The main island has three geographical terrains: the narrow coastal plains, a limestone plateau permeated with karstic caves, and the Haghier Mountains. The mountains rise to 5,000 feet (1,525 m). The island is a little over 80 miles (130 km) long east to west and typically 18-22 miles (30-35 km) north to south.
The climate is generally tropical desert, with rainfall being light, seasonal (winter) and more abundant at the higher ground in the interior than along the coastal lowlands. The monsoon season brings strong winds and high seas.
