Angola's climate varies considerably from the coast to the central plateau and even between the north coast and the south coast. The north, from Cabinda to Ambriz, has a damp, tropical climate. The zone that begins a little to the north of Luanda and extends to Namibe, the Malanje region, and the eastern strip have a moderate tropical climate. Damp conditions prevail south of Namibe, dry conditions in the central plateau zone, and a desert climate in the southern strip between the plateau and the frontier with Namibia. There are two seasons: a dry, cool season from June to late September, and a rainy, hot season from October to April or May. The average temperature is 20° C (68° F ); temperatures are warmer along the coast and cooler on the central plateau. The Benguela Current makes the coastal regions arid or semiarid. The annual rainfall is only 5 cm (2 in) at Namibe, 34 cm (13 in) at Luanda, and as high as 150 cm (59 in) in the northeast.
