In 1864, the Governor of the Bahamas reported that there were 29 islands, 661 cays, and 2,387 rocks in the colony.]
The closest island to the United States is Bimini, which is also known as the gateway to the Bahamas. The island of Abaco is to the east of Grand Bahama. The southeasternmost island is Inagua. The largest island is Andros Island. Other inhabited islands include Eleuthera, Cat Island, Long Island, San Salvador Island, Acklins, Crooked Island, Exuma and Mayaguana. Nassau, capital city of the Bahamas, lies on the island of New Providence.
All the islands are low and flat, with ridges that usually rise no more than 15 to 20 m (49 to 66 ft). The highest point in the country is Mount Alvernia(formerly Como Hill) on Cat Island. It has an altitude of 63 metres (207 ft).
To the southeast, the Turks and Caicos Islands, and three more extensive submarine features called Mouchoir Bank, Silver Bank, and Navidad Bank, are geographically a continuation of the Bahamas, but not part of the Commonwealth of the Bahamas.
The climate of the Bahamas is tropical savannah or Aw. As such, there has never been a frost or freeze ever reported anywhere in the Bahamas - although every few decades low temperatures can fall into the 38°F to 45°F (3°C to 5°C) range for a few hours when a severe cold outbreak comes off the North American landmass. Otherwise, the low latitude, warm tropical Gulf Stream, and low elevation give the Bahamas a warm and winterless climate. There is only a 12°F difference between the warmest month and coolest month in most of the Bahama Islands. Like most tropical climates, seasonal rainfall follows the sun, and summer is the wettest season. The Bahamas are often sunny and dry for long periods of time, and average more than 3000 hours of sunlight annually.
Although rare, tropical cyclones can impact the Bahamas. In 1992 Hurricane Andrew passed over the northern portions of the Islands, and Hurricane Floyd passed near the eastern portions of the islands in 1999.
