ial forest, where daytime highs range between , and nighttime lows rarely go below . The average annual temperature is about . In the southern uplands, particularly in the far southeast, winters are cool and dry, whereas summers are warm and damp. The area embracing the chain of lakes from Lake Albert to Lake Tanganyika in the eastern highlands has a moist climate and a narrow but not excessively warm temperature range. The mountain sections are cooler, but humidity increases with altitude until the saturation point is reached; a nearly constant falling mist prevails on some slopes, particularly in the Rwenzori Mountains. The seasonal pattern of rainfall is affected by the DRC's straddling of the equator. In the third of the country that lies north of the equator, the dry season (roughly early November to late March) corresponds to the rainy season in the southern two-thirds. There is a great deal of variation, however, and a number of places on either side of the equator have two wet and two dry seasons. Rainfall averages range from about . Annual rainfall is highest in the heart of the Congo River basin and in the highlands west of Bukavu and with some variation tends to diminish in direct relation to distance from these areas. The only areas marked by long four-month to five-month dry seasons and occasional droughts are parts of the Southeast.
