This group of 35 islands lies in the Persian Gulf, close to the eastern coast of Saudi Arabia and not far from the western coast of Qatar. Bahrain, the main island from which the country took its name, is connected to Saudi Arabia by a causeway. Another causeway links Bahrain with Al Muharraq, the second largest island in the group. The capital city of Manama is located in the main island. All the islands are low-lying; the highest point is 400 ft (122 m). Most of the land is naturally barren. However, drainage and other schemes have increased the amount of cultivable land. Summers are extremely hot and humid, and there is virtually no rain between June and November. Wintertime temperatures remain around 65ºF (18ºC).
