Here is a page about the Bahamas Geography and Climate.
The Geography of the Bahamas
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. Nassa, 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 elevation of 63 metres (207 ft).
The Climate of the Bahamas
The climate of the Bahamas is tropical savannah climate. The low latitude, warm tropical Gulf Stream, and low elevation give the Bahamas a warm and winterless climate. There is only an 8 °C 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 3,000 hours of sunlight annually.
Tropical storms and hurricanes affect 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.
