Geography of Sao Tome and Principe |
||
|
The islands of Sao Tome and Principe, situated in the equatorial Atlantic about 300 and 250 kilometers (200 and 150 miles), respectively, off the northerwest coast of Gabon, constitute one of Africa's smallest countries. Both are part of an extinct volcanic mountain range, which also includes the island of Bioko in Equatorial Guinea to the north and Mount Cameroon[?] on the African west coast. Sao Tome is 48 kilometers (30 mi.) long and 32 kilometers (20 mi.) wide and the more mountainous of the two islands. Its peaks reach 2,024 meters (6,640 ft.). Principe is about 16 kilometers (10 mi.) long and 6 kilometers (4 mi.) wide. Both islands are crossed by swift streams radiating down the mountains through lush forest and cropland to the sea.
At sea level, the climate is tropical--hot and humid with average yearly temperatures of about 27 degrees C (80 degrees F) and little daily variation. At the interior's higher altitudes, the average yearly temperature is 20 degrees C (68 degrees F), and nights are generally cool. Annual rainfall varies from 500 centimeters (200 in.) on the southwestern slopes to 100 centimeters (40 in.) in the northern lowlands. The rainy season runs from October to May.
