-33 ºC (80-95.f)
The Dry season (cool):
From November till February 17-27 ºC (80-95.F)
The Dry season (Hot) :
From March till May 29-38 ºC (84-100.F)
