It is always hot in Southeast Asia because the equator goes through it. "Heavy tropical rainstorms are common, too," states The Facts on File Childrens Atlas. Most areas of Southeast Asia have a tropical wet and dry climate. It usually gets around 20 inches of precipitation or above. The average January and July temperatures are the same at about 68 degrees F. The fact that Southeast Asians have survived through these temperatures for this amount of time is amazing.
