Geography of São Tomé and Príncipe
São Tomé and Príncipe is a small nation composed of an archipelago located in the Gulf of Guinea of equatorial Atlantic Ocean. The nation's main islands are São Tomé and Príncipe, for which the country is named. These are located about 300 and 250 km (186 and 155 mi), respectively, off the northwest coast of Gabon in West Africa. The nation's geographic coordinates are a latitude of 1°00′N and a longitude of 7°00′E.
São Tomé and Príncipe constitute one of Africa's smallest countries. They have a total of 209 km of coastline. 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 to the west. São Tomé is 48 km (30 mi) long and 32 km (20 mi) wide and the more mountainous of the two islands. Its peaks reach 2,024 m (6,640 ft). Principe is about 16 km (10 mi) long and 6 km (4 mi) wide, making it the smaller of the two. This makes the total land area of the country 1,001 km², about five times the size of Washington, D.C. 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 Celsius (80 degrees Fahrenheit) and little daily variation. At the interior's higher altitudes, the average yearly temperature is 20 °C (68 °F), and nights are generally cool. Annual rainfall varies from 5000 millimeters (200 inches) on the southwestern slopes to 1000 mm (40 in) in the northern lowlands. The rainy season runs from October to May.
The highest point is Pico de São Tomé, at 2,024 m (6,640 ft).
